Online Python and AI classes in Tacna, Peru
Tacna's pupils already do well at school, and most of its homes are online, so the question for a Tacna family is less whether to learn Python than how. This page lays out one Python path from age nine to adult, walks through what actually happens in a live online class, and ends with a project on INEI's own Tacna survey in which a program learns that a row of data is not the same thing as a person.

What Tacna learners get
Modern Age Coders teaches Python and AI to learners in Tacna, Peru, live online and in English. Children from about nine type their first Python programs and small AI projects, teenagers go on to complete Python, data science and the PCEP certificate, and adults learn Python for automation, data and generative AI. A mentor teaches each class on live video, in a group of fifteen to twenty or one to one, at whatever hour the learner chooses. The focus is reasoning: learners write and test their own code rather than paste it.
The Python path in Tacna
Three Python courses, one for each stage of life
The same language at every age, taught differently. Start where the learner is today.
How many people live in Tacna, and how connected are its homes?
Tacna is a small department where almost everyone lives in or near the capital, and its homes are better equipped than the Peruvian average. Both matter for live online classes.

In 2025, 42.4% of Tacna homes had a computer, against 33.9% across Peru, and six in ten had an internet service. Typed Python needs a keyboard, so this matters: in Tacna, a family that wants to start usually already has what it needs, or can share a machine with a relative for two hours a week.
School and Python
Do schools in Tacna teach Python?
Not as a subject. MINEDU rates Tacna among the strongest regions for learning, but the national timetable that Tacna's colegios follow has no programming area.
Strong results, no programming slot
When MINEDU published its ENLA 2025 results, it wrote that "Moquegua, Tacna y Arequipa continúan liderando los logros de aprendizaje en todo el país": Tacna is one of three regions that keep leading the national assessment.
Yet the secundaria plan under the regular school day gives Matemática four hours a week and Inglés three, with no area for computing. Digital skill is a transversal competency, expected everywhere and timetabled nowhere.
Where Python is starting
MINEDU's Fábrica de Programadores pilot, launched in July 2025, teaches Python to 1,000 public-school students of 4° and 5° de secundaria in Lima Norte, and those who finish can sit the PCEP exam, an entry-level Python certificate. MINEDU calls it a pilot it wants to replicate across the country.
Until it reaches Tacna, a teenager who wants that same path, Python up to PCEP level, learns it outside school. Our PCEP course covers the same certificate, and we have no connection with MINEDU or the pilot.
Python also opens a contest door. The Olimpiadas Peruanas de Computación, run by UTEC and free for every secundaria student, allow C++ or Python in their first round and only C++ in the in-person final, and they ban the use of generative AI to solve problems. A Tacna student who has learned to reason in Python can enter the first round and learn C++ later. Our page on Python courses in Peru compares the routes in more detail.
One language, every age
What does the Python path look like from age 9 to adult?
Python is the same language for a ten year old and a forty year old. What changes is the pace, the projects and the reason for learning.

Using AI tools with judgement
Stages and ages are ours. Secundaria grades follow MINEDU's normative ages at 31 March (1° de secundaria at 12, 5° at 16).
Children, about 9 to 12
The first weeks are about typing without fear: a misspelt word gives an error, the mentor shows how to read it, the child fixes it. By the end of the course children write short programs that make choices and repeat.
Teenagers, 13 to 18
Teenagers learn why code works, not just that it does. They write functions, test them, and use Python on real files. Some go to PCEP; others to data science or to the OPI's Python round.
Adults
Adults usually arrive with a goal: a report to automate, a dataset to understand, an AI tool to use well. The course starts from zero but quickly bends towards that goal.
How live online works
How does a live online Python class actually work?
It is not a recorded video. A mentor and the learners are on the same call at the same time, and the learners write the code themselves.
Join the call. At the agreed hour the learner opens the class link on a laptop or desktop. A headset is useful; a webcam is welcome but not required.
A short warm-up. The mentor asks what happened last time, or sets a two-minute puzzle, so everyone is thinking before any code appears.
One new idea. The mentor shares their screen and shows one idea, for example a loop that adds up a list, explaining each line in plain English.
Learners type it. Every learner writes the code on their own computer. When something breaks, the mentor asks the learner to read the error aloud and guess the cause before helping.
A small challenge. The class ends with a task to change the program, for example to add up only some of the list. Learners share screens to show their answer.
Practice between classes. A short exercise follows each class. Parents of younger learners receive a note on what was covered and what was hard.
Group or one to one
A group class has fifteen to twenty learners of a similar age with one mentor, and meets twice a week. Learners hear other people's questions, which often turn out to be their own.
A one-to-one class is just the learner and the mentor, at hours the two of them agree. It suits adults with irregular work hours and learners who want to go faster or slower than a group.
What a learner in Tacna needs
A computer with a keyboard, a browser and a steady connection. Python itself is free; the mentor helps install it in the first class, or the class uses an online editor.
No previous coding is needed for any first course on this page. What helps most is curiosity and the patience to read an error message twice before asking for help.
Taught in English
Are the classes in Spanish?
No. Every class is live, online and taught only in English. For many Tacna learners that is part of the attraction; for some it is a hurdle, and we would rather say so now.
Tacna on EF's English index
In EF's English Proficiency Index 2025, Peru scores 519, in the moderate band, and Lima city 555, in the high band. The Tacna region scores 476, which EF places in its low band. EF gives no figure for Tacna city on its own.
EF's scores come from people who chose to take its online test, so they describe a pattern, not any one learner. Still, they suggest many Tacna learners will be practising English as they learn Python.
Why Python helps
Python's keywords are short English words: if, else, for, while, print, return. A learner who uses them every week is also building English vocabulary, and the error messages Python prints are in English too.
Our mentors speak slowly, rephrase rather than repeat, and give learners time to answer. Adults who read English well but speak it less often find the classes a gentle way to practise listening.
If you would like Python explained with Spanish-speaking families in mind, our Spanish page curso de Python en inglés answers the same questions in Spanish. The classes themselves are still in English.
A real Tacna project
Does a survey file of Tacna show who lives in Tacna?
Not until you weight it. Our teenage and adult learners use INEI's employment survey for the Tacna department to learn a lesson that matters in data science and in AI: a row of data is not a person.
The data
INEI publishes the microdata of its Encuesta Permanente de Empleo Nacional for each department as open data. The EPEN Departamentos 2025 dataset carries the Open Data Commons Open Database Licence (ODbL), a share-alike licence: any database we built from it and released would have to carry the same licence. This page publishes only our counts and our code.
The Tacna file for 2025, saved as tacna-epen-2025.csv, has 13,420 rows, one for each person in the homes INEI visited across the twelve months. We use four columns: whether the home is urban or rural, the person's age, their highest level of study, and the weight, a column called FAC300_ANUAL.
What a weight is
A survey cannot visit every home, so INEI visits a sample and gives each answer a weight: roughly, how many people in Tacna that one answer stands for. INEI's quarterly data dictionary calls the same kind of column "Factor empleo trimestral", an expansion factor.
Surveys often visit rural areas more heavily than their size, so that there are enough rural answers to say something useful about them. Each rural answer then carries a smaller weight.
Version 1: count the rowsPython
import csv
people = 0
rural = 0
degree = 0
with open("tacna-epen-2025.csv", encoding="latin-1") as src:
for rec in csv.DictReader(src):
if rec["FAC300_ANUAL"] == "" or rec["C208"] == "" or rec["C366"] == "":
continue
if int(rec["C208"]) < 25:
continue
people += 1
if rec["AREA"] == "2":
rural += 1
if rec["C366"] in ("11", "12"):
degree += 1
print("Rows, aged 25 and over:", people)
print("Rural share of rows:", round(100 * rural / people, 1), "%")
print("University degree share of rows:", round(100 * degree / people, 1), "%")
It prints: Rows, aged 25 and over: 7126, Rural share of rows: 13.6 % and University degree share of rows: 15.7 %.
The program keeps adults aged 25 and over who have a weight and an answer about their studies, then counts. It reports that 13.6% of these adults live in rural areas. That is true of the rows, but is it true of Tacna? INEI chose which homes to visit, so the rows reflect INEI's plan as much as the department.
Version 2: add up the weights insteadPython
import csv
people = 0.0
rural = 0.0
degree = {"1": 0.0, "2": 0.0}
total = {"1": 0.0, "2": 0.0}
with open("tacna-epen-2025.csv", encoding="latin-1") as src:
for rec in csv.DictReader(src):
if rec["FAC300_ANUAL"] == "" or rec["C208"] == "" or rec["C366"] == "":
continue
if int(rec["C208"]) < 25:
continue
w = float(rec["FAC300_ANUAL"])
people += w
total[rec["AREA"]] += w
if rec["AREA"] == "2":
rural += w
if rec["C366"] in ("11", "12"):
degree[rec["AREA"]] += w
print("People this stands for:", round(people))
print("Rural share of people:", round(100 * rural / people, 1), "%")
print("Degree share, all:", round(100 * (degree["1"] + degree["2"]) / people, 1), "%")
print("Degree share, urban:", round(100 * degree["1"] / total["1"], 1), "%")
print("Degree share, rural:", round(100 * degree["2"] / total["2"], 1), "%")
It prints: People this stands for: 270397, Rural share of people: 8.3 %, Degree share, all: 15.3 %, Degree share, urban: 16.4 % and Degree share, rural: 3.9 %.

Data: INEI, Encuesta Permanente de Empleo Nacional (EPEN) Departamentos 2025, Tacna file, published on datosabiertos.gob.pe under the ODbL. Every figure in the table is our own calculation. "University degree" means codes 11 (superior universitaria completa) and 12 (maestría or doctorado) in the C366 column. Of the 13,420 rows, 4,327 have no weight, mostly children under 14, and 869 adults aged 25 and over left the study question blank; both are skipped. Urban rows carry about 40 people each on average and rural rows about 23, by our division.
Weighting moves the rural share from 13.6% of rows to 8.3% of people, because INEI deliberately visited more rural homes than their share of Tacna. The degree share barely moves overall, 15.7% to 15.3%, but splitting it by area shows the real story: 16.4% of urban adults hold a degree, and 3.9% of rural adults do. The sum of weights, about 270,397 adults aged 25 and over with an answer, is our estimate from the survey, not a census count.
This is the habit that separates careful data work from guessing, and it matters for AI too. A model trained on rows that over-represent one group will learn that group's patterns more strongly unless someone weights or balances the data. Our learners meet that idea first with a Tacna survey, where they can check every number themselves.
Ages 9 to 12. A class has 20 children: 15 from the city and 5 from the countryside. A school has 300 city children and 20 country children. If each class child "stands for" some school children, how many does each city child stand for, and each country child?
Ages 13 to 15. Run Version 1, then change it to count adults aged 25 to 39 only. Does the rural share of rows go up or down?
Ages 16 and over. Add the weights for every row with a weight, of any age. Compare the total with INEI's 2025 census figure for the department, 389,226, and explain why the two need not match.
Adults. Write one function, share(rows, test, weighted), that gives either kind of share for any test, and use it to print both columns of the table above.
Class times
What time are the classes for someone in Tacna?
Whenever the learner chooses. Tacna is on Peru time all year, and the mentor works to that clock.

Late learners
Peru is on UTC minus 5 hours every day of the year and has had no daylight saving since 1994 (tz database, America/Lima; INACAL keeps the official time). India is on UTC plus 5 hours 30 minutes. The gap is a fixed 10 hours 30 minutes, with India ahead.
Because neither country changes its clocks, the slot you book stays put all year. You pick a time in Tacna's clock when booking and the mentor sees the India equivalent. Adults often take one-to-one classes at a lunch hour or late evening; teenagers often prefer the hour after colegio.
Milestones

Tacna learners ask
Python and AI classes in Tacna: questions and answers
Are the classes in Spanish?
No. Teaching is in English only, in every live online class. Mentors speak clearly and slowly, match the learner's pace and accent, and explain each line of code in simple words. Python keywords are English anyway, so the language of the class and the language of the code are the same.
Is there a Python course in Tacna?
Yes, live online. Learners anywhere in Tacna join from home on a laptop or desktop. There is no classroom to travel to, and classes run at whatever hour you book.
From what age can someone learn Python?
From about nine, when typing becomes comfortable. Younger children start with Scratch blocks and move to Python later. There is no upper limit: our adult learners include people in their sixties.
Can my teenager get the PCEP certificate?
Our PCEP and PCAP course prepares learners from about 13 for the Python Institute certificates. MINEDU's Fábrica de Programadores pilot uses the same certificate, but we are not connected with MINEDU or the pilot.
Do schools in Tacna teach programming?
No. Tacna is among the regions MINEDU says lead learning results, but the national secundaria timetable has no programming area. Digital skills are transversal, used in every area and timetabled in none.
What time are the classes?
Any day, any time, flexible: choose a batch, or for a very personalised plan choose 1-on-1 at the hour that suits your family. India runs 10 hours 30 minutes ahead of Tacna all year, so 12:30 in Tacna is 23:00 for the mentor.
What do I need at home?
A laptop or desktop with a keyboard, a browser and a steady connection. Python is free to install, and the mentor helps in the first class. INEI counted a computer in 42.4% of Tacna homes in 2025.
Will I learn AI as well as Python?
Yes, step by step. Children meet simple AI projects, teenagers build first machine learning models, and adults learn generative AI and automation. In every course the learner writes and checks the code rather than copying AI output.
How are fees charged?
Monthly, in US dollars, by card. Your bank converts the amount to soles. A visitor from India sees rupees. The first class is a free trial with no card details.
Is there a certificate?
Courses that include one end with our own certificate of completion. It is not a Peruvian qualification, and no Peruvian school, university or ministry issues or recognises it; the PCEP certificate is awarded by the Python Institute after its own exam.
