By the end you'll be able to
- Read and write Python comfortably for everyday automation
- Work with files, APIs, and data structures in Python
- Build small CLI tools and scripts that solve real problems
- Manipulate spreadsheet-style data using pandas
- Foundation for Data, ML, and AI tracks
Is this course for you?
This is right for you if you…
- You're starting from scratch and want a language that works for everyday automation, data, and AI
- You've tried Python tutorials and they ended at 'print hello world' — you want to actually build something
- You're aiming at Data / ML / AI tracks where Python is the lingua franca
Don't take this course if you…
- You're already writing Python at work — this course is foundations; take an advanced AI/data course instead
- You only want C# or Java — Python is a separate ecosystem. The C# foundation course (#1) is the alternative
- You want to build mobile apps — Python isn't the right tool. Different course family entirely

Oleksii Anzhiiak is a Software Architect, Senior .NET Engineer, and Co-Founder of ToyCRM.com and ProfectusLab. With over 15 years of experience, he specializes in distributed systems, cloud infrastructure, high-load backend development, and identity platforms. Oleksii designs complex architectures, builds secure authentication systems, and develops modern engineering education programs that help students achieve real career results.
Currently leads architecture for ToyCRM.com — a multi-tenant CRM platform built on .NET by our team. The same patterns and design decisions used there appear directly in the courses: identity & auth, distributed services, code review culture. You learn from engineers actively shipping production code, not from a textbook.
Syllabus
This course takes you from zero to a confident Python foundation:
- 1 Module 1: Python basics — syntax, variables, types, operators
- 2 Module 2: Control flow — conditions, loops, comprehensions
- 3 Module 3: Functions — arguments, return values, lambdas, closures
- 4 Module 4: Data structures — lists, tuples, sets, dictionaries
- 5 Module 5: OOP — classes, objects, inheritance, magic methods
- 6 Module 6: File I/O and modules — reading/writing files, os, pathlib, sys
- 7 Module 7: Error handling and testing — exceptions, unittest, pytest basics
- 8 Module 8: Practical scripting — automation tasks, working with JSON/CSV/APIs
Prerequisites
No programming experience needed. Suitable for complete beginners.
No prior programming experience required. Basic computer skills are sufficient.
What you'll build
You leave able to write working Python from a blank file — automation scripts, simple CLI tools, basic data analysis. Python is the entry point to Data, ML, and AI work; this course makes sure that entry is solid.
- Python syntax, types, control flow, functions
- Lists, dicts, sets, comprehensions
- File I/O and HTTP requests
- Error handling and modules
- pandas basics for data work

Spec-Driven Development: When Your Spec Becomes the Codebase
I haven't written a function by hand in two months — and the codebase has never been healthier. Here's how spec-driven development changed what 'engineering work' means in 2026, the rules that keep the discipline honest, and where it still falls apart.

A senior engineer's honest take on choosing between C# and Python as your first serious language — based on job market data, learning curve, and long-term career impact.
First lesson on us. Decide after meeting your instructor.
Sit in on the first session. If after lesson 1 you decide the instructor isn't the right fit, you don't pay for it — and no awkward conversation. (Trial offer applies to courses with more than 5 lessons; this one qualifies.)
Pricing & what's included
What's included
- 16 live sessions × 2 hours each — taught by the instructor, not a recording playback
- Slide deck for every session — yours to keep and refer back to
- Working code files and any data files used in class — cloned to your machine
- Weekly homework with personal code review from the instructor
- Recording on request — give the teacher a heads-up ("can't make Tuesday, please record it") and the session is recorded for you
Frequently asked questions
How much time per week will this take?
Plan for the live sessions plus roughly 1.5–2 hours of practice per session. Most students who finish on schedule put in 4–6 hours a week total. If you put in less, you still finish — it just takes longer.
What if I miss a class?
Tell the teacher BEFORE the session — "I can't make Tuesday, please record it" — and the teacher records that lesson and sends it to you. Recordings aren't a default catch-up archive; they're produced on request when you give a heads-up. After the lesson you do the homework, bring questions to the next session.
What's included in the price?
Live sessions with the teacher; the slide deck for each session (yours to keep); the working code files and any data files used in class; weekly homework with code review; and recordings of the sessions you give advance notice for. Anything beyond that — a certificate, alumni access, mock interviews — is listed explicitly in "What's included" above the FAQ for the courses where it applies.
What if I sign up and the teacher isn't a fit?
For courses with more than 5 lessons, the first session is effectively a trial — if after lesson 1 you decide the teacher isn't a fit, you don't pay for it. We'd rather you walk away after one lesson than push through 9 weeks of bad chemistry. (Courses with 5 or fewer lessons are short enough that the standard pricing applies — the trial offer doesn't make sense at that length.)
Can I get a refund partway through?
Yes, while more than half the course is still unused — i.e. you've attended fewer than 50% of the lessons. The refund covers the unused portion proportionally. Past the halfway point we don't refund, on the assumption that the value has been delivered.
Can I switch the language of instruction?
The live sessions run in the language listed under "Available Languages" above. Slides and code files are typically available in all four (English, Russian, Ukrainian, Georgian). Many students attend sessions in one language and read materials in another — that's normal.
Will I be ready for a real job after this course?
One course rarely gets anyone hired by itself — for any field. What this course gives you is the foundation a junior hiring manager expects: working code you wrote yourself, the vocabulary to read other people's code, and the practice habits that make you employable. The honest answer to "am I ready?" is on our roadmap (link in the page header) — open the level you want to reach and read the "You're ready when" checklist.
Can I pay in instalments?
Yes for courses with a "Monthly Payment" option in the at-a-glance ribbon — usually two or three equal monthly payments. Courses without that option are paid in one go. If the price is the blocker, write to us — we look at every case.
