Software · Free Learning Path

Learn Python.
Then go build.

Three units, sixty questions, zero filler. Each unit covers a slice of Python you actually need, and ends with a free 20-question quiz that scores you and tells you exactly what to work on next. No signup. No video padding. No certificates designed to be framed.

The Path

From zero to writing your own classes.

Work the units in order if you’re new. Skip ahead if you’re reviewing. The quizzes tell you whether you actually got it or just felt like you did.

Unit 1 · Beginner

Fundamentals

Variables, types, operators, strings, conditionals, functions, and exceptions. Everything you need before you can write a useful 20-line program.

Programming concepts (input → process → output)

Data types & variables

Numbers & operators

Strings & their methods

Conditionals & booleans

Functions & methods

Errors & exceptions

Sets, tuples & dictionaries

While loops

For loops & range

Break, continue & nesting

Arguments & return values

Classes & objects

__init__ & attributes

Methods & self

Inheritance

Variable scope

Modules & imports

File I/O
