Learn Python Basics By Doing

Learn why we use comments in Python, and how to write single-line and multiline comments with # and triple quotes to explain code and prevent execution.

Discover how to create and use Python variables without explicit declaration, assign dynamic types, print values, perform multi-variable assignments, and manage global versus local scope with the global keyword.

Master Python data types with strings, integers, floats, and complex numbers, and verify types using print and type; explore lists, dictionaries, and range-based indexing from zero to five.

Explore integers, floats, and complex numbers, and learn how to check a variable's type with type(). Convert values using int, float, and complex to verify the results.

Explore Python strings: use quotes, assign to variables, print, create multi-line strings with triple quotes, concatenate, index, slice, and check substrings with in and not in.

Explore how Python string methods transform text, including capitalize, upper, lower, title, casefold, and count for occurrences, along with isalpha, isnumeric, and isalnum.

Demonstrate arithmetic operators, including addition, subtraction, multiplication, division, modulus, exponentiation, and floor division, using two variables with practical code examples.

Explore Python assignment operators, including =, +=, -=, *=, /=, //=, %=, and **=, with practical examples showing how values are assigned and updated.

Explore Python comparison operators, including equal, not equal, greater than, less than, and their inclusive forms, with simple examples that show true or false outcomes.

Explore identity operators in Python, learning how 'is' and 'is not' compare object identity—whether two variables reference the same object rather than just having equal content.

Master Python membership operators by using in and not in to test values in a list, with apple and orange examples showing true or false.

Learn to write Python if statements, including if, elif, and else, with proper indentation. Practice using comparison operators such as greater than, and, or, and shorthand forms.

Explore how Python while loops work by counting from one to five, printing each value, and incrementing until the condition is false, with break and continue concepts.

Master Python for loops by iterating over lists, strings, and other iterables, using break, continue, range, and nested loops, with else and pass blocks for control flow.
