Python Programming for Complete Beginners

Learn how to name variables in Python with snake_case and CamelCase, create unassigned variables, assign values later, and print strings and numbers to pass tests.

Learn how to swap two integers using a temporary variable by copying int one to temp, moving int two into int one, and then restoring int two from temp.

Apply math operators in Python to calculate a rectangle's area and perimeter using length 20 and width 10, with variables, formulas, hints, and solution walkthrough.

Discover how Python f-strings replace concatenation by embedding variables, apply formatting options for alignment, width, and padding, and display numbers in decimal, percent, binary, octal, and hexadecimal.

Explore truthiness in Python by showing how values are treated as true or false in if statements, including numbers and nonempty strings versus zero, empty strings, and none.

Create two rectangle functions that return the area and perimeter, with a default width of ten; use calls area(length, width) and perimeter(length, width).

Define rectangle functions to compute area and perimeter with length and width, set a default width of ten, and return length times width for the area.

Explore tuples in Python as immutable containers that hold duplicates and various data types. Learn packing and unpacking, index and count methods, and how tuples enable nested data and coordinates.

Explore Python dictionaries: create key-value pairs in curly braces, look up by key with get, handle missing keys, update, remove, and work with keys, values, and nested dictionaries.

Learn to implement a repeat word function with word and count parameters, returning the word repeated count times. Compare looping and string multiplication to solve the task.
