🧱 Module 01: Foundations¶

The building blocks of every program. Master these, and you'll have a solid base for everything else.

What's in This Module¶

Topic	Description
01_variables_and_types	Storing and naming data
02_operators	Math, comparison, and logic
03_control_flow	Making decisions with if/else
04_loops	Repeating actions
05_functions_basics	Creating reusable code blocks
06_input_output	Getting and displaying data

Learning Objectives¶

By the end of this module, you will:

✅ Store data in variables with appropriate types
✅ Perform calculations and comparisons
✅ Make your program take different paths based on conditions
✅ Repeat code efficiently with loops
✅ Organize code into reusable functions
✅ Interact with users through input and output

Key Concepts Preview¶

Variables¶

name = "Alice"      # A string (text)
age = 25            # An integer (whole number)
height = 1.75       # A float (decimal number)
is_student = True   # A boolean (True/False)

Operators¶

total = 10 + 5      # Math: 15
is_adult = age >= 18  # Comparison: True
can_vote = is_adult and is_citizen  # Logic

Control Flow¶

if age >= 18:
    print("You can vote!")
else:
    print("Too young to vote.")

Loops¶

for i in range(5):
    print(i)  # Prints 0, 1, 2, 3, 4

while count < 10:
    count += 1

Functions¶

def greet(name):
    return f"Hello, {name}!"

message = greet("World")  # "Hello, World!"

Input/Output¶

name = input("What's your name? ")
print(f"Nice to meet you, {name}!")
