Basic Python Concepts

Variables

Variables store data in your program:

name = "Alice"
age = 30
height = 1.75

Data Types

Python has several built-in data types:

Strings: "Hello"
Integers: 42
Floats: 3.14
Booleans: True or False
Lists: [1, 2, 3]
Dictionaries: {"name": "Bob", "age": 25}

Control Flow

If Statements

if age >= 18:
    print("You're an adult")
else:
    print("You're a minor")

Loops

For loop:

for i in range(5):
    print(i)

While loop:

count = 0
while count < 5:
    print(count)
    count += 1

Functions

Functions help organize and reuse code:

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

message = greet("Charlie")
print(message)
