Python Programming: Zero to Hero

1. The Basics

Variables and printing are the foundation of Python.

name = "Gemini"
age = 25
print(f"Hello, {name}!")
    

2. Data Structures

Python organizes data into Lists, Tuples, Sets, and Dictionaries.

fruits = ["apple", "banana", "cherry"]
user_info = {"name": "Dev", "role": "Coder"}
    

3. Control Flow

Control flow allows your program to make decisions and repeat tasks using If Statements and Loops.

Conditionals (If/Else)

score = 85
if score >= 90:
    print("Grade: A")
elif score >= 80:
    print("Grade: B")
else:
    print("Grade: C")
    

Loops

Use for loops to iterate over sequences and while loops for conditional repetition.

# For loop
for i in range(3):
    print(f"Iteration {i}")

# While loop
count = 5
while count > 0:
    print(count)
    count -= 1
    

4. Advanced Data Types

Understanding the difference between Mutable (changeable) and Immutable (fixed) structures is key.
