Lesson 8: Strings in Depth ✂️

Welcome to Lesson 8! Let's master strings — text data. Manipulate, slice, and format them!

🔤 String Basics

Strings are just text in quotes:

name = "Alex"

✂️ Slicing and Indexing

Get parts of strings:

word = "Python"
print(word[0])      # 'P'
print(word[2:5])    # 'tho'

🔄 String Methods

Useful tools:

• .upper(), .lower(), .title(), .replace(), .find(), .split()

msg = "hello world"
print(msg.upper())

🎨 Formatting

Combine with variables:

name = "Alex"
age = 15
print(f"My name is {name} and I'm {age}")

🎯 Key Takeaways

✅ Strings hold text ✅ Slice, change, and format strings ✅ Tons of built-in tools!
