π Python Strings look simpleβ¦ but mastering them unlocks a LOT of Python!
Strings are everywhere β from web scraping and data cleaning to APIs, automation, NLP, and everyday Python programs.
Here are the essentials you should know π
πΉ String basics & structure
πΉ Zero-based indexing
πΉ Positive & negative indexing
πΉ Slicing: st[start:end]
πΉ Step slicing: st[start:end:step]
πΉ Reversing: st[::-1]
πΉ Concatenation with +
πΉ Repetition with *
πΉ Useful methods: upper(), lower(), strip(), replace(), split(), find(), count()
πΉ f-Strings for formatting
πΉ String immutability
Example:
st = "Python"
print(st[0]) # P
print(st[-1]) # n

print(st[::-1]) # nohtyP
π‘ Tip: Don't just memorize string methods. Practice indexing and slicing until they become second nature.
