🧠 Think Like Python

Suppose you want to know if a username exists.

🔻 Many beginners write:

found = False

for user in users:
    if user == "Alex":
        found = True
        break

🟢 Python gives you a simpler solution.

found = "Alex" in users

Less code. More readable. Usually faster to understand.

Whenever Python has a built-in way to express an idea, prefer it.
