Question with Python for loop, I'm a beginner

Question

I don't understand why if my list name is words I can set a for loop with the counter variable called words just like the list. How does Python chooses which variable is the list or the counter if they have the same name?? I know it's better practice if I name them different, I just wanna know why Python allows me to call them the same??

Answer 1

words = ["hello", "world", "spam", "eggs"]
for e in words:
print(e + "!")
yes i agree this is more readable. its because the variable words used in the for loop has a smaller scope so it doesnt affect the variable words outside the for loop
