For loop in python

Question

Hey, I've seen some for loops that have a variable name before the for statement. Can you give me an example and explain what it does?

Answer 1

Maybe it was a list comprehension?

lst = [i for i in range(10)] # something like this?

This creates a list populated by each value that i takes in the range given.

print(lst) # [0,1,2,3,4,5,6,7,8,9]

Answer 2

Ipang I cant find it.. that's why I've asked.. sorry

Answer 3

Russ yes! Thank you

Answer 4

Um, no. Not to get the same result. Have you tried it yourself?

Answer 5

yahel
Can you instead copy/paste that code you seen in the Description (just the loop part)? I think it makes more sense for others to explain ...

Answer 6

Russ but cant I just do it without the i before the for keyword?

Answer 7

Russ ok, thanks!
