Python

Question

Can you please explain me, how this code works?

n=[1,2,3,4,5,6]
for i, item in enumerate(n):
n[i]*=2
print(n)

I can’t understand, why and how we use “item” and “enumerate”

Answer 1

"i" stores a number, the index
And
"item" stores a value, the item

Cristian Gabriel Mazzulla , thx!

Answer 3

I don't know what it would be used for in a list, but in that attached page it uses it for a tuple, which makes more sense since they are not indexed
