for x in len()? - IAMK - Apr-14-2018
I've got the following code at the moment:
aLen = len(sa_data[1]) for a in range(1,aLen):Is there a way to simply say:
for a in len(sa_data[1]):?

for a in range(len(sa_data[1])):but if sa_data[1] is iterable why not:
for item in sa_data[1]:where item is your final target.

As for the second solution, I'm using the number of the elements rather than the data, so the first solution is better for me.

No question is a stupid question if you don't know the answer.

Anyway, thanks. I will replace where
range(len()) appears in My Code with enumerate().
