If I have a list
x=[0.0,0.0,2.0,3.0,0.0,2.0]
and I basically want to count the amount of items in the list but only start after the leading zeroes, how would I do that? Keep in mind that I want to count the zero in the middle of the list but not the ones at the beginning.
I’ve tried this:
n=0 for i in x: while i==0.0: break if i!=0.0: n=n+1
But it didn’t get 4, which is the output I want as I want to include 2.0,3.0,0.0,2.0 only.

You can simply wrap your counter code in a conditional, with something like this:
x=[0.0,0.0,2.0,3.0,0.0,2.0] start_counting = False item_count = 0 for i in x: if i != 0.0: start_counting = True if start_counting: item_count += 1
item_count
will now have the amount of items in the list without the starting 0.0s
