Question

I am new to python and I’m wondering, how I would go about removing items from a list. Say I have the list:

a=[(102,12,0),(123,12,0),(124,12,1)]

I would like to remove the items that have a 0 at the end, so my list would end up like:

a = [(124,12,1)]

Answer 1

here:

a = [i for i in a if i[-1] != 0] #list comprehension (1 line) method.

“normal” way to do without list comprehension when the parent list is also destination list.

tmp = []
for i in a:
    if i[-1] != 0:
        tmp.append(i)
a = tmp

in action:

>>> a=[(102,12,0),(123,12,0),(124,12,1)]
>>> a = [i for i in a if i[-1] != 0]
>>> a
[(124, 12, 1)]
>>>
