Removing Elements From A List

How can i remove elements with a value of 0 as they pop upp in this loop? y = [4, 2, 7, 9] x = input('run?') while x: for i in range(len(y)): y[i] -= 1 y.append(len

Solution 1:

you could always use a list comprehension to filter them:

for i in range(len(y)):
    y[i] -= 1
y = [x for x in y if x != 0]  # <-- added here
y.append(len(y))

EDIT:

I'm silly - these operations could even be combined as so:

while whatever: #<-- fix as suggested by comment on your question
    y = [z-1for z in y if z > 1]
    y.append(len(y))

Solution 2:

y = filter(lambda i: i != 0, y)
