Python. How to remove zeroes from a list in Python

X = [0,5,0,0,3,1,15,0,12]

for value in range(0,len(X)):

    if X[value] <= 0:

        del X[value]
        print(X)
print(X)

I run the code but then i get an error saying that the list is out of index range.
Can someone please help me out on how to correct this mistake
