Searching for substring in element in a list an deleting the element

Question

I have a list and I am trying to delete the elements that have 'pie' in them. This is what I've done:

['applepie','orangepie', 'turkeycake']
for i in range(len(list)):
    if "pie" in list[i]:
         del list[i]

I keep getting list index out of range, but when I change the del to a print statement it prints out the elements fine.

Answer 1

Instead of removing an item from the list you're iterating over, try creating a new list with Python's nice list comprehension syntax:

foods = ['applepie','orangepie', 'turkeycake']
pieless_foods =  [f for f in foods if 'pie' not in f]
