python remove last element from list

# The pop function, without an input, defaults to removing 
# and returning the last item in a list.
myList = [1, 2, 3, 4, 5]
myList.pop()
print(myList)

# You can also do this without returning the last item, but it is
# much more complicated.
myList = [1, 2, 3, 4, 5]
myList.remove(myList[len(myList)-1])
print(myList)

record = record[:-1]

test = ["80010","80030","80050"]
newtest = [x[:-1] for x in test]

>>> l = list(range(1,5))
>>> l
[1, 2, 3, 4]
>>> l.pop()
4
>>> l
[1, 2, 3]

l = list(range(1,5))
l = test_list[: len(test_list) - 2]
