list remove last if python code example

Example 1: how to delete the last item in a list python

# 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)

Example 2: remove last element from dictionary python

D={1:'a',2:'b',3:'c'}
x=D.popitem()
print(D,x)
>>>{1:'a',2:'b'} (3,'c')
#x is the removed item, D is the rest of the dict
