how to delete the last value of an array in 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: exclude last value of an array python

my_array=np.arange(10)
my_array[:-1]
