List operation error

[Hermann_Fegelein]

Hello everyone,
I recently registered in order to ask for help. Being a total newbie, I decided to practice with list operations, and I wanted to create a very simple program, simply using "append" and "pop".

random_list=[1, 2, 4, 8]
print(random_list.append("num"))
print(random_list.pop(1))

The bad news is, though, I'm not getting the output i wanted: while it should be [1, 2, 4, 8, "num"] and [1, 4, 8], what I get is:
None ; 2

What am I doing wrong?
Thanks in advance for your generous help, dear coders!
