Problem in python

Why is the list name shown as none after appending an element. What does that that "None" mean? I am new to programming and I have just started with python. Please ignore any silly mistakes by me. https://code.sololearn.com/c89McJc8Up4f/?ref=app

You have to declare firstly your added_state variable as empty list.then assign to it state list .Or you have to remove assignment and append directly to state list with no need to added_state variable

You will declare an empty list .Here you declare added_state = [] with no value.Then you can append to it.
