There is a hidden indentation issue to do with the "direction = input(..... " line of code. Your "ifs" are too far indented as well. What you need to do is highlight all the code in the movement function then hold down the shift key and press the tab key. This will unindent the code by one tab. Repeat this until "direction = input(... " and the "if" blocks of code are touching the left hand edge. The code should still be highlighted (as long as you have not clicked away from it). Now press just the tab key once. The code should now be correctly indented.

Your code could be more efficient. After the first "if" use "elif"s instead of the repeated "if"s, apart from the last "if" which could be an "else" as it is the last possible choice.

There are one or two other things you could do to improve your code. For instance, how can the user break out of the movement function as it is always called?
