Answer 1

read tracebacks from bottom to top.
You have an error

File "C:\Users\Student\AppData\Local\Programs\Python\Python310\lib\random.py", line 378, in choice
    return seq[self._randbelow(len(seq))]
IndexError: list index out of range

So you are trying to access a non-existent index. Find out what's wrong
