unboundlocalerror local variable referenced before assignment python
"""
This happens when python thinks that your variable is local
(the scope is only within a specific function) and/or that
you have not assigned a value to the variable before in this
specific function (scope).
try:
- assigning the variable a value within the function
- Passing the variable to the function using it when calling the function
- Declaring the variable as global (bad practice)
