Error: Unboundlocalerror: local variable 'p1pos' referenced before assignment

python

  • The variable is defined outside the scope of the function, so it is read-only, you cannot change its content and hence the error. You can send it as an argument of its function, play all the logic inside a class or else (something little recommended) declare it as global.

  • If I put var as argument, when calling the function, it will be able to edit the value of the variable that is outside the function?
