UnboundLocalError: Lokale Variable 'Name', auf die vor der Zuweisung verwiesen wird

Question

In meiner Bedingung versuche ich dem Variablennamen einen neuen Wert zuzuweisen, aber ich erhalte den Fehler unten.

Nach meinem Code ausführen, erhalte ich UnboundLocalError: local variable 'name' referenced before assignment

Haben Sie Ahnung haben, um es zu beheben?

Ich weiß nicht, warum ich das immer, wenn die Variable

Funktionen global ist, ihre eigenen Anwendungsbereich haben. Um auf eine globale Variable zuzugreifen, müssen Sie dies explizit sagen:

def create_contributor_minimum_requirements(driver): 
    global name 
    ... 

Ich hoffe, es hilft!
