NameError: name 'Key' is not defined

Question

I am getting a NameError, when trying to call in def Password() saying that 'Key' is not defined. When clearly I have defined it in the RandomKey(): function and returned the value... How do I fix it?

def RandomKey():

            Main_Key = random.randint(1,25) 
            Key = Main_Key
            return Key 

def Password():
            while T:
                    pass_code = (int(input('Enter The Key: '))) 

                    if pass_code == Key and User_Menu_Input == 2:
                          time.sleep(.3) 
                          print('Key recognized... Transfering to the Encryption Menu') 
                          Timer(Time)
                          ReadFile() 
                          break
                    elif pass_code == Key and User_Menu_Input == 3:
                          time.sleep(.3) 
                          print('Key Correct... Transfering to Decryption Menu') 
                          Timer(Time) 
                          Decrypt() 
                          break

                    else:
                            print('Key Not Recognized... Try Again!')

Of course Key is not defined in reason it's private var in other function. You can fix it with 1000 variations. In first one try this

Key = RandomKey()
if pass_code == Key
