def issue - NameError：name 'passwordchecker'が定義されていません

Question

パスワードチェッカーとメニュー付きの発電機を作っていますが、パスワードチェッカーはそれ自体でうまく動作しますが、メニューはコードと一緒には機能しません。それは自分自身でメニューを試してみるとどちらもうまくいかない。これらは私が受け取っているエラーです：

私は間違って何をしたのか分かりませんので、できるなら助けてください。

私はあなたがpasswordchecker()とpasswordgenerator()の定義以下にmainmenu()にごコールを移動する必要がpycharmとPython 3.6.3

を使用しています。それ以外の場合は、mainmenu()が呼び出すときには定義されません。

import re

      if selection == 1: 
       passwordchecker()

     except ValueError:

    incorrectpassword = True 

    while incorrectpassword:

     if len(password) < 8:

passwordchecker() 


def passwordgenerator(): 

    print("Work In Progress") 

mainmenu() 
mainmenu() 

Answer 3

定義される前にいくつかの関数が呼び出されたようです。 mainmenu（）の前にpasswordgenerator（）とpasswordchecker（）を置き、あなたが好きなように呼び出す。

また、このプログラムをループに入れて、 というループを変数に依存させることをお勧めします。そんなにエレガントになるでしょう。次に、あなたの関数の名前を次のように変更します。

mainMenu() 
passwordGenerator() 
passwordChecker() 

もっとプロフェッショナルに見えます。がんばろう！
