私のプログラムは、仮想のマクドナルドになることを意図しています。すべて正常に動作しますが、集計方法の 1 つについて助けが必要です。このプログラムの最後に、料金などの合計数を合計しました。次に、プログラムを通過した顧客の数を合計する必要があります。お客さんに定員がないので大変です。このプログラムは while ループで実行され、顧客の総数は完全にユーザー次第です。顧客の合計金額を合計するにはどうすればよいですか?

先頭に追加numCustomers = 0します。

また、これを変更します。

while nextcustomer != "no":
    amtgiven = 0

これに：

while nextcustomer != "no":
    numCustomers += 1
    amtgiven = 0

最後に、これを追加します。

print 'total customers:', numCustomers
