次の関数に行く前に完全に印刷されていないリスト

Question

私は教室外で学習するために、自動販売機をPythonで作成しようとしています。私は現在、自動販売機の飲み物や軽食のオプションを印刷しようとしています。関数choose（）を追加する前に、リストオプションを完全に出力しました。選択（）関数を追加すると、リストの最初の項目だけが出力されます。

import time 
drinkPairs=[("Apple Juice", 1.50), ("Monster", 3.75), ("Red Bull", 3.75), ("Sprite", 2.00), ("Water", 1.00)] 
drinkDict, drinkPrice = zip(*drinkPairs) 

snackPairs=[('Pringles', 3.50), ('Doritos', 3.15), ('Chocolate Donuts', 2.50), ('Honey Bun', 3.75), ('Cinnamon Roll', 3.50)] 
snackDict, snackPrice = zip(*snackPairs) 


def select(): 
    if 'drink' in answer.lower(): 
     drink() 
    elif 'snack' in answer.lower(): 
     snack() 
    else: 
     error() 
#give selection of items and costs of items 
def drink(): 
    print('Here are the drink options:\n') 
    for i, p in enumerate(drinkDict): 
     print('{}: ${:.2f}\n'.format(p,drinkPrice[i])) 
     #choose() 
def snack():

Answer 1

for i, p in enumerate(snackDict): 
     print('{}: ${:.2f}\n'.format(p,snackPrice[i])) 
     choose() # <===================================== problem is likely here 

私はchoose()は、ユーザーが項目のいずれかを選択することができますことを前提としています。選択を求めるプロンプトが表示される前にすべてを印刷したい場合は、choose()をインデントレベルの1つに移動してください。今はfor-loop内にあるので、1つの項目を印刷してプロンプトを表示します。移動すると、すべての項目が印刷され、プロンプトが表示されます。

for i, p in enumerate(snackDict): 
     print('{}: ${:.2f}\n'.format(p,snackPrice[i])) 
    choose() # removed one indent. now the choice will happen *after* the loop
