Python - 重用菜單上的用戶輸入

Question

實現此目的的最佳方式是什麼 - 在菜單上重用用戶輸入？ 這裏是我下面的示例代碼：

def input(): 
    user = raw_input('user: ') 
    passwd = getpass.getpass('passwd: ') 
    return (user,passwd) 

def function1(): 
    user, passwd, vcenter = input() 
do something 

def function2(): 
    user, passwd, vcenter = input() 
do something 

def function3(): 
    user, passwd, vcenter = input()  
    do something 

def main(): 
    while True: 
     if choice == 1: 
      function1() 
     elif choice == 2: 
      function2() 
     elif choice == 3: 
      function3() 
     else: 
      print 'Choose from the options only!' 
     break 

Answer 1

我覺得我得到你的意思，你要使用的輸入（）曾經在while循環，而不是重複調用它的每一個功能。如果是的話，我建議這個解決方案：

def input(): 
    user = raw_input('user: ') 
    passwd = getpass.getpass('passwd: ') 
    return (user,passwd) 

def function1(param): 
    user, passwd = param 
    do something 

def function2(param): 
    user, passwd = param 
    do something 

def function3(param): 
    user, passwd = param 
    do something 

def main(): 
    while True: 
     if choice in [1,2,3]: 
      param = input() 
     if choice == 1: 
      function1(param) 
     elif choice == 2: 
      function2(param) 
     elif choice == 3: 
      function3(param) 
     else: 
      print 'Choose from the options only (1, 2, 3): ' 
     break 

希望這可以幫助。
