Python程序循環

-3

我試圖在python中做一種終端克隆（只是爲了測試如果其他的和elif的聲明的力量）我想這樣做後，用戶輸入的東西進入終端，而且無論輸入的內容是否完整，都會返回到您可以輸入內容的位置。因此，可以說在用戶輸入Python程序循環

「幫助」

顯示的幫助菜單，然後終端輸入「終端~~ $」再次出現爲他們提供了輸入別的東西。

，或者如果用戶類型

「waejhgiuoahweioug」

終端狀態：「輸入無效」我希望它再回到終端輸入。（「終端~~ $」）我已經試過while循環，但是你似乎沒有工作。希望這是有道理的。這是到目前爲止我的代碼（我只有Tkinter的，所以我可以做的主循環（）我沒有試圖讓該終端窗口（雖然這將是酷）！）：

# Import wait settings and tkinter... we only need tkinter for the mainloop() setting, so the game doesn't close when it's finished # 
import time 
from tkinter import * 

print("Terminal V.1.0 Alpha") 
print("Type help for assistance with the terminal") 

# Input a command into the terminal! # 
terminalInput = input("Terminal~~$ ") 

# The inputs the terminal accepts # 

if terminalInput == "help": 
    time.sleep(1) 
    print("HELP") 
    print("Type: 'text = your_text' to make the terminal speak!") 
    terminalInput = input("Terminal~~$ ") 
    if terminalInput == "text = " + terminalInput: 
     print("Terminal:\\" + terminalInput) 

# Every input that the terminal does not accept # 
else: 
    print("Invalid Input: " + terminalInput) 

master = Tk()

那麼，究竟是什麼問題圍繞此循環？你到目前爲止的嘗試是什麼？你需要什麼'tkinter'？ –

使用while循環做到這一點： –

使用while循環不會這樣的：笑無效輸入：終端V.1.0 APLHA 用於與終端終端~~ $笑無效的輸入幫助鍵入help笑無效的輸入：笑無效輸入：笑無效輸入：笑無效輸入：笑無效輸入：笑無效輸入：笑無效輸入：笑無效輸入：笑無效輸入：笑無效輸入：笑無限.... –

試試這個：

while True: 
    # Input a command into the terminal! # 
    terminalInput = input("Terminal~~$ ") 

    # Indent rest of code so it's in the while block

感謝你們倆。當我將其添加到我的github中時，您將會獲得學分！ –

它的工作原理！非常感謝！ –

一個簡單的while循環可以幫助程序保持運行。

下面是代碼：

import time 

def help_loop(): 

    while True: 
      try: 
       print("Terminal V.1.0 Alpha") 
       print("Type help for assistance with the terminal") 

       # Input a command into the terminal! # 
       terminalInput = input("Terminal~~$ ") 

       print("Input: " + terminalInput) 

       if terminalInput.lower() == "help": 
        print("HELP") 
        print("Type: 'text = your_text' to make the terminal speak!") 
        try: 
         terminalInput = input("Terminal~~$ ") 
         if terminalInput == "text = " + terminalInput: 
          print("Terminal:\\" + terminalInput) 

        except Exception as ex: 
         print("Invalid Input: " + terminalInput) 
      except Exception as ex: 
       print("Invalid Input: " + terminalInput) 

def main(): 

    help_loop() 

if __name__ == '__main__': 
    main()

謝謝大家的幫助！這是我到目前爲止！請試試吧！

#Looking under the hood I see. Unless you know how to read Python, there are no secrets here ;)#
