python運行方法後重新啓動程序

Question

我確定有一個noob問題。例如，假設我有一個看起來像這樣的程序。

def method1(): 
    #do something here 

def method2(): 
    #do something here 

#this is the menu 
menu=input("What would you like to do?\ntype 1 for method1 or 2 for method2: ") 
if(menu=="1"): 
    method1() 
if(menu=="2"): 
    method2() 

如何讓該菜單在方法結束而不是程序終止後再次出現？

我想我可以包住整個程序進入一個死循環，但感覺不對：P

Answer 1

while True: 
    #this is the menu 
    menu=input("What would you like to do?\ntype 1 for method1 or 2 for method2: ") 
    if(menu=="1"): 
     method1() 
    if(menu=="2"): 
     method2() 

如果死循環「感覺不對」，問自己何時爲什麼它應該結束。你應該有第三個輸入選項退出循環？然後加入：

if menu == "3": 
    break 

Answer 2

無限循環是這樣做雖然方式是這樣的：

running = true 

def method1(): 
    #do something here 

def method2(): 
    #do something here 

def stop(): 
    running = false 

while running: 
    #this is the menu 
    menu=input("What would you like to do?\ntype 1 for method1 or 2 for method2 (3 to stop): ") 
    if(menu=="1"): 
     method1() 
    if(menu=="2"): 
     method2() 
    if(menu=="3"): 
     stop()
