需要帮助添加循环以重新启动Python中的程序 [英] Need help adding a loop to restart program in Python

问题描述

到目前为止，这就是我所拥有的.

So far this is what I have got.

import random

answer1=("Absolutely!")
answer2=("No way Pedro!")
answer3=("Go for it tiger.")
answer4=("There's different ways to do this.")
answer5=("Definitely not")

print("Welcome to the Magic 8 Ball game-use it to answer your questions...")

questio = input("Ask me for any advice and I'll help you out. Type in your question and then press Enter for an answer")

print("Shaking... \n" * 4) 

choice=random.randint(1,5)

if choice == 1:
    answer=answer1
elif choice == 2:
    answer=answer2
elif choice == 3:
      answer=answer3
elif choice == 4:
      answer=answer4

elif choice == 5:
      answer=answer5


print(answer)

restart = input("Would you like to try again?")

if restart == "yes" or "y":

现在我需要为此添加一个循环，以便在完成后显示您是否想再试一次?".输入是"后，程序将从顶部重新开始.

now I need to add a loop to this so after its done it displays "Would you like to try again?". After entering yes the program starts again from the top.

推荐答案

尝试将这样的循环添加到您的代码中:

Try adding a loop like this to your code:

restart = ''

while restart.upper() not in ['NO', 'N', 'EXIT']:
    # ...  
    # Your code here
    # ...

    restart = input("Would you like to try again?")

这实际上是将重启初始化为空字符串.然后，循环仅在restart != 'NO'时开始.在循环结束时，我们从用户那里获得了restart的新值，因此，如果他们说'no'或'n'，则循环不会再次开始.

This is essentially initializing restart as an empty string. Then the loop is only going to start while restart != 'NO'. At the end of the loop we're getting a new value from the user for restart so that if they say 'no' or 'n' the loop won't start again.

还有许多其他方法可以执行此操作，例如，可以检查用户是否输入了肯定答案('yes'或'y')，或者如果他们说break >.

There are lots of other ways to do this, such as the inverse where you could check to see if the user entered a positive answer ('yes' or 'y') or putting a break if they say 'no'.

希望这可以帮助您入门.

Hopefully this gets you started.
