Question

我正在python 3上创建一个程序。我有一个地方需要重启脚本。我怎么能这样做。

 #where i want to restart it
name= input("What do you want the main character to be called?")
gender = input("Are they a boy or girl?")

if gender == "boy":
    print("Lets get on with the story.")
elif gender == "girl":
    print("lets get on with the story.")
else:
    print("Sorry. You cant have that. Type boy or girl.")
    #restart the code from start

print("Press any key to exit")
input()

Answer 1

通过Python和boy上的两个条件来缩短代码的方式，这是一个关于编写非特定于girl的一般问题...

while True:
    name= input("What do you want the main character to be called?")
    gender = input("Are they a boy or girl?")

    if gender == "boy" or gender == "girl":
        print("Lets get on with the story.")
        break

    print("Sorry. You cant have that. Type boy or girl.")

print("Press any key to exit")
input()

Answer 2

简单但不好的解决方案，但你明白了。我相信，你可以做得更好。

while True:
    name= input("What do you want the main character to be called?")
    gender = input("Are they a boy or girl?")

    if gender == "boy":
        print("Lets get on with the story.")
    elif gender == "girl":
        print("lets get on with the story.")
    else:
        print("Sorry. You cant have that. Type boy or girl.")
        #restart the code from start

    restart = input("Would you like to restart the application?")
    if restart != "Y":
        print("Press any key to exit")
        input()
        break

在评估用户的输入后，不要让程序退出;相反，在循环中执行此操作。例如，一个甚至不使用函数的简单示例：

phrase = "hello, world"

while (input("Guess the phrase: ") != phrase):
    print("Incorrect.") //Evaluate the input here
print("Correct") // If the user is successful

这会输出以下内容，同时显示我的用户输入：

Guess the phrase: a guess
Incorrect.
Guess the phrase: another guess
Incorrect.
Guess the phrase: hello, world
Correct

或者你可以写两个单独的函数，它与上面相同（只是它被写成两个独立的函数）：

def game(phrase_to_guess):
return input("Guess the phrase: ") == phrase_to_guess

def main():
    phrase = "hello, world"
    while (not(game(phrase))):
        print("Incorrect.")
    print("Correct")

main()

希望这就是你要找的东西。
