如何重新啟動python 3腳本？

Question

我在python 3上創建一個程序。我有一個地方需要重啟腳本。 我怎樣才能做到這一點。

 #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

這是一個關於編程不是特定於Python的一般性問題...通過你可以用boy和girl的兩個條件來縮短代碼的方式......

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()

簡單但不好的解決方案，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

Answer 3

在評估用戶的輸入后，沒有程序退出; 相反，在循環中執行此操作。 例如，一個甚至不使用函數的簡單示例：

phrase = "hello, world"

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

這將輸出以下內容，同時顯示我的用戶輸入：

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

或者你可以寫兩個單獨的函數，它與上面相同（只是它被寫成兩個獨立的函數）：

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()
