如何重启猜数字游戏

Question

我正在使用 Python 2.7.1 这个版本。

我想让游戏可以根据用户的输入来重新开始，这样用户就可以选择重新开始，而不是直接退出游戏再重新打开。有人能帮我想想办法吗？谢谢！

import random

the_number = random.randrange(10)+1

tries = 0
valid = False
while valid == False:
    guess = raw_input("\nTake a guess: ")
    tries += 1
    if guess.isdigit():
        guess = int(guess)
        if guess >= 1 and guess <= 10:
            if guess < the_number:
                print "Your guessed too low"
            elif guess > the_number:
                print "Your guessed too high"
            elif tries <= 3 and guess == the_number:
                print "\n\t\tCongratulations!"
                print "You only took",tries,"tries!"
                break
            else:
                print "\nYou guessed it! The number was", the_number,"\n"
                print "you took",tries,"tries!"
                break
        else:
            print "Sorry, only between number 1 to 10"
    else:
        print "Error,enter a numeric guess"
        print "Only between number 1 to 10"
    if tries == 3 and guess != the_number:
        print "\nYou didn't guess the number in 3 tries, but you still can continue"
        continue
    while tries > 3 and guess != the_number:
        q = raw_input("\nGive up??\t(yes/no)")
        q = q.lower()
        if (q != "yes") and (q != "no"):
            print "Only yes or no"
            continue
        if q != "no":
            print "The number is", the_number
            valid = True
            break
        else:
            break

Answer 1

while True:
    play_guessing_game()
    user = raw_input("Play again? (Y/n) ")
    again = "yes".startswith(user.strip().lower())
    if not again:
        break

... 这里的 "yes".startswith() 这一部分的意思是，它可以接受像 'Ye'、' yeS' 这样的输入，或者你只要按一下回车键也可以。

Answer 2

添加一个变量，给它起个名字，比如叫 continue，然后把它的初始值设为 true。接着，把你的整个代码放在一个 while(continue) 循环里。在循环的最后，打印出 play again?，然后接受用户的输入，根据他们的回答来设置 continue 的值。

Answer 3

把你现在的代码放到一个函数里，比如叫 play_game 或者其他你喜欢的名字。然后写一个循环，让这个函数一直运行，直到用户觉得够了为止。比如：

def global_thermonuclear_war():
    print "Boom!"

while raw_input("Shall we play a game? [y|n] ") == 'y':
    global_thermonuclear_war()
