Question

我是一名初学程序员，学习Python（使用版本2.7.4）并且我已经制作了这个数字猜谜游戏。到目前为止，这是我的代码：

import random
name = raw_input("Hi there! What\'s your name?\n")
print "Well, " + name + ", I am thinking of a number between 1 and 100"
number = random.randint(1,100)
guess = int(raw_input("Take a guess:\n"))


count = 1

while guess != number:    
    if guess < number:
        print "Sorry, your guess is too low."                 
    if guess > number:
        print "Sorry, your guess is too high."
    count += 1
    guess = int(raw_input("Take another guess\n"))

print "Good job, %s! You guessed my number in %d guesses!" % (name ,count)

如何提醒玩家他们之前曾猜到的猜测？
如何确保播放器只能输入数字作为猜测？我很难过。谢谢！

Answer 1

对于第一个问题，请使用set跟踪以前的输入值：

seen = set()
while guess != number:    
    if guess < number:
        print "Sorry, your guess is too low."                 
    if guess > number:
        print "Sorry, your guess is too high."
    count += 1
    while True:
        guess = int(raw_input("Take another guess\n"))
        if guess in seen:
            print "Oops, you have guess than one before"
            continue
        else:
            seen.add(guess)
            break

对于第二个问题，您可以使用isinstance()函数，但没有太多需要。 int()函数将为您检查输入，如果没有得到整数输入，将引发异常。如果您愿意，可以捕获该异常并添加一条很好的错误消息：

    try:
        guess = int(raw_input("Take another guess\n"))
    except ValueError:
        print "Sorry, I expected an integer"

Answer 2

问题一的答案列出了一个清单：

while run:
    geusslist = []
    number = raw_input("Make A Geuss")
    geusslist.extend((number))

if print_nums:
    print "You Have Guessed:"
    print geusslist

如果此代码已运行并且播放器猜测10,20,30,40,50应返回

>>> You Have Geussed:
>>> [10, 20, 30, 40, 50]

关于问题二我认为＆＃39; Raymond Hettinger＆＃39;上面回答的非常好。
