Question

我正在编写半径猜测游戏并且偶然发现了循环问题。这可能看起来像一个愚蠢的问题，但突破正确的位置？或者它应该是别的吗？

import random
import math
number = random.randint(1, 20)
area = math.pi * number**2
guessesTaken = 0
print '%.0f is the area' % (area)
print('Take a guess.')
guess = input()
guess = int(guess)
guessesTaken = guessesTaken + 1
while guessesTaken < 6:
    if guess < number:
        print('Your guess is too low.')
    if(guess > number):
        print('Your guess is too high.')





    if guess == number:
        guessesTaken = str(guessesTaken)
        print('Good job! You guessed my number in ' + guessesTaken + ' guesses!')
        break

    if guess != number:
        number = str(number)
        print('Nope. The number I was thinking of was ' + number)

您应该将最后两个if放在while循环之外。此外，在while内部，如果用户猜错了，您应该重新询问输入，否则guesses永远不会改变，您只需要永远循环。

如果要放置最大迭代次数，则应在循环内增加guessesTaken。

while guessesTaken < 6:
    if guess < number:
        print('Your guess is too low.')
    elif guess > number:
        print('Your guess is too high.')
    else:
        break

    guess = int(input('Try again: '))
    guessesTaken += 1

if guess == number:
    print('Good job! You guessed my number in {} guesses!'.format(guessesTaken))
else:
    print('Nope. The number I was thinking of was {}'.format(number))

无论如何，如果你知道你最多会有6次迭代，那么你应该只使用for循环：

for _ in range(6):  # loop 6 times
    if guess < number:
        print('Your guess is too low.')
    elif guess > number:
        print('Your guess is too high.')
    else:
        break

    guess = int(input('Try again: '))
