Python允许单词输入

Question

我无法让用户输入除整数之外的任何内容，因为这样做会导致程序崩溃而不会打印我想要的文本。

这是终端中的程序。

Answer 1

你需要对python 2.x使用raw_input（）

guess = raw_input()

还有代码

elif: #Need help here!

语法无效 - 它需要条件子句。但是看看你的代码，你可以将“elif：”删除到“break”，因为它只是复制了它下面的内容。

Answer 2

第6行＆amp;你应该使用

print 'No its '+str(ans)

Answer 3

from random import randint
import sys

# Python version compatibility shim
if sys.hexversion < 0x3000000:
    # Python 2.x
    inp = raw_input
    rng = xrange
else:
    # Python 3.x
    inp = input
    rng = range

TRIES = 10

def main():
    print("Welcome to the Math Challenge!")
    correct = 0
    for m in rng(1, TRIES + 1):
        n = randint(1, 16)
        answer = m * n
        guess = inp("What is {} x {}? ".format(m, n))
        try:
            guess = int(guess)
            if guess == answer:
                print("That's right")
                correct += 1
            else:
                print("Sorry, it's actually {}".format(answer))
        except ValueError:
            # guess is not an int value
            guess = guess.strip().lower()
            if guess == "skip":
                print("Skipping...")
                continue
            elif guess == "stop":
                print("Stopping...")
                break
    print("You got {} correct out of {}!".format(correct, TRIES))

if __name__ == "__main__":
    main()
