python乘法测验无效的语法

Question

我有这个 python 乘法测验。

import random

score = 0
continue = True
while continue:
    a = random.randint(1, 12)
    b = random.randint(1, 12)
    product = a * b
    guess = int(input('What is '+str(a)+' times '+str(b)+'? (press "q" to quit):'))
    if guess == 'q':
        continue = False
    if guess != product:
        print('Sorry, this is wrong. It should be '+str(product)+'.')
        continue = False
    if guess == product:
        print('Good job. You got it right.')

print('Thanks for playing! You scored '+str(score)+'.')

一直说 SyntaxError: invalid syntax当我尝试在 continue = True 行运行它时.

添加之前 continue查询，它工作正常:

import random

score = 0
while True:
    a = random.randint(1, 12)
    b = random.randint(1, 12)
    product = a * b
    guess = int(input('What is '+str(a)+' times '+str(b)+'? (press "q" to quit):'))
    if guess == 'q':
        break
    if guess != product:
        print('Sorry, this is wrong. It should be '+str(product)+'.')
    if guess == product:
        print('Good job. You got it right.')

print('Thanks for playing! You scored '+str(score)+'.')

我不确定这行 continue = True 有什么问题.据我所知，这是分配 True到变量 continue .请帮忙!

Answer 1

continue是一个python关键字，如if , else , True , break等，因此您无法为其分配值。如果你想使用这个名字，试试 continue_ (来自pep8)。

还有 continue_修复进入 'q'会导致异常，因为 python 试图做 int('q') ，这不起作用。

您没有在函数中增加分数，因此添加 score += 1如果正确会有所帮助。

import random


score = 0
continue_ = True
while continue_:
    a = random.randint(1, 12)
    b = random.randint(1, 12)
    product = a * b
    guess = input('What is '+str(a)+' times '+str(b)+'? (press "q" to quit):')
    if guess == 'q':
        break
    if int(guess) != product:
        print('Sorry, this is wrong. It should be '+str(product)+'.')
        continue_ = False
    if int(guess) == product:
        print('Good job. You got it right.')
        score += 1

print('Thanks for playing! You scored '+str(score)+'.')

例如将输出

What is 6 times 7? (press "q" to quit):42
Good job. You got it right.
What is 10 times 7? (press "q" to quit):70
Good job. You got it right.
What is 8 times 7? (press "q" to quit):56
Good job. You got it right.
What is 9 times 10? (press "q" to quit):90
Good job. You got it right.
What is 2 times 12? (press "q" to quit):24
Good job. You got it right.
What is 12 times 3? (press "q" to quit):36
Good job. You got it right.
What is 11 times 6? (press "q" to quit):66
Good job. You got it right.
What is 11 times 7? (press "q" to quit):q
Thanks for playing! You scored 8.
