对于一个叫做M的常量，我创建了一个叫做constants的模块，并将M的值写入其中：

from random import choice
l1 = ['a',
      'ability',
      'able',
      'about',
      'above',
      'accept',
      'according'
      'account'
      'across',
      'act',
      'action',
      'activity',
      'actually',
      'add',
      'address',
      'administration',
      'admit',
      'adult',
      'affect',
      'The quick brown fox jumps over the lazy dog',
      'yes,'
      'Good Morning',
      'Good night',
      'Super Ball'
      ]
M = choice(l1)

我试着把它导入，但当我试着：

import datetime
import re

from constants import M

print('''
Welcome to Typing Practice!
We will give some random text.
You should type it again.
The time took will be printed.
Your time starts... NOW!!!
''')

print(f'You must enter {M}')
current_time = datetime.datetime.now()
h = input("")

n = re.compile(r'M')
errors = 0
for letter in M:
    if not n.match(h):
        errors += 1

time_now = datetime.datetime.now()
time_took = time_now - current_time
print("you took: ", time_took, "\n\\\\\\", "Errors:", errors)

我只是得到了你必须进入幕我进入幕，它说：\错误：3这可能意味着M正在更改！！
