Python：运行 Python Unittest 时出现错误

Question

I am using following python version

$ python --version
Python 3.8.0

Python folder contains only following 4

IDLE (Python 3.8 32-bit)
Python 3.8 (32-bit)
Python 3.8 Manuals (32-bit)
Python 3.8 Module Docs (32-bit)

I have following unit test in test_sum_unittest.py

import unittest


class TestSum(unittest.TestCase):

    def test_sum(self):
        self.assertEqual(sum([1, 2, 3]), 6, "Should be 6")

    def test_sum_tuple(self):
        self.assertEqual(sum((1, 2, 2)), 6, "Should be 6")

if __name__ == '__main__':
    unittest.main()

Ran test with

python test_sum_unittest.py

The Error logs are as below

Traceback (most recent call last):
  File "test_sum_unittest.py", line 1, in <module>
    import unittest
  File "C:\Users\ali\AppData\Local\Programs\Python\Python38-32\lib\unittest\__init__.py", line 59, in <module>

    from token import *
  File "C:\Users\ali\Flasky\Automation\token.py", line 1, in <module>
    import requests
ModuleNotFoundError: No module named 'requests'

好的，我已经解决了这个问题，问题是在我的目录中有一个名为 token.py 的文件，我重命名了它，一切都开始工作了，现在地球上的人怎么会发现这可能是原因，但我很高兴它现在正在工作，谢谢大家。
