Python: I am getting Errors while running Python Unittest

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

    import requests
ModuleNotFoundError: No module named 'requests'
