Unit testing

[mp3909]

I have a file called

1

calc.py

and

1	test_calc.py

in my file called

1	test_calc.py

I have written:

1 2 3 4 5 6 7 8

import unittest import calc   class TestCalc(unittest.TestCase):       def test_add(self):         result=calc.add(10,5)         self.assertEqual(result,15)

When I try to run this file I get the following error in my interactive shell:

1 2 3 4 5 6 7 8 9 10 11

RESTART: C:/Users/sushi/AppData/Local/Programs/Python/Python36-32/test_calc.py Traceback (most recent call last):   File "C:/Users/sushi/AppData/Local/Programs/Python/Python36-32/test_calc.py", line 1, in <module>     import unittest   File "C:\Users\sushi\AppData\Local\Programs\Python\Python36-32\lib\unittest\__init__.py", line 59, in <module>     from .case import (TestCase, FunctionTestCase, SkipTest, skip, skipIf,   File "C:\Users\sushi\AppData\Local\Programs\Python\Python36-32\lib\unittest\case.py", line 7, in <module>     import pprint   File "C:/Users/sushi/AppData/Local/Programs/Python/Python36-32\pprint.py", line 7, in <module>     print(pprint.pformat(count)) AttributeError: module 'pprint' has no attribute 'pformat'

Why is this happening?

Did you write this file called pprint.py?

File "C:/Users/sushi/AppData/Local/Programs/Python/Python36-32\pprint.py", line 7, in <module>

By naming this file a name that is used in the standard library, your module is being used instead. More info here under "Naming your scripts and directories"
