Getting error only one sdist may be uploaded

[sansupercool]

Why is this creating 2 tar.gz files, ‘ python setup.py sdist? I am trying to upload using twine upload -r pypitest dist/*.tar.gz and i get error saying

HTTPError: 400 Client Error: Only one sdist may be uploaded per release. for url: https://test.pypi.org/legacy/
ERROR: Job failed: exit code 1

Below is the setup.py file.
