This is a Python Packaging Helper Environment that helps beginner's in python get acquainted with the concepts of Building,Packages and Managing them. This tutorial gives beginners a complete flow of how python packages are done in the industries.

Please do the following:

1. Create a new git repository with git-init(1). Commit as desired. If you're worried about losing any of the sample code that you're writing, create a new GitHub repository, skim git-remote(1), and push your code to your new GitHub repository.

2. Within this git repository, create the following directory structure:

   .
   ├── my_package
   │   └── tests.py
   └── setup.py
   

3. Read the unittest documentation from the beginning through section 26.4.2.0. (That is, read until section 26.4.2.1.) In addition, skim the list of methods exposed by unittest.TestCase.

4. Create a test case in tests.py. Within this test case, create one test method for each of the following assertions:

   • '0.1' is equal to '0.1'
   • '0.1' is less than '0.2'
   • '0.2' is greater than '0.10'

   Do not use the assertTrue method for these assertions. There are other, more targeted methods, as mentioned in step 3. Verify that the tests pass.

5. Read packaging and distributing projects. Feel free to skim the "setup() args" section.

6. Create a virtualenv using python3 -m venv ..., and activate it. Populate your setup.py with just enough information to be valid. Install your package into the virtualenv in "editable mode," e.g. with pip install --editable .. Change to an entirely different directory (e.g. with cd ~), and verify that you can execute tests with python -m unittest my_package.tests.

7. Add install_requires to setup.py, and depend on packaging. Verify that pip install --editable . pulls in the packaging library. You can verify this with pip freeze.

8. Add a new test case into the tests.py file. Within this test case, create one test method for each of the following assertions:

   • Version('0.1') is equal to Version('0.1')
   • Version('0.1') is less than Version('0.2')
   • Version('0.2') is less than Version('0.10')

   Do not use the assertTrue method for these assertions. There are other, more targeted methods, as mentioned in step 3. Verify that the tests pass.

9. Add extras_require to setup.py, and create a "dev" section that lists "pylint." See the docs for an example of how to do this. Verify that pip install --editable .[dev] pulls in pylint. You can verify this with pip freeze.

10. Execute pylint my_package. Fix all warnings.

11. Deactivate your virtualenv. Blow it away, e.g. with rm -rf path/to/virtualenv. Create a new one. Install your Python package into this virtualenv. Verify that you can move to a different directory and successfully execute the tests, e.g. with cd ~ && python -m unittest my_package.tests.

12. Once Done with managing the packages locally, The package can be distributed to the remote. This works by creating aPypI account first. Install twine pip install twine. Setting up the Build files using python setup.py sdist and pip install wheel followed by python setup.py bdist_wheel --universal. Then run the upload by using twine upload dist/*. for more infor refer docs

13. The above step is used for installing the package. However to install and make the packages available on import statements, use packages=setuptools.find_packages() in the setup.py file.
