   ls --help
   

PyPi Lifecycle

Authenticaion

File name: ~/.pypirc

[pypi]
  username = __token__
  password = <PUT THE TOKEN HERE>

Generate source and binary distribution

python setup.py sdist bdist_wheel

Test locally

Install locally

pip install -e .

Uploading to PyPi

Upload to PyPi:

python -m twine upload dist/* --verbose

Git push

git push -u origin main

Git Configuration

There are 3 levels of git config; project, global and system. Ref

1. project: Project configs are only available for the current project and stored in .git/config in the project's directory.
2. global: Global configs are available for all projects for the current user and stored in ~/.gitconfig.
3. system: System configs are available for all the users/projects and stored in /etc/gitconfig. Create a project specific config, you have to execute this under the project's directory:

$ git config user.name "Mahesh Patil"
$ git config user.email "cpuinfo10@gmail.com"

Create a global config:

$ git config --global user.name "Mahesh Patil"
$ git config --global user.email "cpuinfo10@gmail.com"

Create a system config:

$ git config --system user.name "Mahesh Patil"
$ git config --system user.email "cpuinfo10@gmail.com

Design Notes

Handling CLI arguments, options and flags

Three popular options Ref for handling CLI arguments, options and flags are:

1. sys.argv
2. argparse
3. click
