Steps to create local python package

References

• Publish your own python package

Prepare all files

• To create python package you'll need 4 things
  • solution folder : This contains all python script files related to your package
  • setup.py : file which contain package meta data
  • README :
  • LICENSE : package license
• refer this github repo : vidstream

• Sample setup.py file

  from setuptools import setup, find_packages
  import codecs
  import os
  
  here = os.path.abspath(os.path.dirname(__file__))
  
  with codecs.open(os.path.join(here, "README.md"), encoding="utf-8") as fh:
      long_description = "\n" + fh.read()
  
  VERSION = '0.0.13'
  DESCRIPTION = 'Streaming video data via networks'
  LONG_DESCRIPTION = 'A package that allows to build simple streams of video, audio and camera data.'
  
  # Setting up
  setup(
      name="vidstream",
      version=VERSION,
      author="NeuralNine (Florian Dedov)",
      author_email="<mail@neuralnine.com>",
      description=DESCRIPTION,
      long_description_content_type="text/markdown",
      long_description=long_description,
      packages=find_packages(),
      install_requires=['opencv-python', 'pyautogui', 'pyaudio'],
      keywords=['python', 'video', 'stream', 'video stream', 'camera stream', 'sockets'],
      classifiers=[
          "Development Status :: 1 - Planning",
          "Intended Audience :: Developers",
          "Programming Language :: Python :: 3",
          "Operating System :: Unix",
          "Operating System :: MacOS :: MacOS X",
          "Operating System :: Microsoft :: Windows",
      ]
  )
