Example analysis of Python module production method

This article describes the method of making Python modules. Share it for your reference, as follows:

1 Purpose

Use the installation of the framework into the python environment and call it as a third-party module.

2 Step 1: Completed writing

The following code is equivalent to a template. Just change the name field and change it to the corresponding module name that needs to be installed. For example, here is: py_plus

Put the file in the same directory as py_plus

from  import dirname, join
# from  import parse_requirements
from setuptools import (
  find_packages,
  setup,
)
def parse_requirements(filename):
  """ load requirements from a pip requirements file """
  lineiter = (() for line in open(filename))
  return [line for line in lineiter if line and not ("#")]
with open(join(dirname(__file__), './'), 'rb') as f:
  version = ().decode('ascii').strip()
setup(
  name='py-plus', # Module name  version=version,
  description='A mini web framework', # describe  packages=find_packages(exclude=[]),
  author='xx',
  author_email='your@',
  license='Apache License v2',
  package_data={'': ['*.*']},
  url='#',
  install_requires=parse_requirements(""), # The required operating environment  zip_safe=False,
  classifiers=[
    'Programming Language :: Python',
    'Operating System :: Microsoft :: Windows',
    'Operating System :: Unix',
    'Programming Language :: Python :: 2.7',
    'Programming Language :: Python :: 3.4',
    'Programming Language :: Python :: 3.5',
    'Programming Language :: Python :: 3.6',
  ],
)

Note: There may be an error in the above code that requires additional installation of package modules and update setuptools

• pip install packaging
• pip install --upgrade setuptools

It may not exist, the corresponding one can be:

def parse_requirements(filename):
  """ load requirements from a pip requirements file """
  lineiter = (() for line in open(filename))
  return [line for line in lineiter if line and not ("#")]

3 Step 2: Completed writing

Function:

• State the modules and versions supported by the dependent environment

use:

• Use in
• Placed in a directory of the same level

requests>=2.18.4
six>=1.11.0

4 Step 3: Completed writing

Function:

• Indicate the current version, a qualified module must have the corresponding version number

use:

• Use in
• Placed in a directory of the same level

1.0

5 Step 4: Execute the installation command

step:

1. Switch to the corresponding python virtual environment
2. Switch to the directory
3. Execute in terminalpython install
