Project description

Python Lodash

pylodash is collection utilities allow you working with arrays, maths, number and string

Installation

You can install the Pylodash from PyPI:

pip install pylodash

Pylodash is supported on Python 3.4 and above.

How to use methods

You can call the Pylodash in your own Python code, by importing the pylodash package:

>>> from pylodash import arrays as _
>>> _.chunk(['a', 'b' , 'c', 'd'], 2)
// => [['a', 'b'], ['c', 'd']]

Development Mode

Building Your Package

In development mode, pylodash need install packages below to build package:

- setuptools >= 38.6.0
- wheel >= 0.31.0
- twine >= 1.11.0

Run command to build package:

$ python3 setup.py sdist bdist_wheel

Testing Your Package

To check that your package description will render properly on PyPI, you can run twine check on the files created in dist:

$ twine check dist/*

Uploading Your Packages

To install package to develop environment, we can use command:

$ python3 setup.py develop

To upload package to testing environment before upload to PyPI, follow step (make sure you have an account registered):

$ twine upload --repository-url https://test.pypi.org/legacy/ dist/*

To publish your own package to PyPI, this final step is short:

$ twine upload dist/*

pip install Your Package

With your package uploaded to PyPI, you can install it with pip as well:

$ pip install pylodash

To run all test cases in package, you can run command below in folder package:

$ nose2

To export test coverage to html file, run step:

$ nose2 --with-coverage --coverage-report html
