![]() ![]() While a variety of ways to structure your distribution package exist, I like the approach of placing Python code in a src directory. Now cd into that directory in your favorite terminal so that it is your current working directory. If you’re on Linux and installed using your OS package manager, you may have to install pip separately, see Installing pip/setuptools/wheel with Linux Package Managers. In this first article, we will set up a simple directory structure, write a Python module, configure the distribution package using setup.py, and install our new package in a virtual environment.Ĭreate a new directory for the project. py -m pip -version If you installed Python from source, with an installer from, or via Homebrewyou should already have pip. ![]() virtualenv works by creating a folder which holds all the necessary. Since Python 3.3, a subset of it has been integrated into the standard library under the venv module. virtualenv is a tool used to isolate Python projects and the associated packages. Add a robust and well-documented Python test framework like pytest, as introduced in Part 2, and you are golden. Virtualenv is a tool to set up your Python environments. The tools venv and pip, and pip's cousin dependency setuptools, are usually included in your Python distribution. A virtual environment is created on top of an existing Python installation, known as the virtual environment's 'base' Python, and may optionally be isolated from the packages in the base environment, so only those explicitly installed in the virtual environment are available. ![]() While Poetry and similar tools are being utilized more and more, I sometimes find that my Python development needs are satisfied by built-in Python features. python -m venv newenv activate the newly created environment by source newenv/bin/activate then install the required dependencies by pip install -r requirements.
