Python Environment Utils

Python Environment Utils is a set of command line tools to provide information about the Python folder layout.

You might find these useful just to quickly check where the python executable or scripts directory is, or maybe you would like the information for use in a shell script.

These command line tools are simply wrappers around functions from sys and sysconfig. The command line tools will be installed in the Scripts directory for your environment if you install Python Environment Utils with pip.

Look for functions in sys and sysconfig that match the name of the command after removing the pye_ prefix (i.e. the command pye_prefix corresponds to the prefix function in sys.

Installation

Install the Python Environment Utils in each Python environment or virtual environment you wish to have the utils available in.

pip install pyenvutils

Implementation and List of Commands

A one line function for each command is in pyenvutils.py. pyproject.toml specifies the command and the Python function to execute when the command is issued from the command line.

Here is an excerpt from pyproject.toml showing how py_sysconfig and pye_scripts are implemented:

pye_sysconfig="sysconfig:_main"
pye_scripts ="pyenvutils.pyenvutils:scripts"

A tool called flit builds the python install package. When the package is installed with pip the command line programs will be installed in the scripts directory. After you install Python Environment Utils, you can run pye_scripts to locate the scripts directory.

In Windows PowerShell or in Bash run:

ls $(pye_scripts)

to see all the commands available in your Python installation.
