As part of Project Thoth, we are accumulating knowledge to help Python developers create healthy applications. This tool was developed by Project Thoth, part of the Artificial Intelligence Center of Excellence group (AICoE). The project source files are hosted on GitHub in Project Thoth's invectio repository. To install it, just enter the following: $ pip install invectio Invectio is available as a Python package on PyPI. Like the whatuses subcommand, the whatprovides subcommand can work on directories to inspect all the Python source code present in a directory. Running invectio whatprovides gives insights about symbols provided by the module: $ invectio whatprovides module.py Consider the following Python source code: CONST = 42 invectio whatprovidesĪnother invectio subcommand extracts information about functions, classes, and constants available in the source code.

The tool can also take a directory as an argument and display the symbols from all the Python source files in that directory.

The output is in JSON format: $ invectio whatuses test.py Running invectio whatuses extracts information about symbols used from other modules, the use of built-in symbols, and Python standard library symbols. Let's consider a simple Flask application: import flask The first command available in invectio extracts information about symbols used in the source files. Because this task is widely applicable in many situations, the Project Thoth team has extracted the logic into a simple application that displays the symbols used or exported by source code. This capability, along with other parts of the standard library, allows you to examine Python source code and extract information about symbols used or provided. The Python standard library contains a module called Abstract Syntax Trees ( ast), with routines to parse Python source code and access it within a program. As the name suggests, this small tool can extract information about imports as well as information about what users can import from Python modules. What library symbols does a Python source code file use? And what symbols does it provide to its users? A simple tool called invectio can provide this information based on static source code analysis.
