A library to calculate python dependency graphs.
Importlab is a library for Python that automatically infers dependencies and calculates a dependency graph. It can perform dependency ordering of a set of files, including cycle detection.
Importlab’s main use case is to work with static analysis tools that process one file at a time, ensuring that a file’s dependencies are analysed before it is.
(This is not an official Google product.)
Importlab can be installed from pip
pip install importlab

Importlab is primarily intended to be used as a library. It takes one or more python files as arguments, and generates an import graph, typically used to process files in dependency order.
It is currently integrated into pytype
Importlab ships with a small command-line tool, also called importlab, which can display some information about a project’s import graph.
usage: importlab [-h] [--tree] [--unresolved] [filename [filename ...]] positional arguments: filename input file(s) optional arguments: -h, --help show this help message and exit --tree Display import tree. --unresolved Display unresolved dependencies.
- Makefile generation, to take advantage of make’s incremental update and parallel execution features
- Integration with other static analysis tools
