vulture - Find dead code

vulture finds unused classes, functions and variables in your code. This helps you cleanup and find errors in your programs. If you run it on both your library and test suite you can find untested code.

Due to Python's dynamic nature it is impossible to find all dead code for a static code analyzer like vulture, because it ignores scopes and scans only token names. Additionally some dynamic items that are not explicitly called in the code may be incorrectly reported as dead code.


  • Fast: Uses static code analysis
  • Lightweight: Only one module
  • Tested: Comes with a test suite
  • Complements pyflakes and has the same output syntax


  • vulture supports Python 2.6, 2.7 and 3.x

You can install, upgrade, uninstall with these commands:

$ sudo pip install vulture
$ sudo pip install --upgrade vulture
$ sudo pip uninstall vulture

pip can be installed with sudo apt-get install python-pip.


$ vulture --help

After you have found and deleted dead code, run vulture again, because it may discover more dead code.

Similar programs

  • vulture can be used together with pyflakes
  • The coverage module can find unused code more reliably, but requires all branches of the code to actually be run.

About the name

A vulture eats dead animals. A group of feeding vultures is called a wake. Simples.
