IPython pdb


ipdb exports functions to access the IPython debugger, which features tab completion, syntax highlighting, better tracebacks, better introspection with the same interface as the pdb module.

Example usage:

import ipdb
ipdb.set_trace()'x[0] = 3')
result = ipdb.runcall(function, arg0, arg1, kwarg='foo')
result = ipdb.runeval('f(1,2) - 3')

The post-mortem function,, is equivalent to the magic function %debug.

If you install ipdb with a tool which supports setuptools entry points, an ipdb script is made for you. You can use it to debug your python 2 scripts like

$ bin/ipdb

And for python 3

$ bin/ipdb3

Alternatively with Python 2.7 only, you can also use

$ python -m ipdb

You can also enclose code with the with statement to launch ipdb if an exception is raised:

from ipdb import launch_ipdb_on_exception

with launch_ipdb_on_exception():


Context managers were introduced in Python 2.5. Adding a context manager implies dropping Python 2.4 support. Use ipdb==0.6 with 2.4.


Using from future import print_function for Python 3 compat implies dropping Python 2.5 support. Use ipdb<=0.8 with 2.5.

Pull requests should take care of updating the changelog HISTORY.txt.

Third-party support


Zope2 Products.PDBDebugMode uses ipdb, if available, in place of pdb.


iw.debug allows you to trigger an ipdb debugger on any published object of a Zope2 application.


ipdbplugin is a nose test runner plugin that also uses the IPython debugger instead of pdb. (It does not depend on ipdb anymore).

Something went wrong with that request. Please try again.
