Documentation available at Read the Docs

You can install the package from Pypi

Polling2 is a powerful python utility used to wait for a function to return a certain expected condition.

Some possible uses cases include:

  • Wait for API response to return with code 200
  • Wait for a file to exist (or not exist)
  • Wait for a thread lock on a resource to expire

Polling2 is handy for getting rid of all that duplicated polling-code. Often, applications require retrying until the correct response is returned. Why re-implement the ability to poll again and again? Use Polling2!

Polling2 is a fork of the original polling. It was forked when the original maintainer failed to respond to issues or PRs.

Polling2 is under active development. Would you like to see a particular feature? Ask and thou shall recieve.


pip install polling2

Development installation

# install lib, but use system links from the repo into sitepackages.
python develop
# install test dependenices.
python test
# run the tests
pytest tests


# This call will wait until the file exists, checking every 0.1 seconds and stopping after 3 seconds have elapsed
file_handle = polling2.poll(
    lambda: open('/tmp/myfile.txt'),

# Polling will return the value of your polling function, so you can now interact with it

There are more examples in the documentation.
