# Does the W&B client support Python 2?

The W\&B client library supported both Python 2.7 and Python 3 through version 0.10. Version 0.11 removed Python 2.7 support because of Python 2's end of life. On a Python 2.7 system, `pip install --upgrade wandb` installs only new releases of the 0.10.x series, which receives critical bug fixes and patches. The last version of the 0.10.x series that supports Python 2.7 is 0.10.33.
