For a brief period, Python 2.6 was supported in Hypothesis for Python. Because Python 2.6 has been end of lifed for some time, I decided this wasn’t a priority and support was dropped in Hypothesis 2.0.
I’ve now added it back, but under a more restrictive license.
If you want to use Hypothesis on Python 2.6, you can now do so by installing the hypothesislegacysupport package. This will allow you to run Hypothesis on Python 2.6.
