It seems that the recaptcha-client package is no longer maintained.

• The latest released version (1.0.6) is from the year 2011;
• The project page does not mention which Python versions are supported
• The project is hosted on google code, which is discontinued, e.g. making it impossible to create an issue asking about which Python versions are supported.

I was able to successfully build with Python versions 3.3, 3.4, but not
3.5, 3.6.

Motivation for this change

The package was showing as broken on Hydra.

The package initially broke on a missing dependency on Crypto, but was broken even after that, e.g.

The package imports urllib2, but

The urllib2 module has been split across several modules in Python 3 named urllib.request and urllib.error. The 2to3 tool will automatically adapt imports when converting your sources to Python 3.
