For example, on CPython 2.7.5 it will return "CPython/2.7.5". This function works best on CPython and PyPy: in particular, it probably doesn't work for Jython or IronPython. Future investigation should be done to work out the correct shape of the code for those platforms. tCPythontPyPys%s.%s.%stfinalttJythont IronPythonRs%s/%s( Rtpython_implementationtpython_versiontsystpypy_version_infotmajortminortmicrot releaselevelR (timplementationtimplementation_version((sF/usr/lib/python2.7/dist-packages/requests_toolbelt/utils/user_agent.pyR /s       (RR!R RR (((sF/usr/lib/python2.7/dist-packages/requests_toolbelt/utils/user_agent.pyts   )
