This series adds the Spyder IDE with all testing dependencies. The spyder package still has some rough edges: there is a warning about the parso version on startup, I had to disable the tests and there's a bug when importing numpy from a script (seems to be an issue with the numpy version). See
/tmp/guix-build-python-qtawesome-1.0.2.drv-0/QtAwesome-1.0.2/qtawesome/icon_browser.py:170: DeprecationWarning: an integer is required (got type float). Implicit conversion to integers using __int__ is deprecated, and may be removed in a future version of Python.
