Atom, Anaconda & Co.

[snippsat]

with python you have IDLE, with anaconda spyder

Just as info Spyder do not ship with Anaconda anymore,it now ship with VS Code.

Me general tips:
Basic:
Python 3.6 and pip installation under Windows | Part-2
In part-2 you see cmder it's a lot better choice for daily use than Git bash.

Editor:
I would say VS Code(as posted before it also ship with Anaconda) is a better choice that Atom,
they both are multilanguage editors.
VS Code has better support for Python(as they also hired the creator of Python extension),my quick review.
VS Code Goes All In on Python

Very easy editor to use PyScripter, Thonny
All features PyCharm Free Community
