PEP 8 (https://www.python.org/dev/peps/pep-0008), the officially recommended style guide for Python code, is generally well regarded and widely followed. Having a consistent style, whatever it is, makes your code more readable. You can of course have your own house style, but using the same style as most other Pythonistas for new code helps other people read your code. I recommend following PEP 8 as much as possible. > > For instance, the conventions suggest that > > if x>y : > pass > > should be written > if x > y: > pass > > Personally, I like seeing a space before the colon (:).

Spaces inside brackets, especially in list comprehensions, may be more common. Personally I've found that my preferred tool, the Anaconda plugin for Sublime Text, sometime gets PEP 8 operator spacing wrong, and complains operators without spaces even where PEP8 explicitly recommends not using spaces. Read PEP 8, follow it if possible, but use your best judgement. Readability is important, blindly following your IDE's advice not so much. -- Thomas > > If you are teaching beginning students, do you expect them to try to > follow these sorts of conventions?
