that implicitly runs external commands. You n

Hello Eryk,
it is true that the most correct way to represent strings in Python 2 is by
dealing with Unicode but it is also true that the most common scenario in
both the stdlib and most third party libs is to return and deal with str
(bytes) instead, so this is why I decided to do the same in psut

Hello,
Trying to understand command:
[p for p in sys.path]
It prints array of paths. I suppose p becomes array of strings but what []
means in this statement?

This is called "list comprehension", and
paths = [p for p in sys.path if "foo" in p]

Generally, it's an inline form of writing a loop that returns a list. There are
other types as well.
