This is called "list comprehension", and
paths = [p for p in sys.path if "foo" in p]
is roughly equivalent to
paths = []
for p in sys.path:
if "foo" in p:
paths.append(p)
Your original example
> [p for p in sys.path]
just copies the items from sys.path into a new list. This is usually done
with the more concise
list(sys.path)
