Setting file path for Windows in IPython

Question

I am trying to set a path in Python to a folder, but I can't seem to get (PATH) to work. It works when I write out the path. Any ideas?

PATH = "data/dogscats"
sz = 224 
print(PATH)
#!dir /b "data/dogscats" <---- THIS WORKS
!dir /b (PATH)  <------ THIS DOESN'T

data/dogscats

FILE NOT FOUND

What was it? If your question is solved, it would be awesome if you could document that here, so that others can learn from it as well. See stackoverflow.com/help/someone-answers — jotaen

@jotaen, I speculated about a possible answer in a comment. After Joe confirmed that it worked, I edited the question title and tags to to add IPython and moved my comment to an answer. — Eryk Sun

!dir /b "$PATH" should do what you want, or use an expression such as !dir /b {'"%s"' % PATH}. See the IPython reference for more information. Note that because the path uses forward slash as a separator, it has to be quoted in Windows CMD in order to disambiguate the separator from a "/" option.
