How to exclude .DS_Store from file count?

Question

I'm trying to get the file count in a given directoy using python, but I'd like to exclude .DS_Store files.

How can that be done?

count = len([name for name in os.listdir(DIR)])

You should probably exclude all "hidden" files - `if not name.startswith('.')`. — jonrsharpe, Aug 11 '15 at 13:57
I don't think that's necessary, the answers you already have tell you how to include a conditional filter within a list comprehension. — jonrsharpe, Aug 11 '15 at 13:58

count = len([name for name in os.listdir(DIR) if name != ".DS_Store"])

Or to exclude all hidden files, like jonrsharpe suggested:

count = len([name for name in os.listdir(DIR) if name.startswith(".")])

You can use an if within your list comprehension :

count = len([name for name in os.listdir(DIR) if name !='.DS_Store'])

Or if you don't want a specific format you can use str.endswith :

count = len([name for name in os.listdir(DIR) if if not name.endswith('DS_Store')])
