Loop through all CSV files in a folder

I'm trying to loop through only the csv files in a folder that contains many kinds of files and many folders, I just want it to list all of the .csv files in this folder.

Here's what I mean:

import os, syspath = "path/to/dir"dirs = os.listdir(path)for file in dirs:    if file == '*.csv':        print file

I know there is no wildcard variable in python, but is there a way of doing this?
