Sorry, I've never used os.walk and didn't realize that it is a generator.
This will work for your purposes (and seems pretty fast compared to the
alternative):
file_count = len(os.walk(valid_path).next()[2])
The alternative is:
import os
import os.path
file_count = len([f for f in os.listdir('.') if os.path.isfile(f)])
