I have a folder/tmp, how do I know the number of files in it
/tmp
import os DIR = '/tmp' result = [name for name in os.listdir(DIR)]
The result is all files and folders under DIR. How to get the number of files
Reference article: Issues related to Python file operations
>>> import os >>> DIR = '/tmp' >>> print len([name for name in os.listdir(DIR) if os.path.isfile(os.path.join(DIR, name))])
If you count the number of folders, useos.path.isdir(path)as a judgment statement.
os.path.isdir(path)
