This article mainly introduces Python's simple calculation of the folder size method, which involves Python's related techniques for directory traversal and file computing, and has some reference value, for more information about how to calculate the folder size in Python, see the following example. Share it with you for your reference. The details are as follows:

Import OS, re "view all files in the folder and join the folder as the splicing function" def Look_File (path): for root, dirs, files in OS. walk (path, True): print root # main directory for item in files: # print OS in the main directory. path. join (root, item) "Calculate folder size" def FileSize (path): size = 0L for root, dirs, files in OS. walk (path, True): size + = sum ([OS. path. getsize (OS. path. join (root, name) for name in files]) # Add return sizeif _ name _ = '_ main _' to the file size in the directory __': look_File ("f: \ a") print FileSize ("f: \ ")

I hope this article will help you with Python programming.
