Let me introduce you to the world of count lines of code in directory register. There may be cases where you want to delete empty folders recursively. The standard utility modules for Python include this module. They can be compressed using gzip, bzip2, and lzma compression methods. Next is the call to .iterdir() to get a list of all files and directories in my_directory. PythonGILPython"""Python" . Passing recursive=True as an argument to .iglob() makes it search for .py files in the current directory and any subdirectories. After reading or writing to the archive, it must be closed to free up system resources. Trying to open or extract files from a closed ZipFile object will result in an error.

For each directory in the tree rooted at directory top (including top itself), it yields a 3-tuple (dirpath, dirnames, filenames). In versions of Python prior to Python 3, os.listdir() is the method to use to get a directory listing: os.listdir() returns a Python list containing the names of the files and subdirectories in the directory given by the path argument: A directory listing like that isnt easy to read. The next line prints a directory listing showing that the current directory now includes the extracted file in addition to the original archive. >>> list_ = os.listdir ("path/to/Data") >>> list_ os and pathlib include functions for creating directories. To convert the values returned by st_mtime for display purposes, you could write a helper function to convert the seconds into a datetime object: This will first get a list of files in my_directory and their attributes and then call convert_date() to convert each files last modified time into a human readable form. If you need to create directories with different permissions call .makedirs() and pass in the mode you would like the directories to be created in: This creates the 2018/10/05 directory structure and gives the owner and group users read, write, and execute permissions.
