If the user does not have permission to delete the file, a PermissionError is raised. Next is the call to .iterdir() to get a list of all files and directories in my_directory. r opens the file in read only mode. You can also use the pathlib module to get the file name. Using fnmatch.fnmatch(), you could do it this way: Here, you print only the names of files that match the data_*_backup.txt pattern.

You can read more about it here. For example, to create a group of directories like 2018/10/05, all you have to do is the following: This will create a nested directory structure that contains the folders 2018, 10, and 05: .makedirs() creates directories with default permissions. Since theres no path specified, .extract() extracts file1.py to the current directory. The following example shows how to retrieve more details about archived files in a Python REPL. Example 1: python script to read all file names in a folder import os def get_filepaths (directory): """ This function will generate the file names in a directory tree by walking the tree either top-down or bottom-up. The filecmp module defines functions to compare files and directories, with various optional time/correctness trade-offs. If the directory isnt empty, an error message is printed to the screen: Alternatively, you can use pathlib to delete directories: Here, you create a Path object that points to the directory to be deleted. Running the program above produces the following: pathlib contains similar methods for making flexible file listings. pathlib was first introduced in Python 3.4 and is a great addition to Python that provides an object oriented interface to the filesystem. import os list_files = os.listdir () for file_name in list_files: print (file_name) Once you get the list of file names, you can perform different file operations like reading, writing and deleting files.
