Get the current timestamp using a datetime module and store it in a separate variable.Please follow the below steps to append timestamp to file name: In Python, we can use the datetime module to work with dates and times. It is a standard convention to append a timestamp to file name to make them easy for storing and using later. In some applications, the data or logs will be stored in the files regularly in a fixed time interval. New_name = os.path.join(folder, new_base) # construct current name using file name and path # Checking if the file is present in the list Else, move to the next fileįiles_to_rename = If present, rename the file according to the desired convention.Check if the file is present in the list.Iterate through the list of files in the folder containing the files.Providing the list of files that needs to be renamed.The following are the steps we need to follow for renaming only a set of files inside a folder. While renaming files inside a folder, sometimes we may have to rename only a list of files, not all files. # Adding the count to the new file name and extensionĭestination = folder + "sales_" + str(count) + ".txt"Īfter renaming all files Renaming only a list of files in a folder

The following example demonstrates how to change the names of all the files from a directory. Iterate over the list using a loop to access each file one by one.It returns a list containing the names of the entries in the given directory. Get the list of files in a directory using os.listdir().We can rename multiple files in a folder using the os.rename() method by following the below steps. Consider a folder with four files with different names, and we wanted to rename all file names. Sometimes we need to rename all files from a directory. # if you don't' want to forcefully renameĭone renaming a file Rename Multiple Files in Python

New_name = r"E:\demos\files\reports\new_details.txt"Įxample 2: The same code could be wrapped in the try-except block as below. Old_name = r"E:\demos\files\reports\details.txt"

Write rename code in the try-except block.Įxample 1: Use os.path.isfile() import os.

Use os.path.isfile() in an if condition.

We can use the following two approaches to continue with renaming by removing the old file or stop without renaming it. It returns true if the destination file already exists. Use the isfile(‘path’) function before renaming a file. This can be avoided by wrapping our code in the try-except block. The os.rename() method raises the FileExistsError or OSError when the destination file name already exists. Rename a file after checking whether it exists

Note: If the dst already exists then the FileExistsError will be thrown in Windows and in the case of UNIX an OSError will be thrown. dst_dir_fd : (Optional) Destination file directory.src_dir_fd : (Optional) Source file directory.dst : A destination path for the newly renamed file.src : Path for the file that has to be renamed.The following are the parameters that we need to pass for the os.rename() method os.rename(src, dst, *, src_dir_fd=None, dst_dir_fd=None) This module comes under Python’s standard utility modules.

The os module provides functionalities for interacting with the operating systems. As shown in the example, we can rename a file in Python using the rename() method available in the os module.
