Write a pattern using wildcard characters.We can rename files that match a pattern using the following steps: – The glob module is used to find the files and folders whose names follow a specific pattern. The pattern matching is done using the glob module.
#Python os rename pdf#
For example, renaming only pdf files or renaming files containing a particular year in their name. Sometimes we wanted to rename only those files that match a specific pattern. Os.rename(old_name, new_name) Renaming files with a Pattern New_name = r"E:\demos\files\reports\sales" + current_timestamp + ".txt" Old_name = r"E:\demos\files\reports\sales.txt" import osĬurrent_timestamp = datetime.today().strftime('%d-%b-%Y')

Now, rename a file with a new name using a os.rename()Ĭonsider the following example where we are adding the timestamp in the “%d-%b-%Y” format.Append timestamp to file name by using the concatenation operator.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.

#Python os rename how to#
The following example demonstrates how to change the names of all the files from a directory.
#Python os rename code#
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
#Python os rename windows#
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.
