How to get file extension in Python?
In Python, we can extract the file extension using either of the two different approaches discussed below –
Method 1: Using Python os module splitext() function
This function splits the file path string into file name and file extension into a pair of root and extension such that when both are added then we can retrieve the file path again (file_name + extension = path). This function is preferred to use when the OS module is being used already.
('my_file', '.txt') File Name: my_file File Extension: .txt
Method 2: Using Pathlib module
pathlib.Path().suffix method of the Pathlib module can be used to extract the extension of the file path. This method is preferred for an object-oriented approach.
File Extension: .txt
