To extract the extension from the filename in Python, we can use the os.path.splittext method.
For instance, we write:
import os
filename, file_extension = os.path.splitext('/path/to/somefile.ext')
print(file_extension)
We call os.path.splittext with the path string we want to extract the file extension from.
Then we take the file_extension from the returned tuple.
Therefore, file_extension is '.ext'.
