Extracting extension from filename in Python
You can use the os.path.splitext() function from the os.path module in Python to extract the file extension from a filename.
Here's an example:
import os
filename = "example.txt"
extension = os.path.splitext(filename)[1]
print(extension)
This will output: .txt
Alternatively, you can use string slicing to extract the file extension.
import os
filename = "example.txt"
extension = filename[filename.index(".")+1:]
print(extension)
This will also output: .txt
