Is there a built-in function in Python that would replace (or remove, whatever) the extension of a filename (if it has one)?
Example:
print replace_extension('/home/user/somefile.txt', '.jpg')
In my example: /home/user/somefile.txt
would become /home/user/somefile.jpg
I don't know if it matters, but I need this for a SCons module I'm writing. (So perhaps there is some SCons specific function I can use ?)
I'd like something clean. Doing a simple string replacement of all occurrences of .txt
within the string is obviously not clean. (This would fail if my filename is somefile.txt.txt.txt
)
Try os.path.splitext it should do what you want.
import os
print os.path.splitext('/home/user/somefile.txt')[0]+'.jpg' # /home/user/somefile.jpg
os.path.splitext('/home/user/somefile.txt') # returns ('/home/user/somefile', '.txt')
