How to replace (or strip) an extension from a filename in Python?

Question

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_

For Python >= 3.4:

from pathlib import Path

filename = '/home/user/somefile.txt'

p = Path(filename)
new_filename = p.parent.joinpath(p.stem + '.jpg') # PosixPath('/home/user/somefile.jpg')
new_filename_str = str(new_filename) # '/home/user/somefile.jpg'
