Cleaning strings with Regular Expressions

[sheffdog]

Hello,

 I often find myself cleaning up strings like the following:

    setAttr ".ftn" -type "string" /assets/chars/
    /boya/geo/textures/lod1/ppbhat.tga";

Using regular expressions, the best I can do so far is using the re.sub
command but it still takes two lines. Can I do this in one line? Or
should I be approaching this differently? All I want to end up with is
the file name "ppbhat.tga".

Python Code:
lines[indexC]=re.sub("[\s,\S,]*/", "", lines[indexC])
lines[indexC]=re.sub(".tga[\s,\S,]*", ".tga", lines[indexC])

Thanks for your time,
