A regular expression to do what you want:
 >>> s = 'setAttr ".ftn" -type "string" /assets/chars/boya/geo/textures/lod1/ppbhat.tga";'
 >>> s = re.sub(r".*/(.*\.tga).*", r"\1", s)
 >>> s
'ppbhat.tga'

Is a regular expression the best solution?
That depends on what else you need to do with your data file.
