That's a good idea, indeed. BTW, in this context I feel that

 if the(filename.endswith, ('.jpg','.jpeg','.gif','.png')):
    dosomething()

is more clear than 

 if any(filename.endswith, ('.jpg','.jpeg','.gif','.png')):
    dosomething()

which is confusing to me since it seems "any" is referred to "filename" 
whereas it is referred to the tuple elements.
