That is not a syntax error. It is a type error. You cannot add a file 
object and a string object together.

Please inspect the value of dumpfile. You are treating it as if it were a 
string, but it looks like it is an open file object. I think that you 
probably expect this:

dumpfile = "path to some file"
tarfile.open(dumpfile + '.tar.gz','w:gz')


but what you actually have is probably something like this:


dumpfile = open("path to some file")
tarfile.open(dumpfile + '.tar.gz','w:gz')
