Yes because ``goset`` (I guess "goest" was a typo!?) has no option
`'-f '"%s %s" name addr' `. And you should decide if you want to split
the arguments yourself or if you want to use the shell. Mixing both
doesn't make much sense.
If *you* split the arguments, the call should look like this:
p = subprocess.Popen(['goset', '-f', ' "%s %s" name addr ', 'file_name'])
