I got git-p4 from “git clone git://git.kernel.org/pub/scm/git/git.git git” I copied git-p4 from contrib/fast-import/git-p4 to /home/gyang/bin

I got SyntaxError  when I ran,

git-p4 clone //depot/Workshop

/home/gyang/bin/git-p4:161: Warning: 'yield' will become a reserved keyword in the future
  File "/user/svdc/pluo/bin/git-p4", line 161
    yield pattern
                ^
SyntaxError: invalid syntax

I opened the file, git-p4. There are three import lines. I am not python programmer. Maybe I missed something in python? I have python installed at /usr/local/bin/python

which python /usr/local/bin/python

vi git-p4 import optparse, sys, os, marshal, popen2, subprocess, shelve import tempfile, getopt, sha, os.path, time, platform import re

Can someone tell me what I missed?

Thanks.
