Embed pickle (or arbitrary) data in python script

Question

In Perl, the interpreter kind of stops when it encounters a line with

__END__

in it. This is often used to embed arbitrary data at the end

Answer 1

I made this code. You run something like python comp.py foofile.tar.gz, and it creates decomp.py, with foofile.tar.gz's contents embedded in it. I don't think this is really portable with windows because of the Popen though.

import base64
import sys
import subprocess

inf = open(sys.argv[1],"r+b").read()
outs = base64.b64encode(inf)

decomppy = '''#!/usr/bin/python
import base64

def decomp(data):
    fname = "%s"
    outf = open(fname,"w+b")
    outf.write(base64.b64decode(data))
    outf.close()

    # You can put the rest of your code here.
    #Like this, to unzip an archive
    #import subprocess
    #subprocess.Popen("tar xzf " + fname, shell=True)
    #subprocess.Popen("rm " + fname, shell=True)
''' %(sys.argv[1])

taildata = '''uudata = """%s"""
decomp(uudata)
''' %(outs)

outpy = open("decomp.py","w+b")
outpy.write(decomppy)
outpy.write(taildata)
outpy.close()
subprocess.Popen("chmod +x decomp.py",shell=True)
