I think you intend on using simply the command-line infozip tool from
python system commands:
mycmd = "zip -r content.xml foo.zip"
mycmd = "zip -i your.blob foo.zip"
try:
mycmd = "zip -r content.xml foo.zip"
retcode = call(mycmd, shell=True)
mycmd = "zip -i your.blob foo.zip"
retcode = call(mycmd, shell=True)
if retcode < 0:
print >>sys.stderr, "Child was terminated by signal", -retcode
else:
print >>sys.stderr, "Child returned", retcode
except OSError, e:
print >>sys.stderr, "Execution failed:", e
