Problem with optparser or In

[Florian Lindner]

Hi,
I'm not sure where the problems lies...
I'm using optparse and I've a option defined:

parser.add_option("-t", "--type", action="callback",
callback=option_callback, type="string")

def option_callback(option, opt, value, parser, *args, **kwargs):
if (str(option) == "-t/--type") and (opt in ("mailbox", "ftp")):
print "Error!"
else:
parser.values.type = opt

This should print error if the commandline is "--type=ftp" or
"--type=mailbox" (same for the short args).
But it never gets till Error... Although opt contains "mailbox" or "ftp".
What's wrong there?


Thanks,
Florian

Change to
if (str(option) == "-t/--type") and (value in ("mailbox", "ftp")):

if (str(option) == "-t/--type") and (opt in ("mailbox", "ftp")):
print "Error!"
else:

In such cases the poor man's debugger aka print statement is your friend.

print opt

would reveal that opt contains the actual option and value - surprise,
surprise -the value.
