grp.struct_group bug ?

[spam]

Is this a bug ?

Running the following script with Python 2.3.5:
.................
#!/usr/bin/python

import grp

# groups = grp.getgrall()

agroup = grp.getgrnam('wheel')
print agroup
print type(agroup)

print agroup.__contains__('john')
print agroup.__contains__('x')
.................
This is the output I get:
.................
('wheel', 'x', 199, ['marcel', 'john', 'ben'])
<type 'grp.struct_group'>
False
True
.................
I expected __contains__ to tell me if a given user is part of a group, but
it seems that it's checking the password field ??

Thanks.

Yves.

The tuple returned by getgrnam contains four fields:
the group id (gr_gid), a list of group members (gr_grmem),
the group name (gr_name), and the group password (gr_passwd).

If you want to see if user 'john' is in the list of group members,
use:

if 'john' in agroup.gr_mem:
print "Found john in group wheel"

If you want to see if a password was set:

if agroup.gr_passwd == "":
print "No group password was set for group wheel"

and so on.

Hope this helps,
