django shell < file.py import functionality

Question

I'm trying this through a sentry command:

sentry --config=sentry.conf.py shell < add_user.py

add_user.py looks like this:

from django.contrib.auth.models import User

try:
    import authfile
except Exception as e:
    print "authfile not present, %s" % e

def conv_dict(the_dict):
    sen_username = the_dict['sen_username']
    sen_email = the_dict['sen_email']
    sen_password = the_dict['sen_password']
    print sen_username
    return sen_username, sen_email, sen_password

for t, imp_dict in authfile.__dict__.iteritems():
    if isinstance(imp_dict, dict) and not t.startswith('_'):
        sen_username, sen_email, sen_password = conv_dict(imp_dict)
        try:
            new_user = User.objects.create_user( sen_username, sen_email, sen_password)
            new_user.is_superuser = True
            print "created new user: %s" % imp_dict['sen_username']
        except Exception as e:
            print "could not create new user: %s" % e
            pass

authfile is a set of dictionaries that populate the values called for in the for loop.

If I run the interactive shell and import this file, it works. If I try to pull it in with <, it runs without any output and exits, but it does not create the users like I does if I run it in the shell interactively. The output looks like this:

sentry --config=../sentry.conf.py shell < add_super.py
