>>> def check():
print 'Called Once'
return 2

Happy Hacking.

Looks like a 32/64 bit related mixup.
See:http://stubblog.wordpress.com/2009/06/07/installing-psycopg2-on-osx/
Report back if you had any success.

Assuming you're talk
Hi All,
I am trying to use the psycopg2 library to connect to Postgres database.
However, on importing psycopg2, I get the following error.
Traceback (most recent call last):

Did u mean to say that evaluating b only once applies to a

more compact
is_in_range = startdate < date < enddate
that is what I was doing - too verbose, wanted to know if I could use 'in'.

It is nice and easy thankfully.
datetime.date and datetime.datetime both support < > operators
So:
if startdate < date and date < enddate:
print "date in range"
