That parses the date and discards the result.

'date' is a string, it doesn't have a 'strptime' method.
When you parsed the date you got a datetime object; _that_ has the
'strptime' method.
Correction: the datetime object has the 'strftime' for formatting the
date.
I don't need to store the date i just want to make sure is entered correctly.
I would like to have the user type the date like
21 02 2013
and then convert it to 2013-02-21 because thats how mysql wants the date in
order to store it.
Please show me how to write this.
The 'strptime' method parses the string and returns a datetime object,
and you can then use that object's 'strftime' method to format it to
the desired string.
Also, can you show me how to write it that if so even if the user entered date
is wrong it doesn't just crash the cgi-script?i know i can use tr: expect: but
i want to avoid it, somehow i need to check the date in the same if statemnt
like i do with the other user defined varibles for validity.
It _doesn't_ crash the cgi-script.
You're telling it to exit if an exception is raised.
If you don't want the cgi-script to exit, don't call 'exit'.
if( task and ( price and price.isdigit() and price.__len__() <= 3 ) and ( date
and datetime.strptime(date, '%Y-%m-%d') ) ):
Thanks.
