Thanks for everyone’s help, much appreciated, I’ll check
out the isinstance function. Jon -----Original Message----- Jonathan Bowlas wrote: > Hi Listers, > > I have a requirement to test for a data type could someone tell me

correctly but > if it is passed as a string nothing happens. You need the isinstance() function. For example you can use isinstance(selecteddeptcodes, list) to test if your variable is a list.
If you want to test the other way round use isinstance(selecteddeptcodes, str) if your variable is a string, isinstance(selecteddeptcodes, unicode) if it's a unicode string or isinstance(selecteddeptcodes, basestring) to test if it's a string or unicode string. Read more about this function and the types to test for
in http://docs.python.org/lib/built-in-funcs.html. If you already have the code for a list argument I'd check if it's not
a list and then turn it into a list: if not isintance(selecteddeptcodes, list): selecteddeptcodes = [selecteddeptcodes] Bye, Dennis -- http://mail.python.org/mailman/listinfo/python-list |
