[Tutor] Testing a variable for being a number, string or other object...

[Marc Barry]

Dear All:

My first question is how do I test if a variable is a number or a string?  I 
need to to do this for error checking on values passed into methods.

The second question I have is does Python have a way of testing for 
instances like Java does?  For example, the "instanceof" operator that lets 
you determine if an instance is of a certain type?

Regards,

Marc
