Thanks for the link (although Java was only one of the languages I was
thinking of).
Anyway, I got another "problem" (read: being used to do it like this in other
languages). I'm used to use statically typed languages and for me one of the
advantages is that I can be sure that a parameter is of a certain type. So in
Java I could write
void doSomething( data : SomeClass ){ ... }
and I would be sure at compile time that I would only get SomeClass objects
as parameters into the method.
In learning Python I've understood that I should write code in such a way
that it can handle different data and this is fine with me. But what if I
have a class where different attributes should only have values of a certain
type and everything else is an error.
For example, if I have an class that defines three attributes: first and last
name plus email address. The only valid data types for the first two are
strings and for the last an EmailAddress class.
How should I handle this in Python?
Should I use just don't care (but I'm going to send the data to a database so
I need to ensure that the data is OK)? Should I use 'isinstance' and check
manually? Or should I do something else?
(I've been trying to figure out this and other things but I haven't found
much in books or web sites)
