Functional programming in Python

Although users usually think of Python as a procedural and object-oriented
language, it actually contains everything you need for a completely
functional approach to programming. This article by David Mertz discusses
general concepts of functional programming, and illustrates ways of
implementing functional techniques in Python.

Getting version 2.0

Python programmers have recently acquired a shiny new toy with the release
of version 2.0. Python 2.0 builds on the strengths of previous Python
versions, while adding a number of new conveniences and capabilities. This
previous article from David Mertz contains his impressions of Python's
newest version, and some tips on using it effectively.

Subject: [JPython] Exception handling doubt

Hi , 

  I am a newbie trying to get familiar with JPython. It was pretty
interesting but I could not find any info regarding the handling of
compulsory exceptions of java in JPython. Any help is greatly appreciated.

Thanks in advance.
Suresh

I wasn't sure what you meant by "compulsory".
"What is thrown must be declared thrown or caught" is Java talking,
not Jython (JPython).  "compulsory" does not apply to Jython.

Adding an exception handler for a Java exception is similar to how
you would catch an exception in Java.  Jython's exceptions are classes, so
are Java's.  To handle an exception is to handle an instance of that
exception class.  So:

> >>try:

...    raise SyntaxError
...except SyntaxError:
...    pass # handle instance of SyntaxError here

SyntaxError is just an instance (PyInstance) of the SyntaxError class.
What's a Java exception you ask?  It's an instance (PyInstance
of a PyJavaClass) no different than the SyntaxError above to Jython users
like me.  So:

> >> import java

> >> import sys

> >>

> >> try:

...     raise java.lang.NullPointerException
... except java.lang.NullPointerException:
...     c, i, tb = sys.exc_info()  # fetch class, instance, tb
...     print i, "is a", type(i)   # see, nothin' special
...
java.lang.NullPointerException is an org.python.core.PyInstance

The short of it is add "except javaclass" for any java exception you
need to catch.  An "except" without any class specified is generic
and catches everything.

(Warning: I'm only really talking about Jython, the successor to JPython.
If this question was something unique to JPython, ignore this.  Also
note that upgrading to Jython is recommended, and I even think
these JPython lists are somewhat abandonded in favor of the Jython lists
found at jython.sourceforege.net- I've just been to lazy to
unsubscribe).

Cheers,
Robert

Thanks for the clarification. I did not set the path for the jar file
initially
so I was getting an error. 

regards,
Suresh
