The xml data is generated on Windows (python 2.6.2) and sent using a post
request to a Django server. The django server is running on Ubuntu server with
python 2.6.2. The post data is passed to minidom for parsing.

This topic came up before. =] See below. Not sure how 'standardised' this
is, though.
Double precision:
>>> import struct
>>> struct.unpack('d', struct.pack('Q', 1))[0]
4.9406564584124654e-324
Float precision:
>>> struct.unpack('f', struct.pack('L', 1))[0]
1.4012984643248171e-45

You could find it for yourself:

I'm building an RPC service, and I need to validate the input and
provide informative error messages to users. What would be the best
way to do this? Simple `if` statements each raising a custom

Is there some standardized way (e.g. some "official" module of such
limit constants) to get the smallest positive float that Python
will regard as distinct from 0.0?

Why will multiple interpreters give you better concurrency? You can
have more than one thread in the same interpreter.

Strictly speaking, the GIL is global to the Python DLL, not the

Hi Maggie,
I see you have already gotten a lot of useful help.
One additional suggestion would be to use a different
variable name other than 'sum' as sum is a Python

Actually, I modified my program to have a single shared Py-interpreter
across all threads to test the usage of GIL. So, I did Py_Initialize
in main() function and only called that python function in different
threads.
But this is not the way I want to use interpreters in my code.

In the beginning, strings, tuples, and numbers were immutable, and
everything else was mutable. That was simple enough. But over time,
Python has acquired more immutable types - immutable sets and immutable
