It's been awhile since I've used python, and I recall there is a way to
find the version number from the IDLE command line prompt. dir, help,
__version.__?

I made the most minimal change to a program, and it works for me, but
not my partner. He gets

Traceback (most recent call last):
File "C:\Documents and
Settings\HP_Administrator.DavesDesktop\Desktop\NC-FireballReport20100729.py",
line 40, in <module>
from scipy import stats as stats # scoreatpercentile
File "C:\Python25\lib\site-packages\scipy\stats\__init__.py", line 7,

import scipy.special as special

22, in <module>
from numpy.testing import NumpyTest
ImportError: cannot import name NumpyTest

Here are the first few lines of code.

import sys, os, glob
import string
from numpy import *
from datetime import datetime, timedelta
import time
from scipy import stats as stats # scoreatpercentile

I'm pretty sure he has the same version of Python, 2.5, but perhaps not
the numpy or scipy modules. I need to find out his version numbers.

Try:

import numpy
help(numpy.version)

BTW, on Python 2.6 I can see that there's "numpytest" but not
"NumpyTest".

It is now written in my Py book. Thanks.

I have to stick with 2.5 for comparability with my partner. He's
non-Python but was able to get Python 2.5 working. I think he somehow
bumped ahead to a later version of numpy than I have.

Hi Wayne,
FYI it's got nothing to do with IDLE, it's just a question of whether
or not the module in question exposes any kind of a version attribute.
There's no standard, unfortunately. The most popular convention seems
to be via an attribute called __version__, but I've also seen
__VERSION__, VERSION, and version.

Here's some code that I wrote that you might find useful. It's from a
setup.py and it checks a list of modules on which our project depends
to see if (a) they're installed and (b) if the version installed is
adequate. In the snippet below, dependencies is a list of custom
classes that represent modules we need (e.g. numpy).


# Try each module
for dependency in dependencies:
try:
__import__(dependency.name)
except ImportError:
# Uh oh!
dependency.installed = None
else:
# The module loaded OK. Get a handle to it and try to
extract
# version info.
# Many Python modules follow the convention of providing
their
# version as a string in a __version__ attribute.
module = sys.modules[dependency.name]

# This is what I default to.
dependency.installed = "[version unknown]"

for attribute_name in ("__version__", "__VERSION__",
"VERSION",
"version"):
if hasattr(module, attribute_name):
dependency.installed = getattr(module,
attribute_name)
break

Hope this helps a little,
Philip
