Python, like most programming languages, uses the period as the decimal separator regardless of what your local language uses. Try this: def reclass(ALTITUDE):     if ALTITUDE == 39.99:         return 40     else:         return ALTITUDE ... View more

I'm more that a little curious about the motivations for needing to know this and dubious that it matters, but I'll indulge you:   1. There are some entries in the sys.path in both setups that I honestly don't see where they came from. The first one in the lists above came from my PYTHONPATH, and the the last three are in the .pth file in site-packages. Where did all the others entries come from? From the bootstrapping process Python does when it first initializes itself in the process. There are other places Python looks (%PATH%, %PYTHONPATH%, registry keys, site.py and sitecustomize.py). Additional bin directories are injected in the path in the CPython code based on the current path.   2. There are some imports (sys, arcpy) that the ArcMap python window has loaded already. Where did that happen? When the Geoprocessing framework bootstraps itself to run Python scripts. It imports some commonly-used modules for script tools/Field Calculator that users tend to forget to import just as a courtesy.   3. The ArcMap python prompt is picking up some paths from somewhere mysterious (in italic above) The same items would be found in python.exe if it didn't know to short-circuit that process. Since the working directory of python.exe is c:\python27\arcgis10.1, it knows to ignore the bin dircetories of other Python 2.7 installs it finds. When it's running embedded in another program such as arcmap.exe, it isn't necessarily as sure as to which install is canonical so it errs on the side of inclusiveness. Again, look in the registry and environments in addition to where you've looked already   4. In all setups, what's up with the path: C:\WINDOWS\system32\python27.zip. That file does not exist in my install. Legacy reasons. It's part of Python itself. I'm sure it's deprecated by now, I think as the current bootstrap process was being refined it was a part of it. Basically you can place a python27.zip in that location and fill it with .py files and they will show up as importable modules. For instance, you can place a site.py or sitecustomize.py in there that sets the sys.path and you'd get a uniform sys.path across the board in all places.   (cp - reformatted) ... View more

.value will be a semicolon delimited string. If you use the .values attribute (note the plural), it will be a list instead, which is likely what you want. We couldn't make .value return a list for backwards compatibility reasons. ... View more
