I have to do that for several hundreds of files...I am almost there it is kind of working for one file but once i put a loop in the story, then everything crashes... could anybody here offer some help ??? regards Yoann -- http://mail.python.org/mailman/listinfo/python-list
Python gp.ListFeatureClasses return only one file
Hi All,
I m using the gp.ListFeatureClasses to make a list of file in my
directory (containing several hundreds of file)
however when I print the variable in which the List is supposed to be
stored, the print just return one file name
does any one have an idea
# Import system modules
import sys, string, os, arcgisscripting, glob, arcpy
# Create the Geoprocessor object
gp = arcgisscripting.create()
# define the workspace
gp.Workspace = r"F:\front\shp_Files\calving_front"
# list the file in the workspace
try:
shpList = gp.ListFeatureClasses("*.shp")
shp = shpList.Next()
print shp
except:
print arcpy.GetMessages() # allows to get error message when they
happen

debugger on system with Python 2 and 3
Hi, I am a relative newcomer to the Python language, and only write Python 3. Now I would very much like to a more-than-basic debugger. However it seems as if the fact that I have both Python 2 and 3 on the system complicates the matter... First I tried to use something called pydb, but it seems to invoke python 2, and I don't know quite how to (or whether I can) configure it for Python 3. Secondly I installed something called IDLE3, which complains that TK is not configured for Python 3. I don't want to remove or default to Python 2, as there seem to be a number of programs that rely on it. I wonder how best to avoid my problems. Would perhaps somebody in the same sort of situation share their wisdom?? Yo -- http://mail.python.org/mailman/listinfo/python-list
Re: debugger on system with Python 2 and 3
Thanx Alan, I am using Fedora Core 11. I wanted to use emacs, rather than the full-blown IDE or entirely gui-based debugger, and that's why I was drawn to pydb in the first instance. If there's no other choice I don't mind using winpdb, but it is installed (through Yum) under Python2 library and invokes Py2 at default... Don't quite know how to adapt it to Py3 or install the right version under the right directory, yet. It seems as if some environmental variable change is necessary. On the whole it doesn't seem that there's much support in the third-party debuggers in general as yet... In the meantime I might ask if it is possible to adapt pydb (or perhaps, IDLE) for Py3. Might be just a change in a env variable or two...
