Getting data with python

DorienJanssen — Mon, 07 Apr 2014 08:28:35 GMT

I'm trying to write a python program, in which python searches for files on an external harddrive. I can get python to tell me whether the files exist, but not to retrieve them. I'm rookie with python so I hope somebody can help me.

The files the program has to retrieve are raster datasets and are used in a model builder program then. The complete modelbuilder program works, the python part does not.

I hope somebody will be able to help me

#specify the workspace rasters are located in
ws = "H:\Documents\ArcGIS\Default.gdb"
arcpy.env.workspace = ws

#for each Raster in the workspace, do something
rasters = arcpy.ListRasters()
for r in rasters:
  desc = arcpy.Describe(r)
  rastername = desc.Name
  print "Raster Name: %s" % (rastername)

Are you hoping to copy the data from your removable drive to your local HDD? if so, then you should use the shutil module

import shutil
sourcefile = r'E:\path\to\file\example.ext'
destinationfile = r'C:\path\to\where\File\gets\copied\copy_example.ext'
shutil.copy(sourcefile, destinationfile)
