Creating folders help (python beginner)

chukwuemekaobilor — Thu, 23 Feb 2012 15:18:26 GMT

I am trying to create folders and each folder will have a name from a field in my grid layer.
My grid has 500 tiles and I need to create 500 folders. The naming convention is like 001A1, 001A2,
001A3, 001B1, 001B2, 001B3, 001C1, 001C2, 001C3, 002A1...................

My code starts like this
import sys, string, os, arcgisscripting, traceback
gp = arcgisscripting.create()
env.workspace = "C:\Backup Files\Backup Files\GISPROJECTS\Python_Practice"

# Set local variables
output_folder_path= "C:\Backup Files\Backup Files\GISPROJECTS\Python_Practice"out_name = "folder1"
output_folder_name = foldername

# Execute CreateFolder

Use a Search Cursor to loop through the grid cells (I assume your grid is a grid of polygons...?) to get the cell's value. Then, inside the loop, incorporate the cell value into a path string, then use that string inside os.mkdir().

this line will fail
env.workspace = "C:\Backup Files\Backup Files\GISPROJECTS\Python_Practice"
either use double backslashes, a single foreslash or append an r to the beginning of the path
