Open a text file beginning with agr* in python to incorporate in model builder

MeredithGreen — Wed, 30 Jul 2014 17:34:02 GMT

I have an iterator that is going through a folder and iterating through every folder inside of it that begins with a*. Next I need a script or tool that opens text files located inside the a* folder that begin with agr*. Then I need to take that agr* text file and plug it into a Table to Table tool. Does anyone have any idea of the best way to approach this?

Yes this is very feasible with python. Using arcpy.da.Walk, we can go through all subdirectories of a selected work space and get all the text files that are within them. Then we check if they start with "agr" and if we do, add the file path and file name to an empty list, which can iterate over for the table to table tool.

Some sample code to get you going.

import arcpy
import os
#Set your own workspace below
workspace = "c:/data" #Example
text_files = []
for dirpath, dirnames, filenames in arcpy.da.Walk(workspace, datatype="Text"):
  for dirname in dirnames:
    for filename in filenames:
      if (dirname[0] == "a") and (filename[0:2] == "agr"):
        text_files.append(os.path.join(dirpath, filename))
 
outLoc = "C:/data/Output" #Example
 
for textfile in text_files:
  outName = textfile.split("\\")[-1]
  arcpy.TableToTable_conversion(textfile, outLoc, outName) #Fill in optional parameters as needed
