[GIS] Renaming shapefiles using loop in Python

arcpyshapefile

I'm trying to clean up a list of shapefiles that I've created using GME. I have a series of shapefiles (polylines and polygons) that are named "ID_final_kde.img_LSCV.shp" and "ID_final_kde.img_LSCV_poly.shp", where ID is unique to each individual. I'm trying to rename the polylines to "ID_final_LSCV.shp" and the polygons to "ID_final_LSCV_poly.shp", to no avail.

Here's what I've been trying:

# import modules
import arcpy, os, arcinfo, xlwt,time, glob
from arcpy.sa import *

arcpy.CheckOutExtension('spatial')

path = os.getcwd()
arcpy.env.workspace = path + '\\fawn_locations\\FINAL'
arcpy.env.overwriteOutput = True

lines=arcpy.ListFeatureClasses(feature_type='Polyline')
for each in lines:
    arcpy.Rename_management(each, each[:-16] + 'LSCV')

poly=arcpy.ListFeatureClasses(feature_type='Polygon')
for each in poly:
    arcpy.Rename_management(each, each[:-20] + 'LSCV_poly')

This code renames the .shp file, but not the associated .cfg, .prj, or .shx files, so I can no longer open the shapefile in ArcMap. How can I loop through the folder, renaming all the files while preserving their extensions?

I'm just learning python.

I don't believe you even need arcpy for this necessarily. I think you just need to change the name of all the shapefiles with that name. So to rename from 'abc' to 'def' you would have abc.shp, abc.cfg, abc.prj, etc. become def.shp, def.cfg, def.prj, etc.

import sys
import os

def renameFiles(path):
    for root, dirs, files in os.walk(path):
        for file in files:
            filename, extension = os.path.splitext(file)
            os.rename(os.path.join(path, file), os.path.join(path, filename[:-20] + 'LSCV_poly' + extension))

renameFiles(pathToRename)

[GIS] Checking for number of shapefiles in directory using Python

Check the glob library:

import os
import glob
path = "c:\\my\\dir"

flist = glob.glob(os.path.join(path,"shapefile*"))  <- Notice the *

>>> flist 
["c:\\my\\dir\shapefile.prj","c:\\my\\dir\shapefile.shp",...]

If you want just the fname without the path attached:

 os.path.basename(flist[0]) 
 >>> shapefile.prj

if you want just the file name without the extension:

os.path.basename(flist[0]).split(".")[0]
>>> shapefile

Also if the list is empty, then the file doesn't exist:

if flist not:
    print "File not found"
    break #or os.exit(1)

Edit: Also to check for the only filename in path :

import os
import glob
path = "c:\\my\\dir"

flist = glob.glob(os.path.join(path,"shapefile*"))  <- Notice the *
mlist = []
for file in flist:
    if os.path.basename(file).split(".")[0] not in mlist:
        mlist.append(os.path.basename(file).split(".")[0])
if len(mlist)>1: #(More than filename)
    break

To check if only one shapefile in the dir:

 def file_check(path):
      """Returns true if in path there is only one basename"""
      import os
      mlist = [] 
      for file in os.listdir(path):
          if os.path.basename(file).split(".")[0] not in mlist:
                mlist.append(os.path.basename(file).split(".")[0]
   if len(mlist)>1:
            return True
    else:
            return False

QGIS – Renaming Shapefiles in QGIS Using PyQGIS

QGIS 3.22

In QGIS 3.22 you have an option to rename layers using the context menu in QGIS Browser:

QGIS 2.x

For doing so, you would need to i) remove the layer from the ToC, ii) rename the files that conform the Shapefile (i.e., shp, dbf, shx, prj, and the like), and iii) load the renamed layer to QGIS. But we do need to automatize such workflow!

If you look at the steps, they're similar to what the Table Manager plugin does. So, I adapted such plugin's code to rename Shapefiles, you can find it here.

You can use it in this way (first try with a small backup project to see how it works):

Rename your QGIS layers in the ToC, these new names will be taken to overwrite your corresponding Shapefiles names.
Save your QGIS project in the same folder as the script rename_shapefiles.py
Open the QGIS Python console.

Copy the next code snippet there:

 from rename_shapes import RenameShapefiles
 for lyr in iface.mapCanvas().layers():
     rn = RenameShapefiles( iface, lyr )
     rn.doSave()

That's it! I've tested it on GNU/Linux, QGIS 2.6. The order of layers in the ToC varies after running the code.

Let me know if you have any issue.

If you need the layer order to be preserved, ask a new question, perhaps I can look at it :).
