openstreetmap - How to convert a set of osm files to shape files using ogr2ogr in python -

i believe question asked can't find answer placing before you. having problem while running script convert osm files shp files. script reading osm files creating 1 shp file of first osm file @ end instead of converting osm files. providing code used below. please kindly me in resolving me this.

the way used os.walk returns in archivos osm files in last ruta of tree structure traversed. possibly (at least part of) problem, or may in future.

you have use os.walk differently:

import os, re  ext_regx = '\.osm$' archivos = []  ruta, dirs, archs in os.walk( path ) :     arch in archs :         if re.search( ext_regx, arch ) :             archivos.append( os.path.join( ruta, arch ) )  osmfile in archivos :     print( osmfile )     ... 

now if code inside for loop not mean to, issue. suggest you:

1. add print( systemoutput ) check each command executed intend be.
2. check files , dirs refered in command correct.

ps: each item in archivos contain dir part, have split folder part, instead of joining.

ps2: might need use double backslashes dirs. also, bear in mind os.sep.
