python 3.x - Set position according part of an objectname -

i'm trying script in blender3d using python. i've got bunch of objects in scene , want translate them using numerical part of objectname.

first of collect objects scene matching part of name.

root_obj = [obj obj in scene.objects if fnmatch.fnmatchcase(obj.name, "*_root")] 

this gives me list with:[bpy.data.objects['01_root'],bpy.data.objects['02_root'],bpy.data.objects['03_root'],bpy.data.objects['00_root']]

my goal move these objects 15x corresponding part of name. '00_root' doesnt have move, '01_root' has move 15 blender units , '02_root' 30 blender units.

how exctract numberpart of names , use them translation values.

i'm pretty newb python appreciate can get.

a string list of characters, each character can accessed index starting 0, first character name[0], second name[1]. list can use slicing portion of list. if value first 2 characters can value name[:2] can them turn integer int() or float float(). combined becomes,

val = int(name[:2]) 

you have number can calculate new location with.

obj.location.x = val * 15 

if number of digits in name might vary can use split() break string on specific separating character. returns list of items between specified character, if want first item turn integer.

name = '02_item' val = int(name.split('_')[0]) 

using split allows multiple values in name.

name = '2_12_item' val1 = int(name.split('_')[0]) val2 = int(name.split('_')[1])
