Search and Sort Shapefiles

[Low_Ki_]

Hello 
How can I search my shapefiles using python codes to find all shapefiles that start with for instance "landuse" and show the results in a message box? 
I used the following code but they return nothing. 
Would you have a look on them and remind me about errors?
Thanks for help.

my code here

# import arcpy module

import arcpy
import sys
from arcpy import env
import os
import fnmatch
#the list of variables all hard coded to decrease errors 
# Set the workspace for  ListFeatureClass functions
env.workspace = "C:/GIS_database/module5/module5data.mdb"
# set the variables
# path to the shapefiles
folder = "C:/GIS_database/module5/module5data.mdb"
# Looking for all files starting with landuse and a wildcard *
pattern = 'landuse*.shp'
# This is a master shapefile
filename = "C:/GIS_database/module5/land_use_merged.shp"
# This is the list of shapefiles starting landuse
shpList = []
# add file names to shpList.
for path,dirs,files in os.walk(folder):
   for filename in fnmatch.filter(files, pattern):
        shpList.append(os.path.join(path, filename))
# Add all names stored in shpList to a message box
for fc in shpList:
   arcpy.AddMessage(fc)

You need to use ctrl + shift + v to paste code between python code blocks
