[Tutor] clarification on os.path.walk

[Chandrashekar]

Hi,

I have a program like this.

import os,os.path
import re

def print_files(arg,dir,files):
    '''print 'arg', arg
    print 'dir', dir
    print 'files',files'''
    for file in files:
        path = os.path.join(dir,file)
        path = os.path.normcase(path)
        if re.search(r".*\.txt",path):
            print path
 

os.path.walk('.',print_files,1)

My doubt is that what does the argument stand for in this program?
os.path.walk('.',print_files,0)
os.path.walk('.',print_files,1)
os.path.walk('.',print_files,2)

all seems to be rendering the same output. Can anyone clarify when this argument is used.

Thanks,
Chandru
