Python script for finding large files in given directory

The task is to find (and print names of) large files in given directory (including one level under it).

#!/usr/bin/env python
# -*- coding: utf-8 -*-

find large (1 gb) files in given directory [C:\Projects] (root)
(including one level under root dir)

import os

def get_file_paths(directory):
  This function will generate the file names in a directory
  tree by walking the tree either top-down or bottom-up. For each
  directory in the tree rooted at directory top (including top itself),
  it yields a 3-tuple (dir-path, dir-names, file-names)

  file_paths = [] # list to store all of the full file-paths

  # walk the tree
  for root, directories, files in os.walk(directory):
   for filename in files:
    # join the two strings in order to form the full file_path
    file_path = os.path.join(root, filename)
    file_paths.append(file_path) # add it to the list

  return file_paths

def dir_find_large_size(directory, max_size):
  This function looks for files with size bigger than max_size
  (in mega bites) and prints file path if such file is found
  # exec get_file_paths() function and store its results in a variable

  full_file_paths = get_file_paths(directory)
  size_mb = 0

  for file_path in full_file_paths:

   # test file_path
   if os.path.isfile(file_path):
    size_mb = ((os.path.getsize(file_path)) / 1024) / 1024
    if size_mb > max_size:
     print (file_path)
     print ('size: {0} mb'.format(size_mb))
    print ('Can not read file:')
    print (file_path)
