How do you walk through the directories using python?

Question

I have a folder called notes, naturally they will be categorized into folders, and within those folders there will also be sub-folders for sub categories. Now my problem is

Answer 1

I've come across this question multiple times, and none of the answers satisfy me - so created a script for that. Pytohn is very cumbersome to use when it comes to walking through directories.

Here's how it can be used:

import file_walker


for f in file_walker.walk("/a/path"):
     print(f.name, f.full_path) # Name is without extension
     if f.isDirectory: # Check if object is directory
         for sub_f in f.walk(): # Easily walk on new levels
             if sub_f.isFile: # Check if object is file (= !isDirectory)
                 print(sub_f.extension) # Print file extension
                 with sub_f.open("r") as open_f: # Easily open file
                     print(open_f.read())

Answer 2

Based on your short descriptions, something like this should work:

list_of_files = {}
for (dirpath, dirnames, filenames) in os.walk(path):
    for filename in filenames:
        if filename.endswith('.html'): 
            list_of_files[filename] = os.sep.join([dirpath, filename])

Answer 3

an alternative is to use generator, building on @ig0774's code

import os
def walk_through_files(path, file_extension='.html'):
   for (dirpath, dirnames, filenames) in os.walk(path):
      for filename in filenames:
         if filename.endswith(file_extension): 
            yield os.path.join(dirpath, filename)

and then

for fname in walk_through_files():
    print(fname)

Answer 4

You could do this:

list_of_files = dict([ (file, os.sep.join((dir, file)))
                       for (dir,dirs,files) in os.walk(path)
                       for file in files
                       if file[-5:] == '.html' ])
