printing number of files per directory python

Question

I found several questions on this topic but none that addressed the problem I am seeing. I apologize in advance I'm new to python. What I am trying to do is count the number of files in every directory beneath somedir/ so I would get something like:

dir-a: 13
dir-b: 6
dir-c: 21

I thought the easiest way to prove I could do this would be:

from os import listdir
from os.path import isfile, isdir

def walk(p):
  for file in listdir(p):
    if isfile(file):
      print("File: " + file)
    elif isdir(file):
      print("Dir: " + file)
      walk(file)
    else:
      print("Unknown: " + file)

path = raw_input('Enter path to search')
walk(path)

But the first iteration is the only one that works as expected. I have tried adding the full path of the file with os.path.abspath and a couple other ways to ensure the file is the same in the first iteration as it is in recursive calls. I have checked the type with type(file) and it is 'str' and even if the path+filename is correct and exists the above program stills fails to produce the expected results. For example on a directory structure like:

dir-a/
     file-a.1
     file-a.2
     dir-b/
          file-b.1
          file-b.2
     file-a.3

I would expect:

File: file-a.1
File: file-a.2
Dir: dir-b
File: file-b.1
File: file-b.2
File: file-a.3

but I get:

File: file-a.1
File: file-a.2
Dir: dir-b
Unknown: file-b.1
Unknown: file-b.2
File: file-a.3

So basically all files are not getting identified as files or dirs on recursive calls. I looked through the docs on listdir, isfile, and isdir and it still doesn't make sense. I've tried with python 2.7.5 and 3.4.0, same behaviour. Any help is appreciated.

Answer 1

You are correct about the absolute path thing. You can build the path yourself though by simply joining the contents of listdir on the variable passed to walk

from os import listdir
from os.path import isfile, isdir, join

def walk(p):
  for item in listdir(p):
    item = join(p, item)
    if isfile(item):
      print("File: " + item)
    elif isdir(item):
      print("Dir: " + item)
      walk(item)
    else:
      print("Unknown: " + item)

path = raw_input('Enter path to search')
walk(path)

Output (Note: errors out eventually cause I don't have root on this box so when it gets to /root it crashes, but that's easily catchable)

Enter path to search/
