Print number of files in python directory

I found several questions on this topic, but none of them addressed the problem that I see. I apologize in advance, I'm new to python. What I'm trying to do is count the number of files in each directory under somedir / to get something like:

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

I thought the easiest way to prove that I could do this:

 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 tried adding the full path to the file using os.path.abspath and a couple of other ways to ensure that the file is the same in the first iteration as in the recursive calls. I checked the type with type(file) and it is 'str' , and even if the path + file name is correct and exists, the above program frames do not give the expected results. For example, in a directory structure, for example:

 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

Thus, basically all files are not recognized as files or channels in recursive calls. I looked through the documents on listdir , isfile and isdir , and that still doesn't make sense. I tried with python 2.7.5 and 3.4.0, the same behavior. Any help is appreciated.

You are right about the subject of the absolute path. You can build the path yourself by simply linking the contents of listdir to 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)

Exit (Note: errors ultimately lead to the fact that I do not have a root in this field, so when it comes to /root it crashes, but it will catch easily)

You can execute shell commands in Python - http://www.cyberciti.biz/faq/python-run-external-command-and-get-output/

The following command in Shell will display the number of files in the directory:

 ls -1 targetdir | wc -l
0

An alternative way using walking from the standard library:

 import os from collections import defaultdict file_counter = defaultdict(list) for root, dirs, files in os.walk("/tmp"): file_counter[root] += files for k,v in file_counter.items(): print(k, len(v))

Print

 /tmp/.felix/osgi-cache580844e_14a135fd513_-8000/bundle14 5 /tmp/.felix/osgi-cache71530794_14a2d25c3b4_-8000/bundle3/version0.0 1 /tmp/.felix/osgi-cache580844e_14a135fd513_-8000/bundle13 5 /tmp/.felix/osgi-cache580844e_14a135fd513_-8000/bundle1/version0.0 1 /tmp/.felix/osgi-cache71530794_14a2d25c3b4_-8000/bundle18 5 ...

But the disadvantage is that it saves a dict of all file names and directions. It can be expensive, you are planning on traversing large file systems.
