Answer 1

You could also use

import os    

files_in_dir = os.listdir(path_to_dir)
for file_in_dir in files_in_dir:
    #do the check you need on each file

Answer 2

This does directory and all subdirectories:

import os, os.path

for root, _, files in os.walk(dirtocheck):
    for f in files:
        fullpath = os.path.join(root, f)
        if os.path.getsize(fullpath) < 200 * 1024:
            os.remove(fullpath)

Or:

import os, os.path

fileiter = (os.path.join(root, f)
    for root, _, files in os.walk(dirtocheck)
    for f in files)
smallfileiter = (f for f in fileiter if os.path.getsize(f) < 200 * 1024)
for small in smallfileiter:
    os.remove(small)

Answer 3

you can also use find

find /path -type f -size -200k -delete

Answer 4

Generally ls -la is in bytes.

If you want it in "human readable" form, use the command ls -alh.
