how read number of files in specific folder using python? example code awesome!

to count files , directories non-recursively can use os.listdir , take length.

to count files , directories recursively can use os.walk iterate on files , subdirectories in directory.

if want count files not directories can use os.listdir , os.path.file check if each entry file:

import os.path path = '.' num_files = len([f f in os.listdir(path)                 if os.path.isfile(os.path.join(path, f))])

or alternatively using generator:

num_files = sum(os.path.isfile(os.path.join(path, f)) f in os.listdir(path))

or can use os.walk follows:

len(os.walk(path).next()[2])

i found of these ideas this thread.

i having super hard time compiling , using taglib 1.6.3 in qt project. i've tried can think of. taglib claims supported through cmake i'm not having luck. furthermore, i'm confused kinds of files need qt libs! i've built *.a files, *.lib, , *.dll. understand far... believe since i'm working in windows *.lib want. no matter do, end "undefined references" taglib functions try use when try compile qt project. have tried mingw32, msys, visual studio 2008, , cross-compiling windows on linux. turning nothing. what makes less sense me if compile same taglib source qt on mac (g++ think?) works fine! somewhere in windows compilation procedures have going wrong. have been smacking face on desk 30 (on , off) hours trying figure out. since qt uses mingw must compile taglib same compiler? if compile *.lib's visual studio not compatible? are *.a libraries usable in windows? (assuming mingw) i'm still trying handle on c++ stuff, after reading coun...

my goal simple today, trying work out proper way implement compareto (or comparable) interface class extends defaultmutabletreenode. the problem this : have class represents times. i've written compareto method (which works desire) i've tested out arrays.sort() marvelous results. now lets have jtree bunches of different objects, this: new specialnode("zomg string!"); // add group of nodes right here new specialnode(new time("8:55 pm")); new specialnode(new sometypeyouveneverheardof()); so, being professional programmer, start coding without forethought whatsoever. here specialnode class: class specialnode extends defaultmutabletreenode implements comparator<specialnode> { public int compareto(specialnode sn) { // not not work correctly (read: @ all) // but, sub-par, how type information out of userobject // can cast correctly , call correct compareto method!! return this.getuserobject()....
