The following works properly:

def walk(dir, dent = 1):
    print ">" * dent, dir
    for item in os.listdir(dir):
        if os.path.isdir(dir + '\\' + item):
            walk(dir + '\\' + item, dent + 3)
        else:
            print " " * dent, item

print "\n\n\n\n"

walk("C:\\program files\\python\\")

| I'm learning Python - just for the hell of it really - but I don't
| understand what's going on here:
|
| import os
|
| def walk(dir, dent = 1):
|     print ">" * dent, dir
|     for item in os.listdir(dir):
|         if os.path.isdir(dir + item):
|             walk(dir + item, dent + 3)
|         else:
|             print " " * dent, item
|
| print "\n\n\n\n"
|
| walk("C:\\program files\\python\\")
|
|
| If I run the above code, it throws an "OSError: [Errno 3] No such process"
| error at the 'for' statement.
|
| This is on NT 4 and the os.listdir(whatever) works fine interactively.
|
| I know there's a walk function already but I'm trying to get the hang of
| this.
|
| Thanks for any help.
