I wish to ignore some directories in my os.walk().
I do:
folders_to_ignore = ['C:\\Users\\me\\AppData\\'];
def find_files(directory, pattern):
for root, dirs, files in os.walk(directory):
dir[:] = [d for d in dirs if not is_folder_to_ignore(d)];
for basename in files:
if fnmatch.fnmatch(basename, pattern):
filename = os.path.join(root, basename)
print("filename=" + filename);
I get:
File "C:\Users\me\workspaces\pythonWS\FileUtils\findfiles.py", line 29, in find_files
dir[:] = [d for d in dirs if not is_folder_to_ignore(d)];
TypeError: 'builtin_function_or_method' object does not support item assignment
Any ideas?
Thanks.

OS. walk() generate the file names in a directory tree by walking the tree either top-down or bottom-up. For each directory in the tree rooted at directory top (including top itself), it yields a 3-tuple (dirpath, dirnames, filenames).
walk() never changes the current directory, and assumes that its caller doesn't either.
listdir() method returns a list of every file and folder in a directory. os. walk() function returns a list of every file in an entire file tree.
Python's built-in os. walk() is significantly slower than it needs to be, because – in addition to calling os. listdir() on each directory – it executes the stat() system call or GetFileAttributes() on each file to determine whether the entry is a directory or not.
You're using dir which is a built-in, probably you mean dirs
change this
dir[:] = [d for d in dirs if not is_folder_to_ignore(d)]
to this
dirs[:] = [d for d in dirs if not is_folder_to_ignore(d)]
