Set followlinks to True. This is the fourth argument to the os.walk method, reproduced below: os.walk(top[, topdown=True[, onerror=None[, followlinks=False]]]) This option was added in Python 2.6. EDIT 1 Be careful when using followlinks=True. According to the documentation: Note: Be aware that setting followlinks to True can lead to infinite recursion if a link points to … Read more
Use reverse_iterator instead of iterator. Use rbegin() & rend() instead of begin() & end(). Another possibility, if you like using the BOOST_FOREACH macro is to use the BOOST_REVERSE_FOREACH macro introduced in Boost 1.36.0.
Here’s something you can use. Just replace the printfs with what you actually want to do. #include <stdio.h> int main() { int x[3][3] = {1, 2, 3, 4, 5, 6, 7, 8, 9}; int n = 3; for (int slice = 0; slice < 2 * n – 1; ++slice) { printf(“Slice %d: “, slice); … Read more
The problem is that your using the next traversing function rather than nextAll $(“button[disabled]”).nextAll(“.error”).text(“this button is disabled”); When you use next its just looking at the “next” element which is <span>no overwrite</span> Next all looks at all siblings that are next
Yes, you can traverse a Standard Library map. This is the basic method used to traverse a map, and serves as guidance to traverse any Standard Library collection: C++03/C++11: #include <cstdlib> #include <map> #include <string> using namespace std; int main() { typedef map<int,string> MyMap; MyMap my_map; // … magic for( MyMap::const_iterator it = my_map.begin(); it … Read more
I made a research on a small cache of web pages in 1000 dirs. The task was to count a total number of files in dirs. The output is: os.listdir: 0.7268s, 1326786 files found os.walk: 3.6592s, 1326787 files found glob.glob: 2.0133s, 1326786 files found As you see, os.listdir is quickest of three. And glog.glob is … Read more
How about Morris Inorder tree traversal? Its based on the notion of threaded trees and it modifies the tree, but reverts it back when its done. Linkie: http://geeksforgeeks.org/?p=6358 Doesn’t use any extra space.
The best way is to use the node object directly by using its attributes property. The only difference in my solution below compared to others suggesting this method is that i would use .each again instead of a traditional js loop: $(xml).find(‘item’).each(function() { $.each(this.attributes, function(i, attrib){ var name = attrib.name; var value = attrib.value; // … Read more

Here’s a fully parametric example: data Weird a = Weird a (a -> a) instance Foldable Weird where foldMap f (Weird a b) = f $ b a Weird is not a Functor because a occurs in a negative position.
