I am trying build a tree (dictionary ) from input numbers. My main criteria for the tree is all the nodes in a level are in a same range. ( a series of data from parent) I think you will get idea from my examples- Please see the example I tried to build a tree initially. This will work only

How to create a list that represent the number of times a given item was shown?

If anyone can point out my error, and inaccuracies it would be lovely! I have made it so that each node gets
python: class vs tuple huge memory overhead (?)
I’m storing a lot of complex data in tuples/lists, but would prefer to use small wrapper classes to make the data structures easier to understand, e.g. would be preferable over however there seems to be a horrible memory overhead: and Why? is there any obvious alternative solution that I didn’t think of? Thanks! (I know, in this example the ‘wrapper’
Recursive diff of two dictionaries (keys and values)?
So I have a python dictionary, call it d1, and a version of that dictionary at a later point in time, call it d2. I want to find all the changes between d1 and d2. In other words, everything that was added, removed or changed. The tricky bit is that the values can be ints, strings, lists, or dicts, so
Python Implementation of the Object Pool Design Pattern
I need an Object Pool, and rather than implement it myself, I thought I would look around for a ready-made and tested Python library. What I found was plenty of other people looking, but not getting many straight answers, so I have brought it over here to Stack Overflow. In my case, I have a large number of threads (using
