How can I create path folders from list

I have a list that contains folders names with paragraph numbers (extracted from a word file with pydocx)

ANSWER

I will explain everything here:

Verify if the first value of every element in your list is a file or a directory.
If the element is a file add it into your paths folder using your parentStack. I used a tuple for that (Number of the directory, Complete name of the directory, If the directory it is in your path list of not), for example, ("5.5.", "5.5. Directory Example", False).
If the parentStack is empty and your element is a directory add it into your stack.
If your stack is not empty check if the last element of your stack is the parent directory of your current element. If it is the parent add it into your stack. If it does not, remove the last element and check if that element has been added into your paths list.

There is the code:

QUESTION

how to give directions for a Pong game from outside the game loop?

Asked 2017-Mar-27 at 20:01

I am trying to use a simple Server/Client socket to control the paddle in the game. The idea is to make the client able to control the paddle by sending directions to a server which will pass this directions to the game. so i have created to threads one to be listening for client's directions and storing them in a varibale, and the other thread is for running the game. The problem is that when the client send the lettre "z" (to move the paddle up) the game starts but he send another lettre the game crushes.

I don't know if i have explained enough the problem, I'm new in python and i'll appriciate your help to tell me how to fix the problem !

Here is my code :

You are waiting for 1024 bytes of data, and it doesn't arrive, so the thread hangs. Either change that to 1, if you are sending key-by-key, or use non-blocking sockets.

You also don't use new socket to connect to the listening one. You need two of them. One is server, one is client.

Here is what you want, a little bit simplified. It only changes the window background. You should stick with threading module if you are seriously planning a networking game. It gives you more flexibility than low-level threads. But this code is good enough to see how to do what you want. Also, there is no timestamping and synchronization. When using this on localhost and local ethernet it'll work fine.

So the problem you are likely having is that the attributes are not formatted correctly in your code - and then if you look at the results in a browser DOM inspector, for instance, the browser will do it's darn best to understand and "fix" the wrong attributes you gave it...

So you should be expecting:
