I'm adding/editing the docstrings to my custom tkinter modules. These contain classes that are subclassing tkinter objects as well as each other. I'm trying to follow PEP 257, but applying to this case feels forced and awkward. Any criticism of how I'm going about this is welcome, but these items...
According to the zen of python Explicit is better than implicit.
I am thinking of naming any of my functions that may explicitly throw en exception with a prefix try.
For example
def try_something():
# do something
if some_condition:
raise Exception()
What are the pros and c...
I wrote a utility for generating and saving sessions in a MongoDB database as well as checking the session to make sure it's valid.
I'm a beginner when it comes to promises and I have a feeling that either I'm using them improperly or I'm not taking full advantage of them.
Here's the session ut...
I recently overhauled my problem 23 solution to move it from an imperative style to a functional style and tried to increase its speed. However, the performance is still slow. I have clocked this solution at 58 seconds, and the older imperative solution at 64 seconds.
I am mainly hoping for feed...
I have a basic bit stream which uses a byte array and a index position to read and write bits.
My write method takes an int value only and the number of bits and applies this to a byte array in the bit stream.
My read method takes the number of bits i wish to read and an reference to an int to ...
I created a program that measures the time for the Bubble Sort Algorithm to sort a list of numbers. This is my code here:

{
std::ifstream SortFile("Number_Sort.input");

My laptop is old, so i decided it would be good if my laptop would scream at me if i kick power brick, so i would make the brick work again, and not notice only when battery runs out and i loss all the data (battery meter is not to be trusted).

So what I am trying to do is to find count of alternating numbers such that it alternates with -ve and positive sign for eg: 1 -2 3 -4 would get me 4 3 2 1 as from 1 to -4 including the two numbers there are 4 numbers. Simillarly for 1 1 -3 2 would get me 1 3 2 1 Now I have the code but I cannot ...

I am working on a database migration tool, which should be database agnostic: https://github.com/adhesivee/database-migrator
When creating/updating a database the columns can have some optional parameters. This is how the API look like:

I am trying to brush up on Java after not programming for a few years. The idea behind this code is simply to get used to object oriented programming, modularization techniques, and basic arrays. Any comments and critiques are obviously welcome!
Here is my code:

This is the revised code after incorporating the suggestions from user Roman Susi.
Link to the previous post here.
Notable edits: I have factored out the bigger functions into smaller tasks. The functions and variables have(hopefully) less ambiguous names, and the JSON object is now deepcop[ie...

I'm trying to get better in go by make a 3D game. (Yes, I know that's a lot of work but I'm doing it for experience and not to make a profit.) And I want to improve the loading of the OBJ Files as this slows down the game quite a lot. As you might notice I tried to remove all transient objects fr...
I am a part of a student project to build a website that offers users a way to search for items in an online library catalog that are all part of some collection. The details of the project are not super important. I am responsible for writing the "backend", which in this case is just writing a...
I'm learning about inheritance and polymorphism in my CS class and thought it'd be a good idea to find something I could apply myself to. I have a lot of ideas, and sometimes there's things I want to do and things I don't want to do. Why not leave the decision-making up to Java?
I'm looking for ...

This is my first shot at asyncio. I'm looking for any pointers you might have. Especially:
Are there any race conditions?
This code doesn't scale as expected. In my project I need to call foo 4k times.
As a background thread I need to make 4k network calls (foo, which is a third party func...
I'm trying to create a robust function that receives a string -- typically a paragraph or two -- and the max number of characters in the output. One condition is to make sure that we return full words and never cut on in half.
Here's the code I have and I feel it needs to be improved.

After reviews of my previous codes 1st, 2nd learned many new things. So with those in mind, this is my solution for another question.
Question: Write a program that ask user for list size and values and find largest and smallest no, even no, odd no?

The Problem:
My C# code that renders the mandelbrot set does so in ~450ms, while my c++ code using MPFR and MPIR takes ~10,800ms at 5 iterations. Both of these times are fairly slow, but 10 seconds is glacial for rendering the set. I am aware that this question, this question, and a slew of othe...

Im trying to optimize my code and in the process of doing that I made a class Query_builder that handles SQL queries. That class has couple of methods: ExecuteScalar (execute scalar queries that mainly return int as a type), FillDataTable(used to fill Datatable with data from SQL tables) and the ...
The following is a code snippet taken from a pong game.
My main concern is the number of if statements. It looks inelegant and there is duplicated code in many places. Furthermore, everything is in the main function. But I'm not sure how or even if it should be refactored. Should there be a sep...
I have an unusual setup. I have an AT89S52 microcontroller in which its UART is used by the PC. I needed a way to make a second UART based device work with it, so what I decided to do was make a UART to SPI converter using an AT89C2051 due to its smaller size and smaller cost. Now I have some tro...
