I am new to Python and am looking for any feedback/criticism on scripts I have written for work. This script works as I intended, creating multiple .xls files from a workbook with multiple worksheets. I'm just looking to develop a better understanding of how to use Python. So, please, feel free to rip in to what I've... | stackexchange/codereview |
I wanted a convenient class to easy access the parameters inside. I am using a lot of math in my game; that's why a wanted to access them through x, y and z (for readability). And this is my outcome.
It is a class which lies on top of numpy array. It basically means that I can control a numpy array trough my class. And... | stackexchange/codereview |
I am writing some tests that all follow the same pattern, I feel like repeating myself over and over again, how can I reduce the repetition? The (almost) repeating part is in constructor and the class level variables:

I have created a basic login system that asks the user for a password. Here's a list of what it does:
When you run the code it will open an Inputbox asking you for a password.
There is one criteria: You have to enter a password of 8 characters. If you enter a password with less or more, it will give you an error messa... | stackexchange/codereview |
I wanted to learn some regex, but learning regex is super boring so I decided to write a password validator that will validate a password with regular expressions.
How it works:
You enter a password that has no echo thanks to the getpass library
The password is run against five different validations such as, upper cas... | stackexchange/codereview |
Possible improvements I see are take lastdigit_num and implement arr_{lastdigit_num} since the math behind this is common for most (integers with cyclicity 4 or 2 common to them) integers and reduces repetitive if statements.
For example if num = 23423, then lastdigit_num = 3 and arr_{lastdigit_num} is directly linked ... | stackexchange/codereview |
In this code I tried to swap links in a linked list instead of swapping data.Please Review my code.

Node(T val): data(val), next(nullptr){}
};

I have been working on this particular sub for a while and it was very very slow from the beginning. Compared to my other subs that go through a lot more data the task of this one is almost minuscule. All it has to do is to go through about ~15 sheets and parse through a couple hundred cells. Since this is a fairly com... | stackexchange/codereview |
I started implementing the folowing Matrix class in order to get a better understanding of templates classes in general. For now, it lacks a lot of features, it does very basic things:
addition
multiplication (only matrix X matrix multiplication is available here)
transpose
conversion to a string
Here are some points... | stackexchange/codereview |
I would like to improve code readability and reduce the complexity of my code to improve the maintainability of the source code.
If you have any tips, please say so. I was also wondering if it would be a good feature to add a 2-player option to this game. Currently, the game runs off of a word list in which it randomly... | stackexchange/codereview |
I am fairly satisfied with my solution here but I would definitely appreciate any constructive criticism of my style and design. The basic idea is to use the strategy pattern to simplify assembling a custom procedural generator. I'm using modules rather than classes for improved simplicity of 'mixing' everything togeth... | stackexchange/codereview |
My implementation of BST. Critique will be appreciated!

Here is my approach. Subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.

I tried to code a treemap function in matplotlib, and one of the challenges is auto-fitting text into boxes of different sizes in the treemap, similar to R's package ggfittext.
