I initially posted a question on SO. I have come up with an answer for the same. Basically, given two dicts of models and parameters, user can create an object, and get the report in 5 steps.
Following is the code.

I have a very basic method at the moment that fills text boxes with data relevant to the selected company. I load the data into a DataGrid using this method;

This is a question from the book "Cracking the Coding Interview".
Write a method to decide if two strings are anagrams or not
I think interviewer will not be convinced with this solution because here it is no test of logic. Please help me to optimise this solution.

I have a requirement to validate file names related to architecture after they are uploaded. Once they have been uploaded I must warn the user if the file name is not standards compliant.
What's in a name
To be standards compliant a file name must consist of 7 parts after the extension is removed from the name, and:

I frequently use MathJax, and often I need to write matrices. Since writing matrices using MathJax is very tiresome task, I decided to automate it.
Code:

import pyperclip

def __init__(self, matrix, n = None, m = None):
if matrix == None:
self.matrix = n... | stackexchange/codereview |
The purpose of this code is to generate the CSR and the Private Key.
The scenario is that we have some clients for whom we run websites and for the SSL component we want to have a page on our site where they can input the fields like domain name, company name etc and then the system will generate the CSR (and return it... | stackexchange/codereview |
Greetings.
I'm a newbie python developer who just started using PyQt5 as his major GUI development tool.
Because of this, I have started a side project known as NyvoAI, just for gaining more knowledge in the branch of GUI development with PyQt5.
The main project goal was to gather multifarious Artificial Intelligence t... | stackexchange/codereview |
Currently I am working on some kind of mechanism which will be able to monitor directory and when file with extension .pdf appears I need to mock some kind of processing on this file. Let's say, renaming and creating log file with the information of this processing.
And as I wrote it is some kind of mock. So informatio... | stackexchange/codereview |
I have this piece of code which given a list returns another list which combines every element with every other element (without repetitions) using a given function as a combiner. I came up with three different version (2 of them listed below, fastest to slowest), and now I'm asking for help to optimize it/them even fu... | stackexchange/codereview |
I am learning to write a multi-threaded linked list class implementation with basic functionality such as push to front or back, pop_back and read. I came up with this implementation:
#include <iostream>
#include <thread>
#include <mutex>
std::mutex m;

I would like to modify my shortest path finding code to use multithreading and improve its performance. The algorithm must be able to work with negative weights, and as a result, we cannot use Dijkstra's algorithm. Instead, our approach combines three algorithms: Bellman-Ford, SPFA_Queue (shortest path fast algorithm, ... | stackexchange/codereview |
I'm currently learning python with an udemy course. I wrote this code, which is meant to be a higher lower game, where the second answer always stays. As far as i tested it my code is working fine, but i feel like many solutions are bad. Its just felt weird coding some of the solutions, but i cant come up with better s... | stackexchange/codereview |
Background
I am currently participating in a tic-tac-toe coding challenge. During their move, each participant is given the board state and their team, X or O. The blank board is:
[[' ',' ',' '],[' ',' ',' '],[' ',' ',' ']]
With 'X' and 'O' being added to the board, for example:
[[' ',' ',' '],[' ','X',' '],[' ','O'... | stackexchange/codereview |
I've posted an excerpt from my Nginx configuration with the hope that someone can give me advice on anything I've done wrong or could do better. Please note that the below config works, but has been edited for brevity.
The area I'd like you to focus on is TEST1 and TEST2.
TEST1 is redirecting any requests to /folder/... | stackexchange/codereview |
I want to map functions from my functions library (Map called as chain) to input string str. Also that functions (Twitter.removeRT, ...) are regex which replace substrings in input str. I think it is better to save that regex-functions in Map like in my example.
So, the code:

I've written a fairly simple script in F# which reads structured data from binary. I've avoided using the built-in .NET BinaryReader class because it's stateful in that it maintains its index in the stream. Instead I wanted to write a purely functional implementation. I'm doing this for my own personal learning so YAGN... | stackexchange/codereview |
I am working on the largest Java program I have undertaken to date and feel uncertain in my current code practices. I think that I state and repeat things that don't need to be which can become a headache as development goes on. Specifically, in my GridBag Constraints. I have worked with GridBagLayout before and had go... | stackexchange/codereview |
