I'm new to coding and I'm trying to figure out why a simple Pandas code isn't working as expected. The code below should read in the tab delimited file and output the top 5 rows. However, when I run the code, there is no output. Now, if I remove the header and names parameters and use print (df)...

This class encapsulates a 2D Array and a Scripting Dictionary. Values are add or returned from to the Array using a Key and a ColumnIndex, e.g. IndexedArray(Key, ColumnIndex) = Value . The Key is used to get the RowIndex of the Array. The Value is then added to the Array, e.g. Array(ColumnInde...

I am currently making a Tetris clone in Lua through LÖVE, and my current idea for block storage data is as follows: The block's key is a concatenation of its x and y values (for a reason I will describe later) The block's x and y values are also stored in its own dictionary Here's an example ...

currentUserPosts will have a post object with an id that either matches a tempId, an Id, or nothing. If there's a tempId match there won't be an id match and vice versa. This code works but there's something about it I don't like. How can it be refactored? let postIndex; postIndex = currentUse...

I would really appreciate some feedback on this code. It 100% works (as far as I have tested it). Really just looking to improve where I can. All criticisms welcome. Database Template Script: import os import sys from sqlalchemy import Column, ForeignKey, Integer, String from sqlalchemy.ext.dec...

Below I have created a dynamic component AppComponent.html <input type="button" value="One" (click)="setVal('one')"> <input type="button" value="Two" (click)="setVal('two')"> <br> <app-dynamic-component [key]="keyvalue"></app-dynamic-component> AppComponent.ts keyvalue = 'one' setVal(val) {...

How capacity() method work in java? Why we use to add default value 16 to the string length in Capacity() Method in string.

I'm currently in the process of building my own chess game engine and could really use some suggestions on how to make this segment of code for calculating diagonal moves more efficient. (This is obviously only for diagonals going Up-Right) As of now I'm using "Try-Except" to iterate by 1, and t...

Adding the items to the cart is very crucial. I have a session based shopping cart and I need to adjust that shopping cart along with the model because I will need the cart data or cart items in the database either. Here is the models for the cart class Cart(models.Model): user = models.For...

Hey all I have just started with my university project in which I am trying to connect my Temperature sensor in with losant cloud by interfacing with Raspberry Pi After studying this documentation, I tried to modify the code of sensor SHT31 as per mentioned code to connect with losant as follows...

I'm trying to code a simple and concise quicksort implementation in C++11/C++14. I feel like the while loop part is not as nice to read as it could be and it might also have a bug? I was also thinking that it might be nicer to change the function signature to have two iterators as parameters, b...

Description: Given a binary tree and a sum, find all root-to-leaf paths where each path's sum equals the given sum. Note: A leaf is a node with no children. Leetcode Code: class Solution { private List<List<Integer>> paths = new ArrayList<>(); public List<List<Integer>> pathSum(Tree...

The beta test is available from the appstore https://play.google.com/store/apps/details?id=dev.android.buggy Since my previous question about the same project, I have done several improvements: Several UFO:s now Five lives and then Game Over Improved but not perfect vehicle controls Cool bo...

Problem Statement: You are given a read-only array of n integers from 1 to n. Each integer appears exactly once except A which appears twice and B which is missing. Return A and B. Example Input:[3 1 2 5 3] Output:[3, 4] A = 3, B = 4 I wrote the following code : def repeated_number(n...

I've made some code that reads in text files (which hold quite large vectors of word frequencies), which in turn stores each index of a vector within an ArrayList for their specified team (I.E Arsenal vector to the Arsenal ArrayList, Chelsea vector the Chelsea ArrayList, ETC). It then uses a cosi...

I have an application that is sending bytes to a camera over tcp as seems to work fine, however when testing to see what the camera is receiving, the bytes that its sending are not the same as its receiving I believe.First I get the int32 value and convert it to a byte array and check if it is li...

I recently published an iOS control/component called BJDraggable which basically, with a call of a method, enables us to drag a view within its superview boundary. The whole setup works using the UIKitDynamics API. (Scroll to last to see the output achieved.) These are the methods I expose to co...

I am very new programming and am trying to develop a small tycoon game as a hobby project in Unity. This algorithm executes beautifully but if 100+ agents are getting new paths simultaneously there is a significant drop in frame rate. Where should I start with optimizing? I use 4 classes for my ...

My neural network is buggy somewhere, however the reason I am posting here and not stack overflow is because a buggy neural network can still be trained to some degree. Since my neural network is from scratch (and thus pretty long for the casual reviewer), I would like two specific functions to ...

This is a different script from any python script which performs DoS attacks. It's designed to practice parameters fuzzing in the requests (it's requested which parameter you have to fuzz - and after choosed, requests will be made with the selected parameter combined with a 400 random characters ...

I have written a double linked list in Scala. The list should be fixed in size and items are always added to the head. if the list reaches max size then the tail is dropped. This is my code. I want to review this for brevity and functional approach. sealed trait List { var prev : List v...

Without setting SERVER_NAME in the Flask config, url_for with _external=True retrieves the full URL. So I figured the must be a way that Flask (or Werkzeug) retrieves the domain. I dug around inside the url_for function and made this function to get the domain from within a request context. What ...

I am a mathematician attempting to become proficient with C++. At the moment I am learning about data structures. I am now writing a stack dat structure using linked list from scratch. I have tested my class that I wrote and everything seems to be working fine but I want to see if there are any ...

I've tried to implement Kruskal's algorithm. This is the implementation shown at out lecture: KruskalMST(EdgeWeightedGraph G){ priority_queue<Edge> pq; vector<Edge> e = G.edges(); // liefert alle Kanten von G for (int i = 0; i < e.size(); i++) pq.push(e[i]); for (int i = 0; i < G.V(); i++) mark...

I'm building a little script to visualize the probability of rolling a yahtzee (five dice all the same value), and the amount of games it might take to roll a perfect game (13 yahtzee's in a row) Here is the full code before debugging: #include <iostream> #include <random> int main() { st...
