In this problem statement we have to perform a deletion operation for deleting the column using the numpy array in Python. Sometimes we need to delete some data from the datasets so that time this problem can be helpful to solve it. Understanding the Problem Numpy library is very useful in data manipulation and numerical calculations. So deleting the column from an array is a very common task. In this problem we will be using the numpy array and delete one column and show the remaining data on the console. So the multidimensional array will be used in this problem. ... Read More
The given problem statement is to perform numeric sorting operations in a mixed pair string list with the help of Python. Sometimes we are required to sort the mixed data type list in Python so this article will be helpful to get the desired sorted form for the given dataset. Understanding the Problem The problem at hand is to perform the numeric sorting in the mixed pair in the given string list. So we will be given a list in which there are the mixed data types like string and integers. So we have to sort them on the basis ... Read More
The problem statement is to find the N random tuples list using Python functionalities. Sometimes we need to generate some random numbers or we can say random tuples in our daily life applications. So in this problem we can generate random tuples using the random library of Python. Understanding the Problem So let us understand the problem first, suppose we have given the limit of the tuple numbers and also the number of tuples we have to generate using the algorithm. To understand this phenomenon we will see the below image − Number of tuples = 5 Minimum value ... Read More
String manipulation often necessitates merging two strings based on shared suffix and prefix sequences; suffices to be at the end, prefixes being at its beginning. This article will show how to merge two strings with suffixes and prefixes using Python language. We are considering two examples where we have two strings and their beginning and ending strings overlapped, the goal is to merge these by appending both strings together without creating redundant overlapped sections. As a result, there will be one string that contains all characters from both original strings without unnecessary duplication or repetition. In the second example, we ... Read More
At hand is the challenge of Python lists - an incredibly flexible data structure capable of holding various kinds of information when dealing with lists within lists (where multiple duplicate entries could exist) duplication is likely. Therefore a Pythonic solution must exist that removes duplicated sublists to ensure each sublist in a main list is unique. In this article, we illustrate how to merge duplicates to a list of lists with detailed examples using different approaches. Merging Duplicates to a List of Lists by Using for Loop Code Explanation and Design Steps − Step 1 − Open Jupyter Notebook ... Read More
Nesting lists in Python refers to multiple lists within one another that can be useful when performing data manipulation tasks; however, occasionally we may wish to change or flatten this nested structure by "flattening a list", in Python terminology meaning changing from multiple hierarchical structures into one single (non-nested) structure where all elements belong under equal scope without hierarchy or hierarchies present. In this article, we will illustrate how to merge nested lists in python using different approaches. Merging Nested Lists in Python Using Recursion Method Code Explanation and Design Steps − Step 1 − Import required module: we ... Read More
The cross product is an operation performed on two vectors in three-dimensional space that results in a third vector that is orthogonal (perpendicular) to the original vectors. In this article, we will see the Golang program to find the cross product of two vectors, here we will explore two different methods. Explanation Let us assume we have two vectors A and B. The cross product of the two vectors can be calculated by the formula: C = A X B. Components of a cross product vector can be calculated by formula: Cx =Ay ⋅Bz −Az ⋅By Cy ... Read More
To represent a given set of items in this problem, the smallest number of subgroups must be present and contain unique members in each subset. In this article, the user will learn how to obtain the minimum number of subsets with distinct elements using a counter in Python. Two examples are depicted in this article. Example one uses a dictionary to manually count the instances of each entry whereas example two uses a counter class to calculate the minimum number of subsets with unique elements. To count the instances of elements in a list, the code makes use of the ... Read More
Lexical order can be used in various applications like sorting algorithms, organizing data in dictionaries or indexes, and string comparisons. In this article, we will explain that how to generate a list of alphabets in lexical order. Lexical order is also known as lexicographic or dictionary order. The words are arranged according to the alphabetical order of their components or letters. In English, there are 26 letters, the lexical order will be followed the traditional ordering of the letters from 'a' to 'z'. Here, we are using various methods to accomplish this task. It will also demonstrate a suitable example. ... Read More
The dot product is a measure of how closely two vectors are aligning in the direction that they are pointing towards. The dot product of two vectors is a fundamental operation in linear algebra that calculates the sum of the products of corresponding elements in two vectors. In this article, we will write a Golang program to find the dot product of two vectors using a loop as well as using the go languages range keyword. Explanation The dot product of two vector is calculated by the formula shown below: DOT PRODUCT = A⋅B =Ax ⋅Bx +Ay ⋅By +Az ... Read More
