Transpose of Array| Numpy tutorial | Data Science | Codin India

Image
  In the last post, we learned about reshaping the Numpy array. In this post, we will learn about the transpose of nd-array. Another very interesting reshaping method of Numpy is the   Transpose()   method.   Transpose is an very important topic when we talk about matrices and arrays. In linear algebra, the transpose of a matrix is an operator which flips a matrix over its diagonal. i.e.  It takes the input Array and swaps the rows and columns value and vica-versa. After transpose rows becomes columns and columns becomes rows.  Let us understand by code:-   Output:- It will convert rows into columns and columns to rows.

Why HTTPS matters? What is HTTPS? - Codin India

  What is HTTP? HTTP stands for Hyper Text Transfer Protocol. HTML is a protocol which allows the fetching of resources, such as HTML documents. It is foundation of any data exchange on the web. It is client-server protocol which means requests are initiated by the recipient on web servers. It transfers data from one webpage to other web pages and from client side to server side and vice-versa.    What is HTTPS? HTTPS is an advanced version of HTTP. Where "s" in HTTPS stands for secure. It is used for a secure connections between web pages. It is used where there is any type of Data Transfers, transaction etc. You should always protect all of your websites with HTTPS, even if they don't handle sensitive data communications. Aside from providing critical security and data integrity for both your websites and users' personal information, Https is a requirement for many new browser features, particularly those required for progressive web pages.

Introduction to Linked List| Data Structure with Python

   Linked List is a linear data structure. Unlike arrays, linked list elements are not stored at a contiguous location. The element are linked using pointers. Why Linked list is used:- Arrays can be used to store linear data of similar types, but arrays have the following limitations. Array's size is fixed. So we must know the highest limit of the array in advance. So we must declare the size of the array first and elements there after.  Inserting a new element is very expensive because the room has to be be created for the new elements and shift the existing elements. Ex :- Suppose we have arrays in sorted order   i.e. [1,2,3,4,6,7]  and we have to insert new element   i.e. [5]   in the array. So in order to maintain elements in sorted order, we have to place that element after suitable element. In this situation we have to shift the element   i.e. [6,7] by position 1. Now  we saw the arrays limitations. Let's understand the advantages of the Linked List over array.  Advantage
