You’ve probably been asked a question before and your answer was

And that’s because there is already a habit formed, but what is a habit? And when to tell there is a habit involved? And how can you create a new habit and quit a bad one?
Before answering such questions, we need to know why a habit is important, and can anyone develop one?

The importance of a habit

pandas was initially released in 2008 written in Python, Cython, and C. Today, we’re comparing the performance of this well-known library with pypolars, a rising DataFrame library written in Rust.

$ cat >> fake_users.csv


Now, let’s compare the sorting algorithm…

Want to write a technical book or document your project?

Here I’ll walk you through how you can do that with python and sphinx. You can build content of tables that can contain sections to the chapters of your book. I will show you a case study to know how to insert images, hyperlinks, mathematical formulas, syntax highlighting for your favorite programming languages, and more.

Assuming you have some basic knowledge of python, let’s dive in and see what sphinx can do for us.

On January 14 this year, Google bought Fitbit (a wearables company) for 2.1 billion dollars!

The question is why a big name like Google buy a smaller company like Fitbit and such an acquisition is worth billions of dollars?!

The same question goes for many big names and another question comes up because these big companies have very talented engineers who are able to replicate what small ones can do. So what makes big companies think about buying more in the first place?

Reasons may differ from one company to another; it may also interchange with another reason, but we…

Learn the fundamentals of programming by asking questions

Photo by Jose on Unsplash

What programmers do when they solve a problem is that they convert the logic to questions and then try to find answers to those questions.

We always do these steps in any programming problem:

  1. Convert the business logic to questions
  2. Be able to find answers to these questions in code

This article is for complete beginners in Python and/or Rust, we’ll see a case study and we’ll try to solve the problem involved by asking questions

And will go through each line of each code written in Python and Rust to be able to answer the questions raised.

Let’s do…
