Hello! Welcome to the next lesson in this Python course. In the last session, we learned about python tracebacks and how to deal with them. A dictionary, like a list, is a collection of items, and we'll look at that in this tutorial as well.
What will you learn?
This tutorial introduces you to the fundamentals of dictionaries in Python and teaches you how to work with dictionary data. After reading this article, you should be able to tell when and how to utilize a dictionary as a data type.
Characteristics of Dictionaries and lists
Both can be changed (mutability).
A dynamic relationship exists between them. When needed, they're able to expand and contract.
Both are nestable. Another list can be ...
Welcome to the tenth lesson of our python course. In the previous tutorial, you learned about syntax errors in Python, and in this lesson, we will look at one more error notice that is given by Python when there is an error in your code. So, without further ado, let's get started.
Any time an exception is thrown in your code, Python shows you the stack trace. If you don't know what the traceback output is showing you, it can be a little overwhelming. Python's traceback, on the other hand, provides a goldmine of information that can assist you in figuring out why an exception was triggered in your code and fix it. It's essential to learn how to use Python traceback to become a better coder.
After completi ...
Welcome to chapter 9 of our python tutorial. In the previous chapter, we looked at frequent examples of invalid Python syntax and learned how to fix them. Up to this point, you are well aware of errors that may occur in your Python program and how you can solve them easily and quickly. Therefore, in this tutorial, we will look at a few more causes of syntax errors and zero-error divisions.
Mistaking Dictionary Syntax
As you learned before, omitting the comma from a dictionary element can result in a syntax error. In Python dictionaries, the equals symbol (=) is used instead of a colon to separate key and value pairs.
This error message is once again useless. In this case, the repeated line and caret come ...
Hello geeks, welcome to our new project. In this project, we are going to make a very interesting project. I think most of us have seen the scoreboards in sports, after looking at that, have you ever wondered about the working of it. Therefore, this time, we will be making something like that only with some extra features. So basically that score board is nothing but a counter which counts the scores. Most of the geeks who have an electronics background or have ever studied digital electronics must have heard about the counter.
Here, in this project, we are going to make an Up-Down counter. A simple counter counts in increasing or decreasing order but the Up-Down counter counts in increasing and decreasing order, both depending upon the input it h ...
Hey readers! I hope you are doing good and learning something. Have you ever thought about electric vehicles, which are rechargeable and run on a battery? Now, it is possible, and today, we will discuss electric vehicles.
All over the globe, EVs have made a major difference by being a cleaner and cheaper way to travel than gasoline and diesel cars. Unlike cars with engines, electric cars are environmentally friendly because their engines use rechargeable batteries and give out no emissions. The rise in buyers and producers of EVs is thanks in part to new kinds of batteries, better motors, and certain actions taken by the government.
Because of their various operating systems, Battery Electric Vehicles (BEVs), Plug-in Hybrid Electric Vehicles (PHEVs), Hybrid Electric Vehicles (HEVs), and ...
Hi Everyone! Glad to have you on board. Thank you for clicking this read. In this post today, I’ll cover the Role of Cloud Computing in IoT.
Digital transformation has gained momentum in the past few years, the reason traditional technologies are becoming obsolete over time. Now organizations are incorporating modern technologies into their business model at an accelerated pace. These technologies produce the influx of data and at times it becomes very difficult to process and handle that data, thanks to cloud computing that has made the handling of data easy and effective. You don’t need traditional data centers anymore to store and process information. Everything will be taken care of remotely in the cloud with data centers.
Not to mention, this is the era of automation. Companies striv ...
Product designers nowadays have access to various technologies for creating multiple prototypes. These include traditional methods such as pen-and-paper sketching and cutting foam blocks, as well as more modern technologies such as 3D printing and CNC machining service.
However, today we will focus on the additive manufacturing technique and what you should look for during your search. Numerous businesses embrace the technology by delegating tasks to professional 3D printing services.
In the globally competitive environment, adding a supply partner to the company's value chain is the way to go because the technology is capital-intensive to implement. To help more businesses adopt the technology, we've created a simple guide to help them select the ...
3D printing is one of the most promising technologies in recent breakthroughs. One of the most inherent benefits of 3D printing is additive innovation; it opens up an entirely new way of creating products and provides numerous benefits over traditional fabrication techniques.
Nowadays, more businesses across many industrial sectors adopt 3D printing as a viable alternative to subtractive manufacturing (acquiring machined parts online) and injection molding. We'll look at the benefits of 3D printing and how you can use this production method to benefit your company. Is it worthwhile to use 3D printing for your project?
Affordability
One of the best aspects of 3d printing is the reduced labor costs. Operating costs heavily influence the quantity of ...

Hi Guys! Hope you’re well today. Thank you for clicking this read. In this post today, I’ll walk through Cloud Computing Advantages.
Growing a business requires keeping up with modern technologies. And cloud computing is no different. Even though it’s not a new term and has been around for a long while, it still encompasses a huge potential to effectively run and manage business operations. Cloud computing is the provision of computing resources over the internet. These resources include storage, processing power, and databases.
Integrating more technologies (like IoT, AI) into the business models means it opens up opportunities to produce a large amount of data. And it’s very challenging to store and process that data on on-site data centers. Th ...
