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 ...

Hey Guys! Hope you’re well. I welcome you on board. In this post today, I’ll walk you through PCBA (Printed Circuit Board Assembly) in detail. It's our 4th tutorial in the PCB learning series.
In the 1st tutorial, we studied printed circuit board(PCB) in detail and learned that PCB provides physical support and electrical connection through conductive copper layers for the electronic components placed on the board. We have seen in our previous tutorials that when we place our PCB order on some PCB fabrication house, they provide us with a PCB board without electronic components. We have to solder the electronic components on the board. But now these PCB companies also offer a service to provide finished PCB boards with electronic components attach ...
Hi Guys! hope you are doing great today! We come this time with a complete project to work out together starting from the point at which we sit with the client and receive the logical narratives that represent what they want to implement. We are going to start with a simple project this time and continue increasing the scale and complexity of the requirements through the incoming tutorials. The project we are going to implement today is one of the most common tasks that we can find in every place in our real life which is the control of the garage door. That could be found in private property or commercial buildings or public garages. Too many things need to be controlled in garage doors and several scenarios could come to your mind. However, take it as a rule of thumb that we design our p ...

Hello, fellows, I hope you all are doing great. In today’s tutorial, we will discuss What is Electromagnetic Induction. In 1831 Micheal Farady (he was British scientist, most of his work was in electro-chemistry) gave his famous law electromagnetic induction. In 1832 after Faraday, Joseph Henry who was an American scientist working on Faraday's findings and provide practical uses of electromagnetic induction. First time in August 1831, Farady performed an experiment for electromagnetic induction. To perform his experiment he takes 2 wires and one ring of the iron, then he wound these 2 wires on the opposite sides of the ring. By this arrangement, he created transformer-like structure.
At the terminals of the first wire, connect the battery and the ...
Socket size is the main factor for homeowners, DIYers, and also for mechanics and enthusiasts. The socket size mentioned in numbers helps to use tools for certain projects, like for bolt head tightening or furniture assembly. In this tutorial, we will cover details for socket size charts
and different socket sizes that help to find differences between SAE and metric sockets and wrench sizes. So let's get started.
What is a socket?
The socket is a tool or instrument that is connected at one end of a ratchet that is used for tightening or loosening fasteners through turning. The working of the socket is performed in conjunction with ratchets.
The socket snaps on one end of the ratchet due to the square drive connector. The other end socket is fitted at the position with a fastener.
Rat ...
Hey Guys! Hope you are doing well. Today, I'll unlock the details on How to Create a Jet Fighter Model In AutoCAD.
The drawings were published on the Internet * and represent several types, 22 cross sections (fuselage forming elements) perpendicular to the longitudinal axis of the fuselage, and a number of additional sections (Figures 1 and 2).
The accuracy of the drawings, of course, is not high, because these are just data for the modelers. We will have to believe this data, take them for truth in the first instance and start creating a digital prototype.
How to Create a Jet Fighter Model in AutoCAD
Where to begin? From converting JPEG to DWG (to increase their self-esteem, this tedious process can be called manual vectorization of vector gra ...
Metalworking, a craft embedded in the core of human civilization, has played an important role in shaping our history and technological advancements. From the ancient artisans who meticulously forged metal objects to the modern engineers pushing the boundaries of materials science, the art of metalworking has stood the test of time. Let’s explore this intricate craft, tracing its evolution from ancient times to the cutting-edge innovations of the modern era.
A Glimpse into Metalworking's Illustrious Past
The tale of metalworking begins in the annals of ancient civilizations such as Mesopotamia, Egypt and China, where skilled craftsmen honed their techniques to manipulate metals for tools, weapons and adornments. Through hammering, casting and forging, these early metalworkers laid th ...
Hey Fellas! Welcome to our website. Today, I am going to share the 2nd chapter in the PCB learning series, where we will discuss Single-sided PCB in detail. In Single-sided PCB, the copper layer is present only on one side of the
PCB and the other side is used for incorporating electronic components. This type of PCB is used in simple circuits with low component density. The conductive tracks in single-sided PCB can't cross each other because of a single copper layer.Let's dive in and explore more,
I'll try to cover every aspect related to Single-sided PCB:
Single Sided PCBSingle-sided PCB, also termed as single-layer PCB(though there's a slight difference), is the simplest type of PCB where the copper layer is present only on one side of the b ...
