Welcome to chapter 8 of our python tutorial. In the previous chapter, we learned about Python numbers and how to use them in expressions. Throughout this chapter, you'll look at frequent examples of incorrect Python syntax and learn how to fix them.
At the end of this tutorial, you will:
Distinguish incorrect syntax in Python
Get familiar with SyntaxError tracebacks
Fix improper syntax or avoid it altogether
In Python, what is an invalid syntax?
Before transforming your Python code to Python byte code, the interpreter parses it. The parsing stage is where the interpreter searches for any instances of improper syntax in the program. Using the wrong syntax in your Python code will lead the interpreter to be unable to decipher it. The inter ...
Hey Pals! We hope you are doing Great. Today, we are going to design another application of DLD Logical Gates i.e. Half Subtractor. In our previous lectures, we covered Adders in detail, where we studied both Half Adders & Full Adders. Now its time to discuss its reciprocal i.e. Subtractors.
In this session, we'll seek the answers to the following topics:
What is Half Subtractor?
Working Principle of Half Subtractor.
Truth-table of Half Subtractor.
Simulation of Half Subtractor in Proteus using three Logic Gates.
Designing of Half Subtractor with NOR gate.
So, let's get started:
What is Subtractor?The functionality of Subtractors is exactly the opposite of Adders(we discussed in previous lectures) and defined as:A Subtractor is a simple DLD Electronic circuit, d ...
Hi Mentees! Welcome to another electronic tutorial about the 555 Timers. We are working on Proteus and in the present experiment, we'll design the circuit of Pure Sine Wave Inverter. Inverters are the opposite devices to rectifiers. We'll show you the meaning of this sentence in action Yet, before experimentation, we have to learn some predominant concepts about the experiment. So, We'll go through the following topics:
Introduction to Pure Sine Wave Inverter.
Components used in the circuit of Pure Sine Wave Inverter.
Working of the circuit of sine wave inverter.
Circuit simulation of pure sine wave inverter in Proteus.
Introduction to Pure Sine Wave Inverter
In electronics, we examine the output of devices in the form of waves. Basicall ...
Hi Mentees! I welcome you on behalf of The Engineering Projects. In this section of this DLD Logic gates series, we are discussing different applications of logic gates. We have discussed DLD Adders and Subtractors in our previous lectures and now it's time to have a look at DLD Multiplexers.
What are Multiplexers?
What are the types of Multiplexers?
What are the two input Multiplexers?
How can we simulate the Circuit of 2 to 2 MUX in Proteus ISIS?
How can we use the 2 to 1 MUX as OR, AND and NOT gates?
What are Multiplexers?
When I heard the word Multiplexer, I thought that as Adder adds numbers, Subtractor subtracts numbers, similarly, the Multiplexer will multiply binary numbers but that's not the case. Multiplexer is defined as:
A Multiplexer(also called MUX or ...
You must have heard about the VPN. It's a much common phrase these days. Many teenagers use this service to browse online, stream the content and get the location prohibited services online, but the actual meaning of VPN is a lesser-known fact and why VPN was introduced is rarely known. In this complete guide about VPN, you'll learn everything about the VPN- the intro, history, usage, types and benefits.
Introduction to VPN
VPN is pronounced as Virtual Private Network. As its name suggests, VPN is a private network connection that serves the purpose of data sharing, privately, among several connected devices. All the computers, mobiles, laptops and other devices connected through this virtual private network can share the data with secured encrypt ...
Hello Engineers! Welcome to the board. We hope you are having a good day. In this tutorial, we teach you about Pulse Width Modulation. We'll discuss some important points about the topic. Let's have a look at the Topics of the tutorial:
What is Pulse Width Modulation?
What is 555 Timer?
how does 555 Timer is used in the Pulse Width modulation circuit?
How do we design the circuit of Pulse Width Modulation in Proteus ISIS?
In addition, you will have some useful information bout Pulse Width Modulator in DID YOU KNOW section.
Pulse Width Modulation
Pulse width Modulation is a useful technique in the world of Modern Electronics. Let's have a look at the information about Pulse Width Modulation.
Abbreviation of Pulse Width Modulation
The Abb ...
Hey fellow! Welcome to the next episode of the Python series, where we are learning the basics of Python to implement them in deep learning. In the previous lecture, our focus was on string data types. With the practical implementation of TensorFlow, many interesting points were discussed in depth. I hope you completed the home task that I assigned you during that lecture. Today, we are moving forward with the next data type, which is a sequence. You will know the different sub-groups of this data type as well in the next lecture, but today, the focus will be totally on the list because, once you understand them well, other data types of the sequence will be at your fingertips. Yet before starting, it's time to look at the content that you will learn today:
What is a sequence?
How do you ...
Hello students! Welcome to the new tutorial on Python. We all know that Python is one of the most popular programming languages, and there are hundreds or thousands of developers that are earning a handsome amount with the help of this easy programming language. In the previous lecture, we studied the range in the sequence, and in the present class, our concern is having the command on the sets in Python. We know you are curious about the set's details, but before this, I want to share the list of topics that will be covered in this class.
What is a set in the Python programming language?
What are some properties that distinguish the set from other data types?
What is the mutable data type, and how is it related to the set?
Introduction of the Jupyter notebook.
Can we have duplicate ...
Hi Mentees! I hope you all are having a Productive Day. In our previous lecture, we discussed the DLD Basic Logic Gates and simulated them in Proteus. Today, we are going to use these standard logic gates and will design another logic gate named NOR Gate and will also simulate it in Proteus.
In this tutorial, we'll learn the following concepts:
What is a NOR Gate?Why NOR is called Universal Gate?
How to derive other Gates through NOR Gate?
Advantages of NOR Gate.
Let's begin the exploration:
What is a NOR Gate?"NOR gate is designed by inverting the output of an OR Gate, so it gives a HIGH output, only when all the inputs are LOW."In simple words, a NOR Gate has an OR Gate followed by the NOT Gate, as shown in the below figure:

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 ...
