The matrix is defined by arranging rows and columns to form an array. The values of a matrix in rows and columns either be characters or integers. There are various method names- dictionary comprehension, for loop, enumerate, and, zip() that will be used to Convert a Matrix to a Dictionary in Python. Using a for Loop and Dictionary Comprehension The program uses the for loop that will iterate the length of the matrix by applying dictionary comprehension. This helps the conversion of the matrix into a dictionary. Example In the following example, we will show the name values of matrix ... Read More
What is a Computer? A computer is an electric device which is developed by Charles Babbage in 1822. It takes input data from the input devices, stores and process it, and produces output in the output devices. The processing is done by the Central Processing Unit. It is designed to perform various operations and tasks depending upon the instructions provided by a user. It can perform a wide range of tasks including word processing, graphic design, gaming, and internet browsing. Components of Computer Hardware Parts - Parts of a computer system which ... Read More
The snake case string is the naming convention where words are instead separated by an underscore(‘-’). The Camel case is defined by two or more words connected together without spaces and the first letter of each word being capitalized. There are various built-in methods in Python such as split(), join(), and, re.sub() that can be used to convert Snake Case String to Camel Case using Python. Let’s take an example of this − Snake Case String − hello_world(having separator i.e. underscore ‘_’) Camel Case String − helloWorld(when we convert the Snake case into Camel case it allows the second ...

The list is defined by an ordered sequence of elements whereas the nested dictionary defines the dictionary include another dictionary. The nested dictionary is required when we want to store large data in a big dictionary. In Python, we have some built-in functions like reduce() and zip() that Convert Lists into Nested Dictionary. For example- Dictionary data communicate the structural content of data which is easier to understand. Syntax The following syntax is used in the examples − reduce() This built-in function in Python follows the functools module to perform a specific operation on lists. zip() The zip() ... Read More
Introduction to Electricity Distribution Electricity distribution refers to the process of distributing the electrical power from generating stations to the consumers. In the first step, electricity is distributed to substations from the generating stations through transmission lines by increasing the voltage level to reduce transmission losses. In the second step, the increased level of voltage is stepped down using the transformers and supplied to consumers by the utility companies. In any industry, more than one voltage level is used for different purposes like 415 V, 690 V, 6.6 kV, and 11 kV. There is a process of voltage conversion ... Read More
In electrical power system, electrical earthing is one of the most important concept used to provide safety and protection to both human and equipment. Electrical earthing, also called as grounding, is basically a path of very low-resistance between the electrical equipment/system and the earth surface. The main purpose of electrical earthing in an electrical system is to provide a safe path for leakage electric current to flow into the earth’s conductive surface to reduce the risk of electrical accidents. Therefore, electrical earthing is an efficient and reliable way of protecting electrical equipment, individuals, and premises against electrical faults ... Read More
Optical fiber technology is defined as technology that is capable to transmit information in the form of light pulses with the help of a high-quality glass or plastic material. It looks like a transparent filament. In this article, we will go through optical fiber, its types, and the differences between them. So, let's begin with the definition of optical fiber. What is an Optical Fiber? Optical fiber is thin a thin or flexible glass or plastic material used to transmit information in the form of light. Glass or plastic serves as a medium to allow the passage of ... Read More
Finding the tag and the HTML tree's content indicates searching the parse tree using BeautifulSoup. There are other ways to accomplish this, but the find() and find_all() methods are the most popular for searching the parse tree. We can use BeautifulSoup to parse the HTML tree with the help of these techniques. One benefit of applying Beautiful Soup is that even when we are moving from another language, it is simple for beginners to learn. It provides excellent, thorough documentation that makes it easier for us to pick things up quickly. Syntax The following syntax is used in the examples ... Read More
The automotive industry is undergoing a major revolution in the method we power our vehicle. The hybrid electric vehicle (HEV) and electric vehicle (EV) are at the leading position of this revolution. The fundamental difference between hybrid electric vehicle and electric vehicle is that electric vehicle relies only on electric batteries as energy source, while hybrid electric vehicle uses both fuel and electricity as the energy source. In this article, we will explore the other major differences between hybrid electric vehicle and electric vehicle. But before that let’s briefly get their overview individually. What is a ...

The dataframe in PySpark is defined by a shared collection of data that can be used to run in computer machines and structurize the data into rows and columns format. The range of rows defines a horizontal line(set of multiple values according to condition) in the dataset. In general, the range sets the lowest and highest values. In Python, we have some built-in functions like filter(), where(), and, collect() to select a range of rows from a dataframe in PySpark. Syntax The following syntax is used in the examples − createDataFrame() This is a built-in method in Python ... Read More
