Dictionary in python is a collection data type that stores information in the form of keys which have their corresponding values. It is unordered in nature and the stored data can be manipulated i.e.; it is changeable. We use dictionary to perform various operations, its application extends in the field of data base management, machine learning and web framework development. In this article we will perform a basic dictionary-based operation explaining the different ways in which we can copy a dictionary element from an already existing dictionary. Before we dive deep into the topic, let’s quickly go through the ... Read More

When we are dealing with speech-based operations or creating a letter analysis table, we need a series of ordered alphabets. We can use python programming to perform such operations. Python offers numerous libraries and methods to create an ordered sequence of alphabets. We can contain these alphabetic sequences with the help of several collection datatypes such as lists, tuples dictionaries etc. In this article, we will be performing a similar operation to print a list of alphabets initialized in the correct order. The produced list will contain all the 26 English language alphabets. Before we dive deep into the discussion, ... Read More

Machine learning and artificial intelligence are the trendiest field of advancements. We create machines with a vision to produce next generation models. These models learn from the existing data and modify itself. There are multiple fields involved when it comes to the construction of such machines. Not just coding but mathematical equations, vectors and weights are also used. There are numerous programming languages that are used for creating the framework and models for a machine including python. In this article, we will discuss and try to find out why python is considered a good programming language for AI and ... Read More

Python is a very powerful programming and it is heavily used in various fields. Python is considered to be the most popular programming language among developers at the moment and the reason for the rising popularity of python is the efficiency and simplicity it offers. In today’s modern digital era, data is everything and the management of this data is the biggest challenge for the tech powerhouses around the globe. When a machine is created to think and learn on the basis of past experiences, data complexity is inevitable. So, the smart move is to use a programming language ... Read More

“Which programming language is the best?” this is the most popular and debatable question in the programming world. The answer to this question is not linear or simple because technically every programming language has its own pros and cons. There is no “best” programming language because each language holds a slight advantage over other languages depending upon the problem. When we talk about machine learning, undoubtedly python is a highly preferred language but there are certain factors that should be considered We will talk about these factors in detail but before we dive deep into the discussion, let’s quickly understand ...

In this article we are going to change all lower-case text to upper-case text in a file in java. Suppose the text file contains the following data − “Merry and Jack are studying.” Then after updating the text file with specific value the result will be − “MERRY AND JACK ARE STUDYING.” This modification is done with the help of toUpperCase() Method. It belongs to the String class in java. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose the original content of the ... Read More

Carnot cycle is the most fundamental gas power cycle. This is the cycle which acts as a benchmark for any engine cycle. Each and every engine cycle efficiency is checked against the Carnot Cycle. If an inventor develops a new engine cycle, then it has to be validated against the benchmark, i.e., the Carnot Cycle. All thermodynamic cycle has an upper limit established by the Carnot cycle. It comprises of two reversible adiabatic processes and two isothermal processes, in total four processes. Isothermal processes involve the addition and rejection of heat, whereas reversible adiabatic processes involve work interactions. A ... Read More

Golang has a large range of internal packages to work with the directory. The directory in which the application is operating is known as the current working directory. Here we can use the OS packages as well as the path/filepath package of Golang to get current working directory. In the OS package we can use os.Getwd() function to the current working director. Whereas in path/filepath package we can use filepath.Abs and filepath.dir to get the filepath of the current working directory. Method 1: Using os.Getwd() function This method uses the os.Getwd function from the os package to get ... Read More

In go we can use io and os package to perform various operations with file. In this article, we are going to use ioutil.readfile function to read the file and then the string function to convert the file data to string. From OS package we are going to use os.open to open the file and use string operation to convert the data to string. Method 1: Using io/ioutil package In this illustration, the file's contents are read into a byte slice using the ioutil.ReadFile function. The byte slice is subsequently transformed into a string using the string function. The contents ... Read More

Golang has packages like os, io, and Archie/zip that can be used to read and print all the files from a zipped file. A zip file is a compressed collection of a set of files/folders. The OS package is used for performing copy operations, the io pacakge is for reading and writing operations whereas the archive/zip package is for unzipping and zipping the file. In this article, we are going to learn about using all these packages to perform the copy and unzipping of the files and printing the same. Method 1: Using io and os package This program uses ...
