A dictionary in python is a collection of data stored in the form of key value pair. We can assign different datatypes as the value for a key. It helps the coder to store data and categories genres and build databases accordingly. List on the other hand also stores data but here elements are not associated with multiple values. Both dictionaries and lists are indexed. In list we store data in the form of sequences and these sequences can be traversed and manipulated. In this article we will merge the two formats together and create a dictionary of ... Read More

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 ...

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

Let us now dive into what a custom object in python is. We know that python provides us with a lot of pre-defined datatypes which can be used to store various types of data. But there are times where we have to define custom datatypes that can store data that cannot be represented by built-in datatypes. For this purpose, python provides us “classes”, these classes help us customize and create that is fit for our needs. A class can have data and function to implement some behavior. An example of implementing a class in python is as follows − class ... Read More

In this article, you will find out how to use Python to find the first and last elements of a tuple in this tutorial. The quick response is that you can access the first and last elements of the tuple in Python using the index operator([]). The methods described here can be used to obtain your single tuple element. Before diving in to the solution let us understand tuple in python. What is tuple in Python? A tuple is one of Python's four built-in data types for storing data collections. The other three are list, set, and dictionary, each ... Read More

A dictionary in python is a data structure which stores a collection of key value pairs. Unlike other data structures a dictionary contains 2 value at a particular place. A dictionary is a collection which is ordered, mutable and does not allow duplicate elements. A dictionary can be created by placing a sequence of elements within curly { } brackets , separated by ‘comma’ ( , ) . Dictionary holds pairs of values, one being the key and the other corresponding pair element being its value. Values in a dictionary can be of any data type and ... Read More
