In this article, we will learn what should never do when working with Python. Use Class Variables Carefully In Python, class variables are used as dictionaries and are referred to as Method Resolution Order (MRO). Furthermore, if a class lacks one attribute, then that class lacks a property. That is, if you modify what is in a class, other classes should not change as well. Improper Indentation In Python, indentation is everything. Python utilizes indentation online, unlike Java, C++, and other programming languages, which use curly brackets to construct code blocks. Many properties are affected by indentation. Some Python indentation ... Read More
In this article, we will learn the uses of the map function in Python. What is a map() Function? Python's map() function applies a function to each item in an iterator that is provided as input. A list, tuple, set, dictionary or string can all be used as iterators, and they all return iterable map objects. Map() is a built-in Python function. Syntax map(function, iterator1, iterator2 ...iteratorN) Parameters function − It is necessary to provide a map with a function that will be applied to all of the iterator's available items. iterator − a mandatory iterable object. It ... Read More
In this article, we will learn about the // operator in Python in detail. To do floor division in Python, use the double slash // operator. This // operator divides the first number by the second number and rounds the result to the closest integer (or whole number). Syntax of // Operator To utilize the double slash // operator, follow the same steps as in regular division. The only difference is that you use a double slash // instead of a single slash / − Syntax first_number// second_number Floor Division Algorithm (Steps) Following are the Algorithm/steps to be followed ...

In this article, we will learn the Is the Python platform independent or Not in detail Python Python is a high-level, object-oriented, dynamic, multipurpose, platform-independent programming language i.e multi-paradigm language. It is used in areas such as data analytics, robotics, and artificial intelligence, machine learning. Python supports several programming paradigms, including Object Oriented Programming, Structured programming, and certain functional programming features. Python also supports contract programming and logic programming, but only with the help of extensions. This language's syntax is not difficult and is relatively simple when compared to other languages such as C, Pascal, and others. As a result, ... Read More
In this article, we will learn In terms of ease of learning for new programmers, how does Python compare to PHP? Comparison of Uses and Easiness: Python vs PHP Python Python is a programming language that can be used for a variety of purposes hence it is a general-purpose programming language. Artificial intelligence, machine learning, web development, data analytics, game development, and financial predictive models are just a few of the applications. Python is used by almost all current technology organizations, including Google and Netflix. Python is a popular programming language among data scientists for data cleaning, visualizing, and creating ... Read More
In this article, we will learn to code a vending machine in Python. Vending Machine with Python Each item will have its product id, product name, and product cost properties stored in a dictionary. a list that is currently empty but will later be filled with all the selected items. The value of a "run" variable is True up until the point at which the user decides they are satisfied and do not wish to buy any more products; at that point, the value is changed to False, and the loop ends. We will now try to understand the Python ... Read More
In this article, we will show how to sort a list of dictionaries by the values of the dictionary in Python. Sorting has always been a useful technique in everyday programming. Python's dictionary is often used in a wide range of applications, from competitive to developer-oriented (example-handling JSON data). It can be useful in certain situations to be able to filter dictionaries based on their values. Below are the 2 methods to accomplish this task − Using sorted() and itemgetter Using sorted() and lambda functions What is a Dictionary? Dictionaries are Python's version of an associative array data ... Read More
In this article, we will learn what is a .data file and how to read a .data file in python. What is a .data file? .data files were created to store information/data. Data in this format is frequently placed in either a comma-separated value format or a tab-separated value format. In addition to that, the file may be in binary or text file format. In that case, we'll have to find another way to access it. For this tutorial, we will be working with.csv files, but first, we must determine whether the file's content is text or binary. Identifying data ... Read More
In this article, we will discuss whether or not we can get a job with a Python certificate, as well as what types of jobs we can acquire after getting the Python certificate. What is Python? Python is a high-level, object-oriented, dynamic, interpreted, and multipurpose programming language i.e multi-paradigm language. Python's syntax, dynamic typing, and interpreted nature make it an excellent scripting language. It supports a variety of programming paradigms, including object-oriented, functional, and procedural styles. Additionally, because it is an, it cannot be converted to computer-readable code before running at runtime. Python is used for task automation. Use of ... Read More
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find mean and median of an unsorted array in Java. Mean of an array can be derived by calculating the average value of all the elements present inside the array. Mean= (sum of all elements present in array) / (total number of elements present) Median of an array represents the middle element present in an odd number sorted array and if the sorted array consists of even number, then median can be ...
