How to Merge Elements in a Python Sequence?
Python Sequences includes Strings, Lists, Tuples, etc. We can merge elements of a Python sequence using different ways. Merge Elements in a Python List Example The join() method is used to merge elements − # List myList = ['H', 'O', 'W', 'A', 'R', 'E', 'Y', 'O', 'U'] # Display the List print ("List = " + str(myList)) # Merge items using join() myList[0 : 3] = [''.join(myList[0 : 3])] # Displaying the Result print ("Result = " + str(myList)) Output List = ['H', 'O', 'W', 'A', 'R', 'E', 'Y', 'O', 'U'] Result = ['HOW', 'A', 'R', ...
Read MoreWhat Does the // Operator Do?
In Python, the // is the double slash operator i.e. Floor Divison. The // operator is used to perform division that rounds the result down to the nearest integer. The usage of the // operator is quite easy. We will also compare the results with single slash division. Let us first see the syntax: Syntax of // (double slash) Operator The a and b are 1st and 2nd number: a // b Example of // (double slash) Operator Let us now see an example to implement the double slash operator in Python - a = 37 b = 11 ...
Read MoreHow to include JavaScript in HTML Documents?
In this tutorial, we will learn how to include JavaScript in HTML Documents. To include JavaScript in HTML Documents, use the tag. JavaScript can be implemented using JavaScript statements that are placed within the ... . You can place the tags, containing your JavaScript, anywhere within your web page, but it is normally recommended that you should keep it within the tags. We will discuss the following three approaches to include JavaScript in HTML documents − Embedding code (within head or body) Inline Code (inside any element) External file (outside the HTML file) By Embedding ...
Read MoreNumpy Array advantage over a Nested List
In this article, we will learn about the advantages of a Numpy array with a Nested List in Python. The Numpy array definitely has advantages over a Nested. Let’s see the reasons − The array in Numpy executes faster than a Nested List. A Nested List consumes more memory than a Nested List. Numpy Array NumPy is an N-dimensional array type called ndarray. It describes the collection of items of the same type. Items in the collection can be accessed using a zero-based index. Every item in an ndarray takes the same size of block in the memory. ...
Read MoreHow to handle tabs, line breaks and whitespace in a text in JavaScript?
In this tutorial, we will learn how to handle tabs, line breaks, and whitespace in a text in JavaScript. To handle tabs, line breaks, and whitespace in text in JavaScript, we can use the whiteSpace property. This property has seven attributes − normal nowrap pre pre-line pre-wrap initial inherit Generally, in HTML we use the entity for multiple spaces and the tag to get line break. But in JavaScript, we use different attribute properties (mainly the normal and pre) of white-space properties to handle the tabs, line breaks, and multiple whitespaces. The details of these two ...
Read MoreHow to play a multimedia file using JavaScript?
In this tutorial, we will learn how to play a multimedia file using JavaScript. The multimedia file is the audio and video files. The multimedia files can be of different formats. wav and mp3 are two examples of audio file formats, whereas mp4 and mkv are examples of video file formats. In HTML, multimedia files can be shown easily using different tags. We use the video tag for showing a video, and for audio, we use the audio tag. These two tags are quite similar, and many attributes are the same in both tags. The "src" attribute defines the path ...
Read MoreHow to pass JavaScript Variables with AJAX calls?
In this tutorial, we will learn how to pass JavaScript Variables with AJAX calls. AJAX stands for Asynchronous JavaScript and XML. As the name suggests, it performs asynchronous operations on your web page. AJAX communicates with the server by HTTP requests and gets the required data as an HTTP response. We can control these HTTP requests by passing the JavaScript variables with AJAX calls. There are various types of HTTP requests, and in this tutorial, we will discuss the most popular HTTP requests by using AJAX and also pass JavaScript variables with it. Pass JavaScript Variables with “GET” AJAX calls ...
Read MoreHow to get the number of seconds between two Dates in JavaScript?
In this tutorial, we will learn how to get the number of seconds between two dates with JavaScript. There are different methods for checking the number of days, hours, and seconds that are commonly used to provide information related to data. Since you can’t manually change the count of the years and months, we follow some simple tricks to get the number in JavaScript. Using the Date getTime() Method In JavaScript, we use different methods to calculate the days, hours, and seconds. Most popular way to calculate the time is .getTime(). However, you will get the result in milliseconds and ...
Read MoreWhat is PEP8?
In this article, we will explain PEP8 and its uses in python. Also, we will see its advantages while coding. What is PEP8? PEP is an abbreviation for Python Enterprise Proposal. Writing code with good logic is a crucial aspect of programming, but many other important elements can affect the quality of the code. The developer's coding style makes the code more reliable, and every developer should remember that Python rigidly follows the string's order and format. A good coding style makes the code more readable. The code is simplified for the end user PEP 8 is a document that ...
Read MoreHow do map, reduce and filter functions work in Python?
In this article, we will show you the Python's map(), filter(), and reduce() functions add a touch of functional programming to the language. All three of these are convenience functions that can be replaced with List Comprehensions or loops but offer a more elegant and concise solution to some problems. map(), filter(), and reduce() all work in the same way. These functions accept a function and a sequence of elements and return the result of applying the received function to each element in the sequence. map() function Like reduce(), the map() function allows you to iterate over each item in ...
