The purpose of internal buffers, which are created by the runtime, library, and programming language that you're using, is to speed up operations by preventing system calls on every write. Instead, when writing to a file object, you write into its buffer, and when the buffer is full, system functions are used to write the data to the actual file. Syntax Following is the syntax of flush() function − File_name.flush() No parameters are accepted by it. This method returns nothing; its return type is . Example -1 The flush() method in the program below simply clears the file's internal ... Read More
The file truncate() method is quite effective. The first reason it is referred to as a method rather than a function is that it comprises the file name (i.e., the object of the file) and a dot operator in addition to other factors (i.e. object of file). Truncation means cutting off. In this case, we define cutting-off in terms of size. Syntax Following is the syntax used to truncate the file to a given size − file.truncate(size) Sending the parameter to this method is not essential. If the size is given as a parameter, it must be given ... Read More
There are various ways to read files in Python. The most common methods for reading files line by line in Python will be covered. Using readlines() Method Using this method, a file will be opened and its contents will be divided into separate lines. A list of every line in the file is also returned by this method. To effectively read a whole file, we can use the readlines() function. Following is an example to remove swap files using file.endswith() method − Example Following is an example to read a text file line by line using readlines() method − # ... Read More
This tutorial looks at various Python comparison techniques for two files. We'll go over how to perform this typical work by using the available modules, reading two files, and comparing them line by line. In Python, comparing two files can be done in a variety of ways. Comparing Two Text Files Line by Line Using the open() function to read the data from two text files, we can compare the information they contain. The local directory will be searched for and potentially read by the open() function. Example We'll contrast two files containing python data in this example. We're informed ... Read More
Open(), a built-in function in Python, opens a file and returns a file object. Methods and properties in file objects can be used to gather data about the file you opened. They may also be used to modify the mentioned file. Open a file Two arguments are required for this function. The filename and full path are listed first, followed by access mode. A file object is returned by this function. syntax Following is the syntax used to open a file: open(filename, mode) Here, the filename and it's path are specified by a string argument, and the mode argument ...

Hyper Text Markup Language which is also known as HTML is used to create web pages and web applications. This application made using HTML are accessible to anyone on the world wide web (internet). The Hydertext and Markup language together help define a basic blueprint of the website or web applications.An HTML tag is used to indicate the beginning and closing for an HTML element of an HTML document. With help to these HTML tags a browser transforms an HTML document into a website or web application. In general, a tag is structured with three components, Opening Tag - Marks ... Read More
The HTML element defines the document's title that is shown in a browser's title bar or a page's tab. It gives a brief and exact description of the documents content. It is also the default name used if the user wishes to bookmarks the web page. Syntax Page title content The HTML plays an important role in on-page search engine optimization, it helps the search engine users decide to click to your site rather than another. Badly-formatted title tags can harm your search rankings and make your links less appealing even though it appears on ... Read More
A computer's file system's directory is an organisational feature used to store and locate files. A tree of directories is created by organising directories hierarchically. There are parent-child relationships in directories. A folder can also be used to refer to a directory. Python has accumulated a number of APIs that can list the directory contents over time. Useful functions include Path.iterdir, os.scandir, os.walk, Path.rglob, and os.listdir. We could need a list of files or folders in a given directory in Python. You can accomplish this in a number of ways. OS module A function that returns a list of the ... Read More
In this tutorial, we will learn to convert the MySQL date to JavaScript date. The MySQL date is not different from the regular date, but its format or syntax is different, which we need to convert into the format of a normal date. The general syntax of the MySQL date is YYYY - MM - DD HH: mm: ss. So, we need to convert the given MySQL date string syntax to normal date syntax. We will have two approaches to converting the MySQL date to the JavaScript date. Using the replace() Method Using the split() Method Using the ... Read More
In this tutorial, we will learn to convert seconds to Hours, Minutes, and Seconds (HHMM-SS) format in vanilla JavaScript. The date and time are an integral aspect of our daily lives; date and time are frequently used in computer programming. You might need to write a website in JavaScript with a calendar, a rail schedule, or an interface for scheduling appointments. So, for such purposes, JavaScript provides us with some inbuilt functions like the getTime() returns the number of milliseconds since January 1, 1970, 00:00:00. Using the toISOString() Method We might need to put seconds into a well-formatted structure to ... Read More
