In Python, we can open a file in a read-write mode without truncating the file by opening the file in a+ mode. Truncating a file refers to deleting the existing content of the file before opening the file. In this article, we will discuss how we can open the file in the read-write mode without truncating the file. What is a+ mode The a+ mode in Python is used to open the file in a read-write mode without truncating the file. When the file is opened in a+ mode it allows us to write new data at the end of ...

In Python, we can open a file in read-write mode by truncating the file by opening the file in w+ mode. Truncating a file refers to deleting the existing content of the file before opening the file. In this article, we will discuss how we can open the file in the read-write mode by truncating the file. What is the w+ mode The w+ mode in Python is used to open the file in read-write mode with file truncation. When the file is opened in w+ mode it allows us to read and write data in the file. If the ... Read More
Enum in Python is a user-defined data type consisting of a set of named values. A finite set values of is defined using enums and these values can be accessed in Python using their names instead of their integer values. Enum makes the code more readable, and more maintainable and also enforces type safety. In this article, we will see how we can look up enums by their string value in Python. To look up an enum by string value we need to follow the following steps: Import enum module in the code Define enum with desired set of ... Read More
In Python, we can insert a string into another string using the string concatenation method, string interpolation method, and using replace() method. Python provides various ways to insert a string into another string. In this article, we will understand all the methods with the help of suitable examples. Method 1: Using the Concatenation Operator String concatenation simply joins two strings together using the (+) operator. Any number of strings can be concatenated using this method in a simple and effective way. Example In the below example, we initialized three strings namely string1, string2, and inserted_string. We need to insert the ... Read More
Introduction AJAX (Asynchronous JavaScript and XML) is a set of web development techniques used to create fast and dynamic web pages. Take a moment to imagine yourself conducting a search on Google. When you enter the correct search criteria, a variety of possibilities are often displayed in the search box. How about their origin? Definitely not from the client's perspective. This allows the user to successfully communicate with the server without having to reload the page. There are numerous examples like this that can all be considered. Ajax, in a nutshell, is what makes everything work. Definition and Explanation of ... Read More
In Python, we can implement switch statements on a string using the dictionary-based approach, class-based approach, and lambda-based approach. Unlike other programming languages like Java, c++, etc python does not have an inbuilt switch statement. In this article, we will see how we can achieve the switch statement functionality in Python using a dictionary-based approach and class-based approach, and lambda-based approach. The Switch Statement in Other Programming Languages Before understanding how Python implements switch statements we need to understand how to switch statements work and how they are implemented in other programming languages. A switch statement is a conditional statement ... Read More
In Python we can use the find() and index() methods to get the index of the first occurrence of the substring in a string. Python provides various string manipulation functions to modify and access text data. In this article, we will write a program to get the index of the substring in a string. Method 1: Using the find() method The find method searches for the specific substring which is passed as a parameter to the function and returns the starting index of the substring. If the substring is not found in the string then the find() method returns -1. ... Read More
In Python, we can use various methods like using square brackets, slicing, and using indices to get characters from the string with the help of their index. A string is a sequence of characters with each character being assigned a unique index. The index specifies the position of the character in the string. The index of the first character starts with 0 and the index of the last character in the string is the length of the string minus one. We can use the index value of the character to access a particular character in the string. Accessing Characters From ... Read More
In Python we can get a character from the given string using the indexing operator ‘[ ]’, using slices, and using indices separated by a colon. By passing the index of the character we want to access to the index operator we can easily get the character from the string. In this article, we will see how we can access the character of the string using the index operator. Using [ ] Operator Syntax string[index] Here string is the given string from which we want to access a specific character. The index is the index of the character in ... Read More
