Tuples in Python are a fundamental data type. They are similar to lists but have unique features. These features make them particularly useful for scenarios where data integrity is paramount. They are ideal for storing collections of items that should... Read more
The string is a sequence of characters enclosed in a single (‘ ‘) or double (” “) or triple quotes (”’ ”’ or “”” “””). Creating Strings String Indexing and Slicing Example: Reverse a String: Mathematical Operators for String In... Read more
Type casting is the process of converting a variable or value from one data type to another. This is often necessary to perform operations that require specific data types or to optimize data storage and manipulation. Common Type Casting Functions... Read more
Database connectivity is a crucial aspect of modern software development, enabling seamless interaction between applications and databases. In Python, database connectivity allows developers to perform operations such as storing, retrieving, updating, and deleting data from various database management systems (DBMS).... Read more
Regular expressions (RegEx) are a potent tool for defining search patterns in strings. They allow us to find, validate, and manipulate text by specifying a particular format or structure. Python provides built-in support for regular expressions via the “re” module,... Read more
File handling is a key aspect of Python programming, allowing us to work with files to read, write, and manipulate data stored in them. Python provides built-in functions and methods to perform these operations efficiently. What is the file? A... Read more
Exception handling is a mechanism in Python that deals with runtime errors, allowing the program to continue execution or handle errors gracefully. It is an essential tool for making Python applications robust and error-resistant. Definition An exception is an event... Read more
In Python, abstract classes and interfaces are primarily used to define a blueprint for other classes. They allow you to create a common structure for classes while enforcing specific methods to be implemented in subclasses. For example, if you want... Read more
Indexing: To access the individual elements in a sequential data types like a string, list, or tuple using their index position. In Python, the indexing number starts from 0 for the first element. Two types of indexing: Syntax: sequence[index_number] Example:... Read more
