Example : A Python program to create a new or blank file to store some contents. Example : A Python program to Read the stored contents.

Python offers several ways to create GUI (Graphical User Interface) user-friendly applications. Some of the most popular Python libraries are used for building GUI applications:- Tkinter (Built-in GUI Library) This library is already included with/pre-installed with Python/built into Python (no extra installation is needed). This is simple, easy, and lightweight. Read more…

Introduction File handling in Python allows us to read, write, and manipulate files (text or binary) stored on our system. Python provides several built-in functions to work with files, such as open(), remove(), write(), etc. Definition A file in Python is a storage unit on a computer where data can Read more…

Definition Regular expressions (regex) are a powerful tool in Python that are used for matching desired patterns in strings/text. Features Regular expressions (regex) allow us to search, match, and manipulate strings based on patterns.  We can test our regex patterns using tools like regex101.com. ‘re’ Package/Module Functions  Python provides the ‘re‘ Read more…

Definition In Python, a string is a sequence of characters enclosed within single (‘ ‘), double (” “), or triple quotes (”’ ”’ or “”” “””). Strings are immutable, i.e. they cannot be changed after creation. Strings in Python are powerful and come with many built-in methods for manipulation.  String Read more…

Definition of Function in Python A function is a block of reusable code that performs a specific task.  Functions are essential for writing efficient, modular, and maintainable Python code. They make programs more structured, easier to debug, and reusable, which is crucial for both small scripts and large software projects. Read more…
