append(), extend(), and insert() methods in Python lists, along with slicing where applicable. 1. append() Method Adds a single element to the end of the list. Examples: 2. extend() Method Adds multiple elements (iterable items) to the end of the list. Examples: 3. insert() Method Inserts an element at a specific position. Examples: Key Differences: Method Modifies List? Adds Single/Multiple Elements? Position append() ✅ Yes Single element (even if it’s a list) End…

The Fractions module in Python is a built-in module that provides support for rational number arithmetic. It allows you to work with fractions (like 1/2, 3/4, etc.) exactly, without the precision issues that can occur with floating-point numbers. What Problems Does It Solve? Problem with Floating-Point Numbers: python # Floating-point precision issue print(0.1 + 0.2) # Output:…

Python re Flags: re.I, re.S, re.X Explained Flags modify how regular expressions work. They’re used as optional parameters in re functions like re.search(), re.findall(), etc. 1. re.I or re.IGNORECASE Purpose: Makes the pattern matching case-insensitive Without re.I (Case-sensitive): python import re text = “Hello WORLD hello World” # Case-sensitive search matches = re.findall(r’hello’, text) print(“Case-sensitive:”, matches) # Output: [‘hello’] # Only finds lowercase…

Python does not support traditional method overloading in the way languages like C++ or Java do. If you define multiple methods with the same name, the last definition will simply overwrite all previous ones. However, you can achieve the same result—making a single method behave differently based on the number or type of arguments—using Python’s…
