String Alignment and Padding in Python In Python, you can align and pad strings to make them visually consistent in output. The main methods used for this are: 1. str.ljust(width, fillchar) Left-aligns the string and fills remaining space with a specified character (default: space). Syntax: python string.ljust(width, fillchar=’ ‘) Example: python text = “Python” print(text.ljust(10)) #…
Classes and Objects in Python What are Classes and Objects? In Python, classes and objects are fundamental concepts of object-oriented programming (OOP). Real-world Analogy Think of a class as a “cookie cutter” and objects as the “cookies” made from it. The cookie cutter defines the shape, and each cookie is an instance of that shape. 1. Using type() function The type() function returns…
String Indexing and Slicing in Python In Python, strings are sequences of characters that can be accessed using indexing and slicing operations. Here’s a comprehensive explanation with examples: Indexing Strings in Python are zero-indexed, meaning the first character has index 0. python text = “Python” Index positions: text P y t h o n 0…
Strings in Python and Indexing Strings in Python are sequences of characters enclosed in single quotes (‘ ‘), double quotes (” “), or triple quotes (”’ ”’ or “”” “””). They are immutable sequences of Unicode code points used to represent text. String Characteristics Creating Strings python single_quoted = ‘Hello’ double_quoted = “World” triple_quoted = ”’This is…
