Multiline Strings Multiline strings in Python are strings that span multiple lines. They are useful for representing large blocks of text, such as documentation, long strings, or text that includes line breaks. Python provides several ways to handle multiline strings, each with its own use cases. Using Triple Quotes Multiline strings are typically created using […]

Introduction to Strings in Python Strings in Python are one of the fundamental data types used to represent and manipulate text. They are immutable, meaning that once a string is created, it cannot be modified. Instead, new strings are created for any modifications. Defining Strings Strings can be defined using single quotes (‘), double quotes

Course on Python Casting Introduction to Casting in Python In Python, casting refers to converting a variable from one data type to another. Python is a dynamically-typed language, meaning the type of variables is determined automatically. However, it may be necessary to explicitly convert types for specific operations or to ensure type compatibility. Common Data

Floating-Point Numbers (float) in Python Floating-point numbers (float) in Python represent real numbers and include a decimal point. They are used for calculations that require fractional values and are more flexible than integers for representing numbers with decimals. Characteristics of Floating-Point Numbers Memory Representation In Python, floating-point numbers are represented using the IEEE 754 standard
