  Key Features and Characteristics DynamicTyping In Python, variable types are determined at runtime, not in advance (like in statically typed languages such as C or Java). You don’t need to declare the type of a variable before using it. Simplicity and Readability The simplicity and readability of Python's syntax make it an excellent choice for beginners Extensive Standard Library Python's extensive standard library provides a wide range of modules and functions
