?What are the main data types supported by variables in Python, and how do they differ

Python supports various data types, including integers, floats, strings, lists, tuples, dictionaries, and sets. Integers represent whole numbers, floats represent decimal numbers, strings represent text data, lists are ordered collections of items, tuples are immutable sequences, dictionaries are key-value pairs, and sets are unordered collections of unique elements. Understanding these data types is essential for effective variable usage and manipulation in Python.

?How does variable scope impact the accessibility and lifespan of variables in Python

Variable scope refers to the region of code where a variable is accessible. In Python, variables can have global or local scope. Global variables are accessible throughout the entire program, whereas local variables are confined to the block of code where they are defined. Understanding variable scope is crucial for avoiding naming conflicts and managing memory efficiently. Additionally, variables' lifespan differs based on scope: global variables persist until the program terminates, while local variables are destroyed once their containing function exits.
