What are uses of globle main and exceget answer?

Answer 1

The global keyword in Python is used to declare that a variable inside a function refers to a variable defined at the global scope, allowing for its modification. This is useful when you need to update the value of a global variable within a function rather than creating a new local variable. It helps maintain state across function calls and is often used in scenarios where global configuration or counters are needed. However, its use can lead to code that is harder to understand and maintain, so it should be used judiciously.
