What is the scope of variables in programming?

The scope of a variable refers to the context within which it is defined and accessible. There are generally two types: local and global.

Can you explain local and global scope with examples?

Sure! A local variable is defined within a function and can only be accessed there. For example, in Python:

def my_function():
    local_var = 5  # This is a local variable
    print(local_var)

A global variable is defined outside any function and can be accessed anywhere in the code:

global_var = 10  # This is a global variable

def another_function():
    print(global_var)

What happens if I try to access a local variable outside its function?

If you try to access a local variable outside its function, you'll get a NameError in Python, indicating that the variable is not defined.
