What is the difference between local and global scope in programming?

What is the difference between local and global scope in programming?

Local scope refers to variables defined within a function, while global scope refers to variables defined outside any function.

Can you give me an example of each?

Sure! In Python, a variable defined inside a function is local, like def my_func(): x = 10. A global variable would be defined outside, like y = 20.

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

You will get a NameError because the local variable is not accessible outside its function.

Are there any exceptions to this rule?

Yes, if you use the global keyword inside a function, you can modify a global variable.
