What are some examples of variable scope in Python 3.10?

In Python 3.10, variable scope refers to the region of the code where a variable is accessible. For example, variables defined inside a function are local to that function.

Can you give me an example of a local variable?

Sure! Here's a simple example:

def my_function():
    local_var = 10  # This is a local variable
    print(local_var)

my_function()  # This will print 10
print(local_var)  # This will raise an error because local_var is not accessible here.

What about global variables?

Global variables are defined outside of any function and can be accessed anywhere in the code. Here's an example:

global_var = 20  # This is a global variable

def another_function():
    print(global_var)  # This will print 20

another_function()

Are there any differences in variable scope in Python 3.10 compared to earlier versions?

The core concepts of variable scope remain the same in Python 3.10 as in earlier versions. However, Python 3.10 introduced some new features like structural pattern matching, which can affect how you manage variable scope in more complex scenarios.
