How does global scope work in Python?

Can you explain how global scope works in Python?

Sure! In Python, global scope refers to variables that are defined outside of any function. These variables can be accessed from anywhere in the code.

What happens if I try to modify a global variable inside a function?

If you want to modify a global variable inside a function, you need to use the global keyword. Otherwise, Python will treat it as a local variable.

Can you give me an example of using global variables?

Of course! Here's a simple example:

x = 10  # global variable

def my_function():
    global x
    x += 5  # modifies the global variable

my_function()
print(x)  # Output will be 15
