Nonlocal Variables in Python: Working with Enclosed Scopes

So, now we understand the difference between global and local variables and have learned about nested functions. The nonlocal variable is used in nested functions. Let's look at an example:


              
123456789101112

            
def outer_function():
    outer_var = 10 

    def inner_function():
        nonlocal outer_var
        outer_var += 5
        print("Nonlocal variable in inner function:", outer_var)

    inner_function()
    print("Nonlocal variable in outer function:", outer_var)

outer_function()
copy

Just as with global variables, we cannot change the variable created in outer_function inside inner_function without using the special keyword nonlocal.

The output is:

python

Var allt tydligt?

Hur kan vi förbättra det?
