Inner function not printing nonlocal variable

Question

I have one outer function and 2 inner functions.

def outer():
    x = 'hello'    
    def inner1():
        def inner2():
            nonlocal x
            x = 'python'        
        inner2()
        print(x)
outer()

Please help me understand why the above code is not printing the value of x.

As per my understanding, it should print "hello"
