You are only required to add comments inline to indicate scope, no output or docstring is required.

def f( y ):

    print( 'f() local vars:', vars() )

  print()

    return x + y

def g( y ):

    global x

    x = 10

    print( 'g() local vars:', vars() )

    print()

    return x*y

def h( y ):

    x = 5

    print( 'h() local vars:', vars() )

    print()

    return y – 1

x = 5

res = f(2) + g(3) + h(4)

print( 'res = {0}'.format( res ) )

Explanation / Answer

def f( y ): //Here y has Local Scope

    print( 'f() local vars:', vars() )

  print()

    return x + y // x is global

def g( y ):

    global x

    x = 10 //x is global

    print( 'g() local vars:', vars() )

    print()

    return x*y

def h( y ):

    x = 5 //x is global

    print( 'h() local vars:', vars() )

    print()

    return y – 1 //y is global

x = 5

res = f(2) + g(3) + h(4)

print( 'res = {0}'.format( res ) )
