This small variation might point the way.  If you can explain it, you'll
be most of the way there.

x = "A"
print("x = " + x)

def f(y):
    x = "B"
    print("In f, x = " + x + "  y = "+ y)

f(x)
print("x = " + x)

The material I cut did include the explanation so go back and read the
message you replied to here if you don't follow.
