Solution: Scope

Create a global variable m = "test"

m = "test"

create a function that

1. has a local variable m having a value of "yes"
2. return m

def func():
    m = 'yes'
    return m     

Run that function and save the return to a variable n.

n = func()

print out m an n

print(m,n)

test yes

create a function that

1. changes the global variable m to "yes"
2. return m

def func2():
    global m
    m = 'yes'
    return m

Run the new function and save the result to a variable w.

w = func2()

print out m and w

print(m,w)

yes yes
