Conditionally change a global variable

I would like to do something similar, but I have SyntaxWarning and it does not work as expected

RAWR = "hi"
def test(bool):
    if bool:
        RAWR = "hello"   # make RAWR a new variable, don't reference global in this function
    else:
        global RAWR
        RAWR = "rawr"    # reference global variable in this function
    print RAWR           # if bool, use local, else use global (and modify global)

How do I make this work? Passing in True or False changes the global variable.

class store_RAWR(object):

    def __init__(self, new): self.RAWR = new

def test(newone):
    if newone:
        myR = store_RAWR("hello") # get a (temporary) object with a different string
    else:
        myR = store_RAWR # set the class, which is global.
    # now modify myR.RAWR as you need
