String replacement not working

I'm a bit embarrassed to ask:

but why won't this successfully work? the .statswith method is fine here, returning True, but i can't get this replace to work...

sandwich = "Au Cheval Cheeseburger"
restaurant = "Au Cheval"
if sandwich.startswith(restaurant):
    sandwich.replace(restaurant, "")
print sandwich

(if you can't tell, i want sandwich to just read Cheeseburger. Is there also a more efficient way to do this than going thru string replace?

thanks everyone.

EDIT: God i knew it was something silly. It's late and the brain's fried. thanks everyone.

You were doing fine but till the replace method

The replace methods just replaces and provides the string it does not store it in the variable

Since you did not not store it the variable is not changed

sandwich = "Au Cheval Cheeseburger"
restaurant = "Au Cheval"
if sandwich.startswith(restaurant):
    sandwich=sandwich.replace(restaurant, "")
print sandwich

previously you did not save it

sandwich.replace(restaurant, "")

But to save the replacement changes you have to save it

sandwich=sandwich.replace(restaurant, "")

string replacement returns a copy.

sandwich = sandwich.replace(restaurant, "")

From http://www.tutorialspoint.com/python/string_replace.htm

The method replace() returns a copy of the string in which the occurrences of old have been replaced with new

Try sandwich = sandwich.replace(restaurant, "")
