Alternatives to Combo challenge using enumerate

Though I've actually done this task now, it took me a looong time and I thought I'd go through a few other variations. When I started looking for a solution using 'enumerate' I hit a rut though. Can anyone tell me why this isn't working (syntax error at the .format). Many thanks!! 

def combo(a,b):
    tuple_list = []
    b = list(enumerate(b))
    position = 0
    for i in list(enumerate(a)):
        tuple_list += "{}:{}".format.(i,b[position])
        position += 1
        print (tuple_list)

MOD: I formatted your code to make it easier for everyone to read. Thanks for posting! (See the Markdown Cheatsheet below the question textbox to see how to format code. Don't worry, it's easy! :-))

The error is from the extra . you have after format.

tuple_list += "{}:{}".format.(i,b[position])
                            ^
