No use of variable from for loop with range

Question

This piece of code is from a bigger program and builds a random ascii string

Why is the variable i used? It is not used anywhere else

Thanks

def buildblock(size):
    ascii = ''
    for i in range(0, size):
        a = random.randint(65, 160)
        ascii += chr(a)
    return(ascii)

It is used like:

buildblock(random.randint(3,10))

You can choose any other name for the loop variable, it's just that any variable is needed for the loop. A common convention in cases where that variable name is not used anywhere else is a simple underscore, _.
