MySQL adapter question

[Pop Tufty]

OK,  I searched the python.faqts for this seemingly simple
issue and came up empty:

I got the data from the database, thank you, and I want to
graph it, so I think -- That's easy, use string.atoi(row[i])
to get what I want - no dice.  When I use the atoi above, I get

TypeError: argument 1: expected string, int found

When I try to pass row[i] directly  to my function (see below) to
map an integer to a y value, it looks like it thinks it is a string...

this_y   =   percent_to_y(row{i])

TypeError: bad operand type(s) for /

def percent_to_y(percent):
    retval = bot - ygap - ((percent * ygap) / 10)
    return retval

What is going on?
