Updating muliple SQLite rows given columns and data

I'd like to be able to update multiple SQLite database rows given a list of columns and a list of lists of data. I have a working solution, but it's not elegant at all. How can I do this more efficiently. I've left out the actual UPDATE statement as I am just focusing on building the query.

def update(columns, values):
    for value in values:
        print ("Update myTable SET " + " ".join([x + ' = "%s",' for x in columns]) + ' WHERE SSN = "%s"').replace(", WHERE", " WHERE") % (tuple(value))

columns = ['Name', 'Age']
values  = [['Jon', 12, '545-45-7987'], ['Sam', 13, '454-78-4545']]

update(columns, values)
