    def db(self, item):
        b = 0;
        a = 0;
        table_name = len(item['Category_label'])
        total_name = len(item['Names'])
        while b <= table_name:
            while a <= total_name:
                self.cursor.execute("insert into %s ( NameTeam, Score, Data) values (%s,%s,%s); ",
                                    (item['Category_label'][b],
                                        item['Names'][a],
                                        item['Score'][a],
                                        item['Date'][a]
                                    ))
                self.connect.commit()
                a += 1;
            b += 1;

Answer 1

The table name cannot be substituted.

Answer 2

self.cursor.execute(
    "insert into %s ( NameTeam, Score, Data) values (%%s,%%s,%%s); " % item['Category_label'][b],
    (item['Names'][a], item['Score'][a], item['Date'][a])
)

so in theory it should work
