Why does my PyMySQL program give me 1064 error, if everything seems correct?

Question

Here's my code:

def delete_people(tname, del_name):
    try:
        with connection.cursor() as cursor:

            del_ppl = 'DELETE FROM project3.%s WHERE id = %d; ALTER TABLE project3.%s DROP id; ' \
                      'ALTER TABLE project3.%s ADD id int UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY FIRST; ' \
                      'ALTER TABLE project3.%s AUTO_INCREMENT = 1;'
            cursor.execute(del_ppl % (tname, del_name, tname, tname, tname, ))
            connection.commit()
            print('dltd sucsefuly')


    except Exception as ex:
        print("Connection refused...")
        print(ex)

And when i try to launch this function, i always got this mistake:
(1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ALTER TABLE project3.xcpsdojn DROP id; ALTER TABLE project3.xcpsdojn ADD id int ' at line 1")

I can't understand where's the mistake, because this exact code works in MySQL just fine. I'll appreciate your help!
