with open('users.csv', 'r') as f:
    reader = csv.reader(f, delimiter =',')
    line_count = 0
    next(reader) # Skip the header row.

    for row in reader:
    print (row)
    cur.execute( "INSERT INTO test (name,dates,class_type) VALUES (%s,%s,%s)",row   )

for row in reader:

This give you a list in row attribute, to access the elements you will have to access via index for eg row[0], row[1]. . .

I've added the following code for your reference::

sql = "INSERT INTO customers (name, dates, class_type) VALUES (%s, %s, %s)"
val = (row[0], row[1], row[2])
cur.execute(sql, val)
