How do I use variables as attribute names when using python mysql connector

Question

I am trying to use variables in a python function to try and retrieve attributes with mysql connector

It seems to work only when I specify the name of the attribute in the query itself

def insert(ids, added_attribute):
    insert = ''
    if len(ids) > 0:
        #insert scpecified attributes wanted
        insert += ' AND (%s = %s' %(added_attribute, ids[0])
        #for loop for more than one specified specific attribute
        for id_index in range(1, len(ids)):
            insert += ' OR %s = %s' %(added_attribute, ids[id_index])
        insert += ')'#close parenthesis on query insert
    return insert

def get(name, attributes = 0, ids = []):
    cursor = conn.cursor()

    #insert specific ids
    insert = insert(ids, "id")

    query = 'SELECT %s FROM (TABLE) WHERE (name = %s%s)'

    cursor.execute(query, (attributes, name, insert))

    data = cursor.fetchall()
    cursor.close()
    return data

I keep getting null as a return value

Try this...

query = 'SELECT {} FROM (TABLE) WHERE (name = {}{})'
cursor.execute(query.format(attributes, name, insert))

{} is replacing %s here and to call the variables you just need to add .format() with the vars you want inserted in order.
