Failed to insert record into MySQL table.Python type tuple cannot be converted

[farah97]

I want to create sentiment analysis using Vader in Python and Mysql. The problem is, I got the error on mysql, especially when to insert the data into the database. The error that I got is

Error:
Failed to insert record into MySQL table Failed executing the operation; Python type tuple cannot be converted

Here are the code:

 sql_select_Query = "select a from table1 union select b from table1"
    cursor = connection.cursor()
    cursor.execute(sql_select_Query)
    records = cursor.fetchall()


    for row in records:
        print(row)

        sid_obj = SentimentIntensityAnalyzer() 

        sentiment_dict = sid_obj.polarity_scores(row) 

        if sentiment_dict['compound'] >= 0.05 : 
            sentiment = 'positive'

        elif sentiment_dict['compound'] <= - 0.05 : 
            sentiment = 'negative'

        else : 
            sentiment = 'neutral'

        mySql_insert_query = """INSERT INTO sent (q,polarity,senti) VALUES (%s,%s,%s) """

        records_to_insert = [(row,sentiment_dict['compound'], sentiment)]

        cursor = connection.cursor()
        cursor.executemany(mySql_insert_query, records_to_insert)
        connection.commit()
        print(cursor.rowcount, "Record inserted successfully into table")

except mysql.connector.Error as error:
    print("Failed to insert record into MySQL table {}".format(error))


except Error as e:
    print("Error while connecting to MySQL", e)
finally:
    if  (connection.is_connected()):
        cursor.close()
        connection.close()
