Format SQL Query Output

[phillyfa]

I'm selecting data from a table and returning all records. However, the records are being returned with a blank space separator instead of a comma. Any idea how to return rows like the following:

Output:
1,sales,marketing,04212020

Instead of:

Output:
1 sales marketing 04212020

Here's the function:

def select_from_database(conn, tablename):
    cursor = conn.cursor()
    print("Connected to: %s" % database)

    cursor.execute("SELECT * FROM %s " % tablename)
    rows = cursor.fetchall()
    print("Total records: %s" % len(rows))

    for i in rows:
        print(*i)
        #print("%s %s" % (row[0], row[1]))

    cursor.close()

Thanks!
