可能是这样的吗？

#!/usr/bin/python

import sqlite3

conn = sqlite3.connect('yourdb')

cur = conn.cursor()
cur.execute('''SELECT emotion,
     COUNT(emotion) AS value_occurrence 
     FROM   chatlog
     GROUP BY emotion
     ORDER BY value_occurrence DESC
     LIMIT    1''')

rows = cur.fetchall()

    for row in rows:
        x = row[0]
        y = row[1]
        print(x,y)

从sql打印最常见的值
