关于python2.7从数据库读取中文显示乱码的问题解决
#!/usr/bin/env python # _*_ coding:utf-8 _*_ import MySQLdb import sys str = raw_input("please input error code:") conn = MySQLdb.connect(host='127.0.0.1', user='root', passwd='123456', db='error_code',charset='utf8') cur = conn.cursor() sql ="select * from error_message where code = " + "'" + str + "'" cur.execute(sql) data=cur.fetchall() print "分类:"+data[0][0].encode("UTF-8"),"错误码:"+data[0][1].encode("UTF-8"),"错误描述:"+data[0][2].encode("UTF-8"),"相关业务方:"+data[0][3].encode("UTF-8") cur.close() conn.close()
主要有两点如下:
1、在连接数据库时要指定编码类型,如果不指定,将会报如下错误,就算第二步编码了也会出问题。
charset='utf8'
2、在输出数据的时候需要编码:data[0][0].encode("UTF-8"),如果不编码则会报错:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 0: ordinal not in range(128)
