Python中文显示问题&数据库连接传参

1.Python连接mysql数据库，并且传递参数

con = MySQLdb.connect(host='***', user='root', passwd='***', db='***', port=***, charset='utf8')
cur1 = con.cursor()
cur2 = con.cursor()
cur1.execute("SELECT distinct(a6) FROM b where a2=%s ", (Id[0]))
cur2.execute("SELECT distinct(a6) FROM b where a2=%s ", (Id[1]))

program1 = set()
program2 = set()
for eachprogram1 in cur1:
    program1.add(eachprogram1)
for eachprogram2 in cur2:
    program2.add(eachprogram2)

cur1.close()
cur2.close()
con.close()

2.Python2存在中文打印时候的显示问题，在网上找了半天都没有解决，原来就只是需要，逐个元素的打印，不能打印list或者tuple

for each in jiao:
    print each[0]
