python数据分析用什么数据库

import sqlite3
with sqlite3.connect(":memory:") as con:
 c=con.cursor() #创建游标
 c.execute('''CREATE TABLE sensors(data text,city text,code text,sensor_id real,temperature real)''') #新建表，text和real分别表示字符串和数值的类型
 for table in c.execute("SELECT name FROM sqlite_master WHERE type='table'"):
 print "Table",table[0]
 c.execute("INSERT INTO sensors VALUES ('2016-11-05','Utrecht','Red',42,15.14)")
 c.execute("SELECT * FROM sensors")
 print c.fetchone() #

Table sensors
(u'2016-11-05', u'Utrecht', u'Red', 42.0, 15.14)
