Python复习

1.python的斐波那契数:

1 def fab(max):
2     n,a,b=0,0,1
3     while n<max:
4         print b
5         a,b=b,a+b
6         n=n+1
7 
8 fab(4)
fab

2.python求偶数(奇数可以推出,注意缩进)

1 def test(n):
2     var=0
3     L=[]
4     for var in range(n):
5         if (var%2==0):
6                 print var
7 test(7)

3.python对数据库的操作(注意要导入,库MySQLdb)下载地址http://sourceforge.net/projects/mysql-python/

 1 #coding=utf-8
 2 import MySQLdb
 3 
 4 conn= MySQLdb.connect(
 5         host='127.0.0.1',
 6         port = 3306,
 7         user='root',
 8         passwd='miao',
 9         db ='testweb',
10         )
11 cur = conn.cursor()
12 
13 #创建数据表
14 #cur.execute("create table student(id int ,name varchar(20),class varchar(30),age varchar(10))")
15 
16 #插入一条数据
17 cur.execute("insert into student values('2','Tom','3 year 2 class','9')")
18 
19 
20 #修改查询条件的数据
21 #cur.execute("update student set class='3 year 1 class' where name = 'Tom'")
22 
23 #删除查询条件的数据
24 #cur.execute("delete from student where age='9'")
25 
26 cur.close()
27 conn.commit()
28 conn.close()
