实验第一个python程序

1.查看python的版本信息
[wangli@rd-openet-ww wangli]$ python -V     //V要大写
Python 2.5.2      

2.编辑一个小程序
#!usr/bin/python
#filename:hellowrold.py
contact = {}
contact_list = []
while 1:
    contact['name'] = raw_input("please input name: ")
    contact['phone'] = raw_input("please input phone number: ")
    contact_list.append(contact.copy())
    go_on = raw_input("continue?\n")
    if go_on == "yes":
        pass
    elif go_on == "no":
        break
    else:
        print "you didn't say no\n"
i = 1
for contact in contact_list:
    print "%d: name=%s" % (i, contact['name'])
    print "%d: phone=%s" % (i, contact['phone'])
    i = i + 1

3.也可在解析器下运行
>>> import sys
>>> sys.stdout.write("Hello World!\n")
Hello World!
>>>
退出解释器的方法是Ctrl+D或者Ctrl＋Z
