演示了Python中的字符串通过split分割后的使用和把分割后的字符串连接起来

shell> vi 2.py

#!/usr/bin/env python

str = ("i am a worker, and you are a student !")

print str

#split the str,if not specified the separator ,the whitespace is a separator,items is a sequence

items = str.split()

print items

#join the str

sep=":"

items=sep.join(items)

print items

执行这个脚本2.py，得到的结果为:
i am a worker, and you are a student !
['i', 'am', 'a', 'worker,', 'and', 'you', 'are', 'a', 'student', '!']
i:am:a:worker,:and:you:are:a:student:!
