复制代码 代码如下:

mulLine = """Hello!!!
Wellcome to Python's world!
There are a lot of eresting things!
Enjoy yourself. Thank you!"""
pr ''.join(mulLine.splitlines)
pr '------------'
pr ''.join(mulLine.splitlines(True))


输出结果:
Hello!!! Wellcome to Python's world! There are a lot of eresting things! Enjoy yourself. Thank you!
------------
Hello!!!
Wellcome to Python's world!
There are a lot of eresting things!
Enjoy yourself. Thank you!
利用这个就可以非常方便写些段落处理了比如处理缩进等思路方法如Cookbook书中例子:
复制代码 代码如下:

def addSpaces(s, numAdd):
white = " "*numAdd
white + white.join(s.splitlines(True))
def numSpaces(s):
[len(line)-len(line.lstrip( )) for line in s.splitlines( )]
def delSpaces(s, numDel):
numDel > min(numSpaces(s)):
raise ValueError, "removing more spaces than there are!"
'\n'.join([ line[numDel:] for line in s.splitlines( ) ])
def unIndentBlock(s):
delSpaces(s, min(numSpaces(s)))
