复制代码 代码如下:

mulLine = """Hello!!!

Wellcome to Python's world!

There are a lot of interesting things!

Enjoy yourself. Thank you!"""

print ''.join(mulLine.splitlines())

print '------------'

print ''.join(mulLine.splitlines(True))

输出结果：

Hello!!! Wellcome to Python's world! There are a lot of interesting things! Enjoy yourself. Thank you!

------------

Hello!!!

Wellcome to Python's world!

There are a lot of interesting things!

Enjoy yourself. Thank you!

利用这个函数，就可以非常方便写一些段落处理的函数了，比如处理缩进等方法。如Cookbook书中的例子：

复制代码 代码如下:

def addSpaces(s, numAdd):

white = " "*numAdd

return white + white.join(s.splitlines(True))

def numSpaces(s):

return [len(line)-len(line.lstrip( )) for line in s.splitlines( )]

def delSpaces(s, numDel):

if numDel > min(numSpaces(s)):

raise ValueError, "removing more spaces than there are!"

return 'n'.join([ line[numDel:] for line in s.splitlines( ) ])

def unIndentBlock(s):

return delSpaces(s, min(numSpaces(s)))
