本文主要是介绍Python splitlines使用技巧,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
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)))
