Python中的splitlines用来分割行。当传入的参数为True时,表示保留换行符 \n。通过下面的例子就很明白了
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:
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)))
