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:
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：
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)))
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!
