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)) 

运行结果：
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!
