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:

1 mulLine = """Hello!!! 2  Wellcome to Python's world! 3     There are a lot of interesting things! 4         Enjoy yourself. Thank you!""" 5  6 print(''.join(mulLine.splitlines())) 7 print('------------') 8 print(''.join(mulLine.splitlines(True))) 9 10 results:11 12 Hello!!! Wellcome to Python's world!    There are a lot of interesting things!        Enjoy yourself. Thank you!13 ------------14 Hello!!!15  Wellcome to Python's world!16     There are a lot of interesting things!17         Enjoy yourself. Thank you!
