长字符串

　　要表示很长的字符串(跨越多行的字符串)，可使用三个单引号或三个双引号。

>>> print('''This is a long story.            >>> print("""This is a long story.
... It continues here.                　　　　　... It continues here.
... And it not over yet.                      ... And it not over yet.
... Hello World''')                           ... Hello World""")
This is a long story.                         This is a long story.
It continues here.                    　　　　 It continues here.
And it not over yet.                    　　   And it not over yet.
Hello World                        　　　　　　 Hello World

　　常规字符串也可跨越多行，只要在行尾加上反斜杠(‘\’)，但其只输出一行。

>>> print('This is a long story.\
... It continues here.\
... And it not over yet.\
... Hello World')
This is a long story.It continues here.And it not over yet.Hello World
