说明：
比如，有个长字符串，Put several strings within parentheses to have them joined together.但是我在写脚本的时候，
想要放在多行来写，如何进行切割
操作过程：
1.通过多个字符串的拼接，并且放入到括号中
>>> text = ('Put several strings within parentheses'
"to have them joined"
'together.')
>>> text
'Put several strings within parenthesesto have them joinedtogether.'
#注意：一定把所有字符串放入到括号中
>>> text = ('put' +
'ABc')
>>> text
'putABc'
备注：将多个字符串放入到括号中，然后还是使用之前的字符串拼接方式完成拼接。
