\n 表示换行
\t 表示一个制表符
\\ 表示 \ 字符本身
print ('Bob said \"I\'m OK\"')
任务
请将下面两行内容用Python的字符串表示并打印出来：
Python was started in 1989 by "Guido".
Python is free and easy to learn.
print ('Python was started in 1989 by "Guido".\nPython is free and easy to learn.')
如果一个字符串包含很多需要转义的字符，对每一个字符都进行转义会很麻烦。为了避免这种情况，我们可以在字符串前面加个前缀r ，表示这是一个 raw 字符串，里面的字符就不需要转义了。
print (r'\(~_~)/ \(~_~)/')===打印结果为\(~_~)/ \(~_~)/
任务
请把下面的字符串用r'''...'''的形式改写，并用print打印出来：
'\"To be, or not to be\": that is the question.\nWhether it\'s nobler in the mind to suffer.'
print (r'''"To be, or not to be": that is the question.
Whether it's nobler in the mind to suffer.''')
