Getting Started with Python (i) Defining a string +raw string with multiple lines of string

Defining strings

We've explained what strings are in front of us. Strings can be ‘‘ expressed in or "" enclosed.

What if the string itself contains ‘ ? For example, if we want to represent  I‘m OK  a string, we can say it in " " parentheses:

"I ' m OK"

Similarly, if a string is contained " , we can use it as a ‘ ‘ means of enclosing:

' Learn ' Python "in Imooc '

What if the string contains ‘ and contains both " ?

At this point, you need to "escape" some special characters of the string , and the Python string is \ escaped.

To represent a stringBob said "I‘m OK".
Because ' and ' can cause ambiguity, so we insert a representation before it that \ this is an ordinary character and does not represent the beginning of the string, so the string can be represented as

' Bob said \ ' i\ ' m ok\ '. '

Note: the escape character \ does not count toward the contents of the string.

The usual escape characters are:

\ n indicates a newline \ t means a tab \ \ means \ character itself

Task

Please print the following two lines in a Python string:

Python is started in 1989 by "Guido".

Python is free and easy to learn.

Raw strings and multiple lines of string

If a string contains many characters that need to be escaped, it can be cumbersome to escape each character. To avoid this, we can prefix the string to r indicate that it is a raw string, and that the characters inside it do not need to be escaped. For example:

R ' \ (~_~)/\ (~_~)/'

However r‘...‘ , the notation cannot represent multiple lines of string, nor can it represent ‘ " A string containing and (why?). )

If you want to represent multiple lines of string, you can use the ‘‘‘...‘‘‘ expression:

"Line 1Line 2Line 3"

The above string is represented in exactly the same way as the following:

' Line 1\nline 2\nline 3 '

You can also add the multiline string to r a raw string by adding it in front of it:

R ' ' Python is created by ' Guido '. It's free and easy to learn. Let's start learn Python in imooc! '

Task

Please rewrite the following string in r‘‘‘...‘‘‘ the form of print:

' \ ' to being, or not to be\ ": That's the Question.\nwhether it\ ' s nobler in the mind to suffer. '
