Python into the Pit

There are many characters in the string that need to be escaped, you need to add a lot \ , in order to simplify, Python also allows to use r‘‘ ‘‘ A string that represents the inside of the default is not escaped, you can try it yourself:

>>> print (' \\\t\\ ') \       

　　

>>> print (R ' \\\t\\ ')
\\\t\

If there is a lot of line wrapping inside the string, \n writing in a row is not good to read, in order to simplify, Python allows ‘‘‘...‘‘‘ a format to represent multiple lines of content, you can try it yourself:

>>> print ("' Line1 ... line2 ... line3") line1line2line3
