There are many ways to deal with this:
- 
Use r before the string to avoid any errors, this will parse the string without giving errors.
 
For example:
 s= r”some very long string …”
- 
Using escape characters \ to use it in strings add one more \. This means \\ without and space in between
 
- 
Can use triple quotation marks, be careful to use only three quotation marks.
   " " " a very long string ......            
 ....multiple lines
        " " " 
Hope this helps.
