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.
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 ......
" " "
Hope this helps.
