b = 'a  b'
c = 'a\tb'          # \t means put a tab in the string
d = 'aren\'t'       # \' means the ' is not the end of the string, just a character

# print ( "a = 'petrichor'" )
# print ( "b = 'a  b'" )
# print ( "c = 'a\\tb'" )       # \\ means that the second \ is a regular character
# print ( "d = 'aren\\\'t'" )   # \\ means that the second \ is a regular character to be included, then
# \' tells us that ' is also a regular character to be included in the string
