Python the Hard Way - exercise 6 - %r versus %s

Question

http://learnpythonthehardway.org/book/ex6.html

Zed seems to use %r and %s interchangeably here, is there any difference between the two? Wh

Answer 1

The code below illustrates the difference. Same value prints differently:

x = "xxx"
withR = "prints with quotes %r"
withS = "prints without quotes %s"
