Answers for "__repr__ in python"

__repr__ or __str__

very briefly
 - The default implementation is useless (it’s hard to think of one which wouldn’t be, but yeah)
 - __repr__ goal is to be unambiguous
 - __str__ goal is to be readable
 - Container’s __str__ uses contained objects’ __repr__
 
see source for more info
