In Python, there are two builtin functions for turning an object into a string:
str is supposed to be a friendly, human readable string.
repr is supposed to include detailed information about an object's contents (sometimes, they'll return the same thing, such as for integers). By convention, if there's a Python expression that will eval to another object that's ==,
repr will return such an expression e.g.
>>> print repr('hi') 'hi' # notice the quotes here as opposed to... >>> print str('hi') hi
If returning an expression doesn't make sense for an object,
repr should return a string that's surrounded by < and > symbols e.g.
To answer your original question:
class Foo: def __init__(self, foo): self.foo = foo def __eq__(self, other): """Implements ==.""" return self.foo == other.foo def __repr__(self): # if you eval the return value of this function, # you'll get another Foo instance that's == to self return "Foo(%r)" % self.foo

Adding to the replies given above,
'%r' can be useful in a scenario where you have a list with heterogeneous data type.
Let's say, we have a
list = [1, 'apple' , 2 , 'r','banana']
Obviously in this case using
'%s' would cause an error. Instead, we can use
'%r' to print all these values.

The difference between
%r calls the
repr() method and
%s calls the
str() method. Both of these are built-in Python functions.
repr() method returns a printable representation of the given object.
str() method returns the "informal" or nicely printable representation of a given object.
In simple language, what the
str() method does is print the result in a way which the end user would like to see:
name = "Adam" str(name) Out: 'Adam'
repr() method would print or show what an object actually looks like:
name = "Adam" repr(name) Out: "'Adam'"
