Which can be surprisingly useful in certain cases (I've used it for
debugging).
class Foo2:
def __init__(self):
self.name = 'This is my name'
self.value = 'This is my value'
def __repr__(self):
return "Name: %s\nValue: %s" % (self.name, self.value)
In [2]: a = Foo2()
In [3]: a
Out[3]:
Name: This is my name
Value: This is my value
In [4]: print a
------> print(a)
Name: This is my name
Value: This is my value
