Say I've got a class...
class test(object):
def __init__(self):
self.foo = 1
self.bar = 2
self.baz = 3
I can say...
def __str__(self):
return "foo: {0}\nbar: {1}\nbaz: {2}".format(self.foo, self.bar, self.baz)
and everything's simple and clean and I can vary the formatting if I need to.
This gets ugly when the class has a lot of attributes because the string
construction gets very long.
I can do...
return "foo: {0}\nbar: {1}\nbaz: {2}".format(self.foo,
self.bar,
self.baz)
which is an improvement, but there's still a very long line.
And there's also something like...
return "\n".join((": ".join((str(k), str(self.__dict__[k]))) for k in
self.__dict__))
which is a nice length, but I lose control of the order of the attributes and
the formatting is fixed. It also looks a bit too much like Lisp ;o)
Is there a better way?
Cheers,
Drea
p.s. I may want to substitute __repr__ for __str__ perhaps?
