Joining a list of python objects with __str__ method

Question

I\'ve already looked at this question on representing strings in Python but my question is slightly different.

Here\'s the code:

>>> class W         


        

Answer 1

Would it work for you if you added an __add__ method? E.g.,

from operator import add
from random import randint

class WeirdThing(object):
    def __init__(self,me=None):
        self.me = me if me else chr(randint(97,122))
    def __str__(self):
        return "%s" % self.me
    def __repr__(self):
        return ";%s;" % self.me
    def __add__(self,other):
        new_me = add(str(self.me),str(other.me))
        return WeirdThing(new_me)

weird_list = [WeirdThing(), WeirdThing(), WeirdThing()]
print weird_list

gives,

[;y;, ;v;, ;u;]

and this,

strange_thing = reduce(add,weird_list)
print strange_thing

gives,

yvu
