Hello Python-list,
I have an object which defines some methods. I want to join a list or
an iterable of those objects like this:
new_string = "|".join(iterable_of_custom_objects)
What is the __magic__ function that needs to be implemented for
this case to work? I though that __str__ is sufficient but it doesn't
seems to
work. Thanks in advance.
You need to do the string conversion yourself; .join() doesn't do it
for you, due to strong typing. It only accepts iterables of strings:
new_string = "|".join(str(x) for x in iterable_of_custom_objects)
You just have to implement __str__() python special method for your
"custom_objects".

Cheers,
