Thank you; I can confirm that overriding __repr__ makes the list display as I
wanted.
The decision to use repr inside the list seems very odd, given the context,
namely formatting something for display or looking for a simple string
representation. It seems more natural to me to use str or, if in a format, the
default formatting all the way down. Is there a good reason it's repr?
Given a string, say:
>>> s = 'foo'
str shows:
>>> print(str(s))
whereas repr shows:
>>> print(repr(s))
'foo'
If it was in a list, would you want it to show:
[foo]
or:
['foo']
?
Another example:
>>> foo = 'ham, eggs, cheese'
>>> bar = 'bacon, toast'
if list used str instead of repr:
>>> print(list(foo, bar))
[ham, eegs, cheese, bacon, toast]
How many items are in that list? (Hint: it isn't 5. ;)
