Python has two ways to convert an object to a string:
str is supposed to be user-readable, and
repr is more technical, e.g. for debugging purposes.
To my surprise, if I have a list of things,
repr(list) do the same thing and include a
repr of each item. I would expect
str(list) to include
str of the list items, and
repr(list) to include
repr of the items.
Apparently, I am not alone: back in 2008 this was proposed by Oleg Broytman and Jim J. Jewett (PEP 3140), but rejected, because “Guido said it would cause too much disturbance too close to Beta“. It is causing disturbance ever since, I suppose…
