[Python-ideas] Add list.join() please

[Jimmy Girardet]

Hi,

At the end this long thread because 2 functions doing quite the same
thing have the same name but not the same signature and it's confusing
for some people (I'm one of those)

|str.||join|(/iterable/)

|os.path.||join|(/path/, /*paths/)


There are strong arguments about why it's implemented like that and why
it's very difficult to change it.

Maybe some change could be giving str.join 1 iterable or many args :
about str.join:
   a - if 0 arg : error
   b - if 1 arg : process or return error if not iterable
   c - if > 1 arg: do b using all args as one iterable

maybe some performance issues could go against it.

I agree with the fact that this is a minor need and it should not allow
major change
