[New-bugs-announce] [issue33160] Negative values in positional access inside formatting

[Facundo Batista]

New submission from Facundo Batista <facundo at taniquetil.com.ar>:

This works fine:

>>> "{[0]}".format([1, 2, 3])
'1'

This should work too:

>>> "{[-1]}".format([1, 2, 3])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list indices must be integers or slices, not str
