Hi all
C:\Users\E7280>python
Python 3.9.7 (tags/v3.9.7:1016ef3, Aug 30 2021, 20:19:38) [MSC v.1929 64
bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>> x = list(range(10))
>>>
>>> '{x[1]}'.format(**vars())
'1'
>>>
>>> '{x[-1]}'.format(**vars())
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: list indices must be integers or slices, not str
>>>
Can anyone explain this error? It seems that a negative index is deemed
to be a string in this case.
Thanks
Frank Millman
