Terry J. Reedy <tjre...@udel.edu> added the comment:
To avoid such questions, bug reports should contain exception messages and
usually at least some of the tracebacks.
>>> ''[0]
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
''[0]
IndexError: string index out of range
>>> x=None
>>> x[0]
Traceback (most recent call last):
File "<pyshell#3>", line 1, in <module>
x[0]
TypeError: 'NoneType' object is not subscriptable
IndexError should mean object was indexable.
Operations on None should give TypeError.
