Python 3.7.1 (v3.7.1:260ec2c36a, Oct 20 2018, 14:05:16) [MSC v.1915 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> spam = 'spam'
>>> f'{spam[0}'
File "<stdin>", line 1
SyntaxError: f-string: expecting '}'
The error message seems wrong because a "]" is missing rather than a "}".

The same behavior applies to f'{spam[}' and f'{spam(}'. Also to f'{spam{}', but that might be expected.
This message is more clear:
>>> f'{spam('
File "<stdin>", line 1
SyntaxError: f-string: mismatched '(', '{', or '['
Perhaps you want to apply that to the above error cases. Then you wouldn't have to catch any type of bracket. :-)
