Message246606
Expressions such as
a + not b
a * not b
+ not b
- not b
raise a SyntaxError, for instance :
>>> 0 + not 0
File "<stdin>", line 1
0 + not 0
^
SyntaxError: invalid syntax
>>> - not 0
File "<stdin>", line 1
- not 0
^
SyntaxError: invalid syntax
>>>
if the not expression is wrapped in parenthesis, expected evaluation occurs:
>>> - not 0
File "<stdin>", line 1
- not 0
^
SyntaxError: invalid syntax
>>> 0 + (not 0)
1
>>> - (not 0)
-1
>>>
