Serhiy Storchaka <storchaka+cpyt...@gmail.com> added the comment:
I cannot reproduce this behavior in 3.7+. `assert (0, 'bad')` does not have any
effect. But in 3.6 it outputs a traceback to the stderr.
$ ./python -m idlelib

SyntaxWarning: assertion is always true, perhaps remove parentheses?
But other syntax warnings are converted to errors in IDLE (reported by Raymond
in https://bugs.python.org/issue15248#msg349375).
In the regular interactive interpreter:
>>> 0 is 0
<stdin>:1: SyntaxWarning: "is" with a literal. Did you mean "=="?
True
>>> data = [
... (1, 2, 3) # oops, missing comma!
... (4, 5, 6)
... ]
<stdin>:2: SyntaxWarning: 'tuple' object is not callable; perhaps you missed a
comma?
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
TypeError: 'tuple' object is not callable
In IDLE:
>>> 0 is 0
SyntaxError: "is" with a literal. Did you mean "=="?
>>> data = [
(1, 2, 3) # oops, missing comma!
(4, 5, 6)
]
SyntaxError: 'tuple' object is not callable; perhaps you missed a comma?
