[issue9618] IDLE shell ignores all but first statement

[Cherniavsky Beni]

New submission from Cherniavsky Beni <cben at users.sf.net>:

[Spinoff of http://bugs.python.org/issue3559]

If you manage to type several simple statements into the prompt (by copy-pasting them, using Ctrl+J, or creative deletion), IDLE runs the first one and silently ignores the rest:

>>> x = 1
x = 2
>>> x
1

Moreover, it doesn't even parse the additional lines:

>>> x = 3
$@syntax error?!
>>> x
3

If the first statement is a compound statement, IDLE refuses with a SyntaxError at the begging of the second statement:


>>> def f():
	return 42
f()
SyntaxError: invalid syntax


I believe in both cases the right least-surprise behavior is to run all statements.

If not, a clear error explaining that IDLE doesn't support multiple statements must be printed.  But I can't see a reason to choose this over making it Just Work.
