This issue was closed but I still see the problem in 3.7.2. Here's a snippet
with line numbers from IDLE:
01 Python 3.7.2 (default, Dec 30 2018, 08:59:00)
02 [Clang 9.1.0 (clang-902.0.39.2)] on darwin
03 Type "help", "copyright", "credits" or "license()" for more information.
04 >>> 1 + 2
05 3
06 >>> print('Hello')
07 Hello
08 >>> d = {1: 'uno', 2: 'dos', 3: 'tres}
09
10 SyntaxError: EOL while scanning string literal
11 >>> 1 + 2
12
13 3
14 >>>
Notice that IDLE is inserting an extra blank line at (12) above.
And here's a snippet with line numbers from the Python shell:
01 Python 3.7.2 (default, Dec 30 2018, 08:59:00)
02 [Clang 9.1.0 (clang-902.0.39.2)] on darwin
03 Type "help", "copyright", "credits" or "license" for more information.
04 >>> 1 + 2
05 3
06 >>> print('Hello')
07 Hello
08 >>> d = {1: 'uno', 2: 'dos', 3: 'tres}
09 File "<stdin>", line 1
10 d = {1: 'uno', 2: 'dos', 3: 'tres}
11 ^
12 SyntaxError: EOL while scanning string literal
13 >>> 1 + 2
14 3
15 >>>
Between lines (13) and (14) there is no extra blank line.
I'm sorry if my initial post was unclear. But the extra blank line is the bug
I'm describing. I don't think there should be an extra blank line between (11)
and (13) in the IDLE shell. This blank line persists for every input, even
after restarts.
I'm on macOS.
I would be interested in debugging the issue locally but I ran into a couple
issues trying to do so. When I check out the CPython sources and build the
python.exe executable, I get this error when trying to execute IDLE:
$ ./python.exe -m pdb -m idlelib.idle
> /Users/grantj/repos/cpython/Lib/idlelib/idle.py(1)<module>()
-> import os.path
(Pdb) c
Traceback (most recent call last):

IndexError: list assignment index out of range
If I comment out line 181 in /Users/grantj/repos/cpython/Lib/idlelib/macosx.py
then I can get IDLE to start. But it will later crash trying to display the
first tooltip:

This was the case for both the master (e9a044ec16) and the 3.7 (d7cb2034bb)
branch. Is there something extra I need to configure for a working build on
macOSX?
