This small program
mac2011% cat bug.py
print(__name__ == "__main__")
#if True:
if __name__ == "__main__":
print("main")
else:
print("not main")
works well in Terminal :
mac2011% python bug.py
True
main
mac2011% python --version
Python 3.6.9 :: Anaconda, Inc.
but it does not work in Emacs python mode :
mac2011% Emacs -Q bug.py
(version)
"GNU Emacs 28.0.50 (build 1, x86_64-apple-darwin15.6.0, NS appkit-1404.47
Version 10.11.6 (Build 15G22010))
of 2020-01-09"
Files opens in (Python ElDoc) mode
Python menu
Start interpreter (C-c C-p)
Eval buffer (C-c C-c)
Python 3.6.9 |Anaconda, Inc.| (default, Jul 30 2019, 13:42:17)
[GCC 4.2.1 Compatible Clang 4.0.1 (tags/RELEASE_401/final)] on darwin

>>> python.el: native completion setup loaded
>>> Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/alba/Documents/projets/plot time series/bug.py", line 5
else:
^
SyntaxError: invalid syntax
>>>
Replacing 'if __name__ == "__main__":' by 'if True:', there is no more error.
Replacing "__main__" by "__main_", there is no more error.
Same with Python 3.7.6.
'print("main") if __name__ == '__main__' else print("not main")' works.
Best regards.
