[issue45349] configparser.ConfigParser: 2 newlines at end of file (EOF)

[Martin Panter]

Martin Panter  added the comment:

Looks like the same as Issue 32917. I presume there are two newlines at the end 
of the file because there are two newlines following every config section.

IMO this is a minor cosmetic annoyance, just like writing a key with an empty 
value gets you a trailing space after the equals sign at the end of the line. 
Not worth changing as a bug fix, and not worth a special option, but maybe okay 
to change if the code is simple and it doesn't harm compatibility.

[issue45349] configparser.ConfigParser: 2 newlines at end of file (EOF)

[Boštjan Mejak]

New submission from Boštjan Mejak :

In every Python version that I've tested, writing a config.ini file (utilizing 
configparser.ConfigParser), the result is such that the config.ini file has 2 
newlines at the end of the file.

The problem is that source code editors like Sublime Text, or IDEs like 
PyCharm, already insert a newline at the end of a file, but then 
configparser.ConfigParser 
(or maybe the Python's write() function?)  insert its own as well.

Is it possible to fix this behavior?
