I use Spyder mainly, also have Geany, SciTe, and Emacs setup but I like
Spyder for pyLint right there, console inside, the ability to run

You can just open the file again in write mode which will truncate it
for you.
So, f = open(filename, 'w') will clear the contents of your filename
(don't forget to close the file when you're done if you do this though).

You could also use split to get rid of the Flag_of_ by doing

Obviously if you want to keep the original log line then you will need
