I see that you are correct. It seems that selecting all the text in a
text file (in Notepad), then hitting the delete key doesn't guarantee
that the file will be left truly blank. The way that consistently
works for me is to place the cursor in the upper left corner of the
file and hold down the delete key.

Running

with open("C:/test/test.txt", "w") as file_object:
      print(file=file_object)

Also works.

But that makes me wonder if there isn't a simpler way to do it with
Python -- to delete the contents of a file without deleting the file?
