[Python-Dev] Python3: speed efficiency vs user friendliness (my first experience)

[anatoly techtonik]

I didn't touch Python3 until PyCon, and my first user experience is
not really good. I've got a feeling that Python3 became more ugly,
because it doesn't allow me to think about the logic anymore, and
requires more low-level workarounds even for basic user input/output.

For example, now I need to remember that on Windows I need to flush
output every time when I want the result of print() with end!='\n' to
appear on the screen immediately. And for the most of my legacy
scripts I used end='\n' when I want to output some progress to user. I
am surprised to know this never worked on Linux, but what I really
didn't expect is to see that choice is made not in user's favor, but
in a favor of speed. This way we'll be writing in a cross-platform
assembly language named 'Python' soon. =)
