So, my current very strict definition of similarity is:

2 pics are similar if my script gives for them value < 20%,
otherwise the pics are not similar.

Hi all,
I am trying to create a checklist which allows users to select a specific

to their PC. This is my first GUI attempt, and I don't imagine my issue is too

Well, thank you all for being honest ☺
What I conclude is that you, the programmers, don’t
really care about those who are new to programming: for most people out of the
programming world, I think it is simpler to be able to write: real(z), just as
you write: sin(z), abs(z), (z)^2 etc.
I'm starting to run out of ideas of what to do...I've imported the true
division (I'm using Python 2.7) to make sure I wasn't accidentally using any
integers but the results remain identical, so it's not a division problem.
I've copied the loop I'm running below, is there any mathematical operation

The main choices for arbitrary point precision seem to be mpmath (which is
pure python) and GMP (C++ but with python wrapper; GMP is heavily used in
academia)
