So in Python format, you have something like this:

I have done that. The best article I have found is:

So far I have tried exifread, exiftool, mediainfo, but looks like I will have
to combine several tools in order to get the information that I need.
Major problem is with the model. Looks like every manufac

Dear All,
Summary of the question:
Is it generally safe to dynamically change an objects class; if not
under which conditions can it be considered safe.
Context:
Given the code below, I have no direct control over Base and M1. M1
is a instantiated by 'calling' the read-only property of Base.

I have a GTK TreeView with scrollbars which enables me to scroll
through the values OK. Clicking on a row selects it and highlights
it.
However if one uses 'down arrow' to move the selection/highlight down
the list then the selected row disappears from the visibble window.
How can I scroll the w

*Generally* safe? No. You cannot expect to take an arbitrary object and

You can subclass M2 from M1 and override only what you need.

This is a simplified example of a Monte Carlo
simulation where random vectors (here 2D vectors,
which are all zero) are summed (the result is in
r1 and r2 or r, respectively):
def case1():
import numpy as np
M = 10
N = 1
r1 = np.zeros(M)
r2 = np.zeros(M)

Sometimes I have a short term requirement to serve some data by http, so
I've been using those modules rather than setting up a full featured web
