Python Logging (function name, file name, line number) using a single file
...re.
I'll start with the easiest: (3). Using logging you can aggregate all calls to a single log file or other output target: they will be in the order they occurred in the process.
Next up: (2). locals() provides a dict of the current scope. Thus, in a method that has no other arguments, you have ...
from list of integers, get number closest to a given value
...lone. Even if not, as long as you don't need to sort before every time you call take_closest, the bisect module will likely come out on top. If you're in doubt, try both and look at the real-world difference.
from bisect import bisect_left
def take_closest(myList, myNumber):

How do I initialize the base (super) class?
...found multiple ways of doing so.
For completeness sake, old-style classes call base methods explicitly using the base class, i.e.

class
...class (eigenclass). This allows you to specialise the behaviour of methods called on that specific object.
a = 'foo'
class << a
def inspect
'"bar"'
end
end
a.inspect # => "bar"
a = 'foo' # new object, new singleton class
a.inspect # => "foo"
Now, to answer the questio...
Are static fields inherited?

So the value of the static variable is incremented twice.

What you're looking for is called the data dictionary. In sqlite a list of all tables can be found by querying sqlite_master table (or view?)

.stop() is no longer available on the stream that gets passed to the callback.
The developer will have to access the tracks that make up the stream (audio or video) and stop each of them individually.
