  Fix-up and clean-up docs for int.bit_length().

  * Replace dramatic footnote with in-line comment about possible round-off errors in logarithms of large numbers.
  * Add comments to the pure python code equivalent.
  * replace floor() with int() in the mathematical equivalent so the type is correct (should be an int, not a float).
  * add abs() to the mathematical equivalent so that it matches the previous line that it is supposed to be equivalent to.
  * make one combined example with a negative input.

The advantage of borrowing over owning a reference is that you don't need to

when a premature exit is taken. The disadvantage of borrowing over leaking is
when a premature exit is taken. The disadvantage of borrowing over owning is
that there are some subtle situations where in seemingly correct code a borrowed

This is an advanced function that is not needed in everyday Python
programming.
The function is invoked by the :keyword:`import` statement. It mainly exists
so that you can replace it with another function that has a compatible
interface, in order to change the semantics of the :keyword:`import`
statement. See the built-in module :mod:`imp`, which defines some useful
operations out of which you can build your own :func:`__import__` function.
This function is invoked by the :keyword:`import` statement. It can be
replaced (by importing the :mod:`builtins` module and assigning to
``builtins.__import__``) in order to change semantics of the
:keyword:`import` statement, but nowadays it is usually simpler to use import
hooks (see :pep:`302`). Direct use of :func:`__import__` is rare, except in
cases where you want to import a module whose name is only known at runtime.
For example, the statement ``import spam`` results in the following call:
``__import__('spam', globals(), locals(), [], -1)``; the statement
``from spam.ham import eggs`` results in ``__import__('spam.ham', globals(),
locals(), ['eggs'], -1)``. Note that even though ``locals()`` and ``['eggs']``
are passed in as arguments, the :func:`__import__` function does not set the
local variable named ``eggs``; this is done by subsequent code that is generated
for the import statement. (In fact, the standard implementation does not use
its *locals* argument at all, and uses its *globals* only to determine the
package context of the :keyword:`import` statement.)
The function imports the module *name*, potentially using the given *globals*
and *locals* to determine how to interpret the name in a package context.
The *fromlist* gives the names of objects or submodules that should be
imported from the module given by *name*. The standard implementation does
not use its *locals* argument at all, and uses its *globals* only to
determine the package context of the :keyword:`import` statement.
*level* specifies whether to use absolute or relative imports. The default
is ``-1`` which indicates both absolute and relative imports will be
attempted. ``0`` means only perform absolute imports. Positive values for
*level* indicate the number of parent directories to search relative to the
directory of the module calling :func:`__import__`.
When the *name* variable is of the form ``package.module``, normally, the
top-level package (the name up till the first dot) is returned, *not* the
module named by *name*. However, when a non-empty *fromlist* argument is
given, the module named by *name* is returned. This is done for
compatibility with the :term:`bytecode` generated for the different kinds of import
statement; when using ``import spam.ham.eggs``, the top-level package
:mod:`spam` must be placed in the importing namespace, but when using ``from
spam.ham import eggs``, the ``spam.ham`` subpackage must be used to find the
``eggs`` variable. As a workaround for this behavior, use :func:`getattr` to
extract the desired components. For example, you could define the following
helper::
given, the module named by *name* is returned.
def my_import(name):
mod = __import__(name)
components = name.split('.')
for comp in components[1:]:
mod = getattr(mod, comp)
return mod
For example, the statement ``import spam`` results in bytecode resembling the
following code::
spam = __import__('spam', globals(), locals(), [], -1)
*level* specifies whether to use absolute or relative imports. The default is
``-1`` which indicates both absolute and relative imports will be attempted.
``0`` means only perform absolute imports. Positive values for *level* indicate
the number of parent directories to search relative to the directory of the
module calling :func:`__import__`.
The statement ``import spam.ham`` results in this call::
spam = __import__('spam.ham', globals(), locals(), [], -1)
Note how :func:`__import__` returns the toplevel module here because this is
the object that is bound to a name by the :keyword:`import` statement.
On the other hand, the statement ``from spam.ham import eggs, sausage as
saus`` results in ::
_temp = __import__('spam.ham', globals(), locals(), ['eggs', 'sausage'], -1)
eggs = _temp.eggs
saus = _temp.sausage
Here, the ``spam.ham`` module is returned from :func:`__import__`. From this
object, the names to import are retrieved and assigned to their respective
names.
If you simply want to import a module (potentially within a package) by name,
you can get it from :data:`sys.modules`::
>>> import sys
>>> name = 'foo.bar.baz'
>>> __import__(name)
<module 'foo' from ...>
>>> baz = sys.modules[name]
>>> baz
<module 'foo.bar.baz' from ...>

is left as an exercise for the reader.
