Usage examples:
'New messages: %s' % humanize.Commas(star_count)
-> 'New messages: 58,192'
'Found %s.' % humanize.Plural(error_count, 'error')
-> 'Found 2 errors.'
'Found %s.' % humanize.Plural(error_count, 'ox', 'oxen')
-> 'Found 2 oxen.'
'Copied at %s.' % humanize.DecimalPrefix(rate, 'bps', precision=3)
-> 'Copied at 42.6 Mbps.'
'Free RAM: %s' % humanize.BinaryPrefix(bytes_free, 'B')
-> 'Free RAM: 742 MiB'
'Finished all tasks in %s.' % humanize.Duration(elapsed_time)
-> 'Finished all tasks in 34m 5s.'
These libraries are not a substitute for full localization. If you
need localization, then you will have to think about translating
strings, formatting numbers in different ways, and so on. Use
ICU if your application is user-facing. Use these libraries if
your application is an English-only internal tool, and you are
tired of seeing "1 results" or "3450134804 bytes used".

r( r c C s t | | | t d | d | �S)a� Formats an integer and a unit into a string, using decimal prefixes.
The unit will be prefixed with an appropriate multiplier such that
the formatted integer is less than 1,000 (as long as the raw integer
is less than 10**27). For example:
DecimalPrefix(576012, 'bps') -> '576 kbps'
DecimalPrefix(576012, '') -> '576 k'
DecimalPrefix(576, '') -> '576'
DecimalPrefix(1574215, 'bps', 2) -> '1.6 Mbps'
Only the SI prefixes which are powers of 10**3 will be used, so
DecimalPrefix(100, 'thread') is '100 thread', not '1 hthread'.

BinaryPrefix()
Args:
quantity: A number.
unit: A string, the dimension for quantity, with no multipliers (e.g.
"bps"). If quantity is dimensionless, the empty string.
precision: An integer, the minimum number of digits to display.
min_scale: minimum power of 1000 to scale to, (None = unbounded).
max_scale: maximum power of 1000 to scale to, (None = unbounded).
Returns:
A string, composed by the decimal (scaled) representation of quantity at the
required precision, possibly followed by a space, the appropriate multiplier
and the unit.

Sd S)a� Convert a number into a string that might include a unicode fraction.
This method returns the integer representation followed by the closest
fraction of a denominator 2, 3, 4, 5 or 8.
For instance, 0.33 will be converted to 1/3.
The resulting representation should be less than 1/16 off.
Args:
number: a python number
spacer: an optional string to insert between the integer and the fraction
default is an empty string.
Returns:
a unicode string representing the number.

This key function results in a lexigraph sort. For example:
- ['1, '3', '20'] (not ['1', '20', '3']).
- ['Model 9', 'Model 70 SE', 'Model 70 SE2']
(not ['Model 70 SE', 'Model 70 SE2', 'Model 9']).
Usage:
new_list = sorted(old_list, key=humanize.NaturalSortKey)
or
list_sort_in_place.sort(key=humanize.NaturalSortKey)
Based on code by Steven Bazyl <sbazyl@google.com>.
Args:
data: str, The key being compared in a sort.
Returns:
A list which is comparable to other lists for the purpose of sorting.

tz: datetime.tzinfo object, timezone to use when formatting. Typical uses
might want to rely on datelib or pytz to provide the tzinfo object, e.g.
use datelib.UTC, datelib.US_PACIFIC, or pytz.timezone('Europe/Dublin').
Returns:
Formatted string like '2013-11-17 11:08:27.720000 PST'.
