Left-alignment is achieved by using a negative width.

You can use the locale module to generate thousands-separated numeric
string representations:

>>> from locale import *
>>> setlocale(LC_ALL, '') # locale is otherwise 'C'
'en_US.UTF-8'
>>> locale.format("%12.3f", 123456.789, grouping=False)
'  123456.789'
>>> locale.format("%12.3f", 123456.789, grouping=True)
' 123,456.789'
