First, if you have long numbers, you should maybe like add underscores or something. Underscores are actually like totally ignored by Python but they make it easier for humans to read.
one_milli = 1_000_000
one_billi = 1_000_000_000You should most definitely use humanize.
It’s like totally amazing.
import humanize
humanize.intcomma(1_000_000)
# '1,000,000'
humanize.intword(1_500_000_000)
# '1.5 billion'
humanize.scientific(4_600_000_000_000)
# '4.60 x 10¹²'
humanize.ordinal(22)
# '22nd'
humanize.naturalsize(8_192)
# '8.2 kB'
humanize.naturalsize(8_192, binary=True)
# '8.0 KiB'
