It's not always easy or convenient to call .replace(",", "_") on the
output of format:
"With my help, the {} caught {:,d} ants.".format("aardvark", 100000000)
would need to be re-written as something like:
py> "With my help, the {} caught {} ants.".format("aardvark",
"{:,d}".format(100000000).replace(",", "_"))
'With my help, the aardvark caught 100_000_000 ants.'
