Still playing around with this silly recursive function for permutating a positional notation

	def permute(n, chars='01', limit=128, start=0):
	appended = 0
	counter = 0

	def f(s, a):
	nonlocal appended

Prints a circumference of astronomical sizes in miles-feet-inches

	# Inspired by:
	# 'How many digits of pi do we really need?'
	# (https://www.jpl.nasa.gov/edu/news/2016/3/16/how-many-decimals-of-pi-do-we-really-need/)

	# digits amounted to only half of an inch at the scale of Voyager 1's
	# distance of ~12.5 billion miles
