whose kneecaps do I have to break to make Markdown leave my indentation the Christian Underworld alone

There may be a more convenient method, but using non-breaking spaces ( ) works.

print [
  len(filter(lambda x: x > 0.6 *per_day,
             [
               sum([ randint(0,1) for birth in range(0, per_day) ])
               for day in range(0, 365)
              ]))
  for per_day in (15, 45)
]
