It's a real shame that this fails:

How much precision do you want? Perhaps you really do want do just
use because you know you only have 2-3 places of precision in your
other numbers:
math.pi = 3.14
Or maybe you want to monkey-patch in a fraction/decimal instead for
greater precision:
math.pi =
decimal.Decimal('3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679')
It comes back to Python being a language for consenting adults.
