The python comma (monzo: [-23 16 -1⟩, ratio: 43046721/41943040) is a medium 5-limit comma which is the product of 81/80 and the pythagorean comma. Tempering out this comma leads to the rank-2 python temperament generated by a slightly flat 3/2 that is very near 12edo's rendition of it in the optimized tuning.

The name was coined by CompactStar in 2023 as a combination of pythagorean comma and syntonic comma.
