Lento (current release: v301024) is a highly minimalist Python package (the entire API consists of a single class Part and a main processor function proc!) for compiling Lilypond sheet music.

For more information and examples please check the Documentation.

Some Coding Tips

Convert a collection of durations into a progressing beats collection by utilizing itertools.accumulate:

from random import choice
from itertools import accumulate

durs = [choice([.25, .5, .75, 1]) for _ in range(4)]
beats = list(accumulate(durs, initial=0))
print("Durations", durs)
print("Beats", beats)

# Durations: [0.25, 0.5, 0.5, 0.75]
# Beats: [0, 0.25, 0.75, 1.25, 2.0]
