pyephem - 带有Pyrephem的月相的人类可读名称

Question

看来pyephem应该能够给我您在月球周期中所处位置的标准人型名称，并指定日期-“第一季度”，“满月”，“打蜡新月”，“渐渐隆起， ”等

我说不对吗？

有谁知道标准解决方案吗？

Answer 1

这是我对自己的问题的快速而肮脏的解决方案。假定observer与系统时区位于同一时区，但这对我而言已经足够。

仍然让人感到惊讶的是，ephephem并没有比这更精致的东西，但是也许出于天文学的原因，我不够聪明，无法理解。

import ephem

def human_moon(observer):
    target_date_utc = observer.date
    target_date_local = ephem.localtime( target_date_utc ).date()
    next_full = ephem.localtime( ephem.next_full_moon(target_date_utc) ).date()
    next_new = ephem.localtime( ephem.next_new_moon(target_date_utc) ).date()
    next_last_quarter = ephem.localtime( ephem.next_last_quarter_moon(target_date_utc) ).date()
    next_first_quarter = ephem.localtime( ephem.next_first_quarter_moon(target_date_utc) ).date()
    previous_full = ephem.localtime( ephem.previous_full_moon(target_date_utc) ).date()
    previous_new = ephem.localtime( ephem.previous_new_moon(target_date_utc) ).date()
    previous_last_quarter = ephem.localtime( ephem.previous_last_quarter_moon(target_date_utc) ).date()
    previous_first_quarter = ephem.localtime( ephem.previous_first_quarter_moon(target_date_utc) ).date()
    if target_date_local in (next_full, previous_full):
        return 'Full'
    elif target_date_local in (next_new, previous_new):
        return 'New'
    elif target_date_local in (next_first_quarter, previous_first_quarter):
        return 'First Quarter'
    elif target_date_local in (next_last_quarter, previous_last_quarter):
        return 'Last Full Quarter'
    elif previous_new < next_first_quarter < next_full < next_last_quarter < next_new:
        return 'Waxing Crescent'
    elif previous_first_quarter < next_full < next_last_quarter < next_new < next_first_quarter:
        return 'Waxing Gibbous'
    elif previous_full < next_last_quarter < next_new < next_first_quarter < next_full:
        return 'Waning Gibbous'
    elif previous_last_quarter < next_new < next_first_quarter < next_full < next_last_quarter:
        return 'Waning Crescent'
