Question

我做了一些研究并在 Python 中编写了一个程序来以这种格式显示回历（伊斯兰历）日期...

weekday_name, date, month, year

我想在我的一个应用程序中使用它。只是想知道我的代码是否正确。我离日历专家还差得很远。我很困惑我的代码是否遗漏了任何东西，最后日期误导了人们！任何人都可以检查代码并让我知道我做错了什么吗？

#Get current date.
import datetime
now = datetime.datetime.now()
year = now.year
month = now.month
day = now.day
weekday_number = now.weekday()

#Convert current date to Julian date.
from calverter import Calverter
cal = Calverter()
julian = cal.gregorian_to_jd(year,month,day)


#Convert Julian date to Islamic date.
hijri = cal.jd_to_islamic(julian)


#Convert Islamic date to weekday_name, day_number, month_name, year format.
hijri_year = hijri[0]
hijri_month = hijri[1]
hijri_day_number = hijri[2]
hijri_date = [weekday_number, hijri_day_number, hijri_month, hijri_year]


#Convert hijri_month (which are in number forms) into month names.
if hijri_month == 1:
    hijri_date[2] = "Muharram"
elif hijri_month == 2:
    hijri_date[2] = "Safar"
elif hijri_month == 3:
    hijri_date[2] = "Rabi al Awwal"
elif hijri_month == 4:
    hijri_date[2] = "Rabi ath Thani"
elif hijri_month == 5:
    hijri_date[2] = "Jamada al Ula"
elif hijri_month == 6:
    hijri_date[2] = "Jumada ath Thaniyah"
elif hijri_month == 7:
    hijri_date[2] = "Rajab"
elif hijri_month == 8:
    hijri_date[2] = "Shaban"
elif hijri_month == 9:
    hijri_date[2] = "Ramadan"
elif hijri_month == 10:
    hijri_date[2] = "Shawal"
elif hijri_month == 11:
    hijri_date[2] = "Dhu al Qa'dah"
elif hijri_month == 12:
    hijri_date[2] = "Dhu al Hijah"


#Convert weekday_numbers into weekday names.
if weekday_number == 0:
    hijri_date[0] = "Al Ithnayn"
elif weekday_number == 1:
    hijri_date[0] = "Ath Thulatha"
elif weekday_number == 2:
    hijri_date[0] = "Al Arbia"
elif weekday_number == 3:
    hijri_date[0] = "Al khamis"
elif weekday_number == 4:
    hijri_date[0] = "Al Jumuah"
elif weekday_number == 5:
    hijri_date[0] = "As Sabt"
elif weekday_number == 6:
    hijri_date[0] = "Al Ahad"

print hijri_date

我用 pycalverter 库做了一些事情。如果有人想要，我可以 post pastebin 中的开源 pycalverter 代码。

我有几点建议。

首先，如果您不确定，您的代码是否正确（即使您确定）- 编写运行测试。你可以使用一个测试库（比如unittest and etc.) or just implement some simple tests to make sure everything is working as you expect. If you are new to testing, you can find a lot of articles网上关于它的

其次，您所有的 if 都可以替换为两个列表（一个用于月，一个用于天）：

# Just define 12 months names:
islamic_months = ["Muharram", "Safar", "Rabi al Awwal", 
                  "Rabi ath Thani", "Jamada al Ula", 
                  "Jumada ath Thaniyah", "Rajab", "Shaban", 
                  "Ramadan", "Shawal", "Dhu al Qa'dah", "Dhu al Hijah"]
# On the next step get the right name: 
hijri_date[2] = islamic_months[hijri_month - 1] # 1 <= hijri_month <= 12

天数也一样：

islamic_day_names = ["Al Ithnayn", "Ath Thulatha", "Al Arbia",
                     "Al khamis", "Al Jumuah", "As Sabt", "Al Ahad"]
hijri_date[0] = islamic_day_names[weekday_number] # 0 <= weekday_number <= 6

主要思想是您不必检查是哪一天或哪一个月。只需使用它的索引从列表中获取正确的名称。
