Pytz常用时区按偏移量排序

Question

我创建了这个函数来获得带有偏移量的两元组公共时区.

[(item, datetime.datetime.now(pytz.timezone(item)).strftime('%z') + " " + item) for item in pytz.common_timezones]

我从函数中得到了类似的东西

[('Africa/Abidjan', '+0000 Africa/Abidjan'), ('Africa/Accra', '+0000 Africa/Accra'), ('Africa/Addis_Ababa', '+0300 Africa/Addis_Ababa'), ('Africa/Algiers', '+0100 Africa/Algiers'), ('Africa/Asmara', '+0300 Africa/Asmara'), ('Africa/Bamako', '+0000 Africa/Bamako'), ('Africa/Bangui', '+0100 Africa/Bangui'), ('Africa/Banjul', '+0000 Africa/Banjul'), ('Africa/Bissau', '+0000 Africa/Bissau'), ('Africa/Blantyre', '+0200 Africa/Blantyre'), ('Africa/Brazzaville', '+0100 Africa/Brazzaville'), ('Africa/Bujumbura', '+0200 Africa/Bujumbura'), ('Africa/Cairo', '+0200 Africa/Cairo'), ('Africa/Casablanca', '+0100 Africa/Casablanca'), ('Africa/Ceuta', '+0200 Africa/Ceuta'), ('Africa/Conakry', '+0000 Africa/Conakry'), ('Africa/Dakar', '+0000 Africa/Dakar'), ('Africa/Dar_es_Salaam', '+0300 Africa/Dar_es_Salaam'), ('Africa/Djibouti', '+0300 Africa/Djibouti'), ('Africa/Douala', '+0100 Africa/Douala'), ('Africa/El_Aaiun', '+0000 Africa/El_Aaiun'), ('Africa/Freetown', '+0000 Africa/Freetown'), ('Africa/Gaborone', '+0200 Africa/Gaborone'), ('Africa/Harare', '+0200 Africa/Harare'), ('Africa/Johannesburg', '+0200 Africa/Johannesburg'), ('Africa/Juba', '+0300 Africa/Juba'), ('Africa/Kampala', '+0300 Africa/Kampala'), ('Africa/Khartoum', '+0300 Africa/Khartoum'), ('Africa/Kigali', '+0200 Africa/Kigali'), ('Africa/Kinshasa', '+0100 Africa/Kinshasa'), ('Africa/Lagos', '+0100 Africa/Lagos'), ('Africa/Libreville', '+0100 Africa/Libreville'), ('Africa/Lome', '+0000 Africa/Lome'), ('Africa/Luanda', '+0100 Africa/Luanda'), ('Africa/Lubumbashi', '+0200 Africa/Lubumbashi'), ('Africa/Lusaka', '+0200 Africa/Lusaka'), (

如何通过偏移对其进行排序？目前是ASC排序

我不确定我是否能正确理解你,但你可以试试这个:

>>> tz = [(item, datetime.datetime.now(pytz.timezone(item)).strftime('%z') + " " + item) for item in pytz.common_timezones]
>>> sorted(tz, key=lambda x: int(x[1].split()[0]))
[('Pacific/Midway', '-1100 Pacific/Midway'), ('Pacific/Niue', '-1100 Pacific/Niue'), ('Pacific/Pago_Pago', '-1100 Pacific/Pago_Pago'), ('Pacific/Honolulu', '-1000 Pacific/Honolulu'), ...
