dateutil
模組擴充套件了Python標準庫中的
datetime
模組，提供了更廣泛的日期和時間處理功能。它支持解析多種日期時間格式、計算日期差異、處理時區轉換、生成重復事件規則等高級功能。
「安裝」
pip install python-dateutil
「使用」
「解析多種日期格式」
from dateutil import parser

date_str2 = "15th November, 2023"
parsed_date1 = parser.parse(date_str1)
parsed_date2 = parser.parse(date_str2)
print(f"Parsed Dates: {parsed_date1}, {parsed_date2}")「計算兩個日期之間的差異」
from datetime import datetime
from dateutil import relativedelta

from datetime import timedelta
