Python的datetime可以处理2种类型的时间,分别为offset-naive和offset-aware。前者是指没有包含时区信息的时间,后者是指包含时区信息的时间,只有同类型的时间才能进行减法运算和比较。datetime模块的函数在默认情况下都只生成offset-naive类型的datetime对象,例如now()、utcnow()、fromtimestamp()、utcfromtimestamp()和...
Between dealing with time zones, daylight saving time, and different written date formats, it can be tough to keep track of which days and times you’re referencing. Fortunately, the built-in Python datetime module can help you manage the complex nature of dates and times.In this tutorial, ...
Example 1: datetime to string using strftime() The program below converts a datetime object containing current date and time to different string formats. from datetime import datetime now = datetime.now() # current date and time year = now.strftime("%Y") print("year:", year) month = now...

The dateutil.parser.parse() function is more flexible than datetime.strptime() as it can automatically detect and parse a variety of date formats without requiring a predefined format string: from dateutil.parser import parse date_str1 = '2023-03-01' date_str2 = 'March 1, 2023' date_...
