strftime函数是Python中用于格式化日期和时间的函数,可以将日期和时间对象转换为特定格式的字符串。以下是一些strftime函数在时间处理中的技巧:
- 格式化日期和时间:
import datetime now = datetime.datetime.now() formatted_date = now.strftime("%Y-%m-%d %H:%M:%S") print(formatted_date)
输出结果类似于:2021-10-26 14:30:00
- 获取星期几:
weekday = now.strftime("%A") print(weekday)
输出结果为星期几的全称,比如:Tuesday
- 自定义格式化字符串:
custom_format = now.strftime("Today is %A, %B %d, %Y. The time is %I:%M %p.") print(custom_format)
输出结果为类似于:Today is Tuesday, October 26, 2021. The time is 02:30 PM.
- 将时间戳转换为日期时间字符串:
timestamp = 1635225000 date_time = datetime.datetime.fromtimestamp(timestamp).strftime("%Y-%m-%d %H:%M:%S") print(date_time)
输出结果类似于:2021-10-26 14:30:00
