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：
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
weekday = now.strftime("%A")
print(weekday)
输出结果为星期几的全称，比如：Tuesday
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.
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
