Python time manipulation examples and time formatting parameters summary

1. How to take the time of the past:

#!/usr/bin/python  Import Time  #取一天前的当前具体时间   time.strftime ('%y-%m-%d%T ', Time.localtime (Time.time ()-24 *60*60))  #取15天前的当前具体时间   time.strftime ('%y-%m-%d%T ', Time.localtime (Time.time () -15*24*60*60))  # Take 15 days before the current specific time of the first 2 hours   time.strftime ('%y-%m-%d%T ', Time.localtime (Time.time () -15*24*60*60-2*60*60))

2. How to take the specific time in the future:

#!/usr/bin/python   Import Time  #取一天后的当前具体时间   time.strftime ('%y-%m-%d%T ', Time.localtime (Time.time () +24 *60*60))   #取20天后的当前具体时间   time.strftime ('%y-%m-%d%T ', Time.localtime (Time.time () +20*24*60*60))   #   time.strftime ('%y-%m-%d%T ', Time.localtime (Time.time () +20*24*60*60-2*60*60) for the first 2 hours of the current specific time after 20 days

3. Take only a certain time unit past, future specific values:

#!/usr/bin/python   Import Time  #取上一月月份   time.localtime () [1]-1   #取去年年份   time.localtime () [0]-1   #取两个月后的月份   time.localtime () [1]+2
