Python Time Operation example and time formatting parameter Summary

1. Method for retrieving the specific time in the past:
Copy codeThe Code is as follows:
#! /Usr/bin/python

Import time
# Obtain the current time of the previous day
Time. strftime ('% Y-% m-% d % t', time. localtime (time. time ()-24*60*60 ))

# Obtain the current time 15 days ago
Time. strftime ('% Y-% m-% d % t', time. localtime (time. time ()-15*24*60*60 ))

# The first two hours of the current time 15 days ago
Time. strftime ('% Y-% m-% d % t', time. localtime (time. time ()-15*24*60*60-2*60*60 ))

2. method for getting the specific time in the future:
Copy codeThe Code is as follows:
#! /Usr/bin/python
Import time

# Obtain the current specific time after one day
Time. strftime ('% Y-% m-% d % t', time. localtime (time. time () + 24*60*60 ))

# Obtain the current time in 20 days
Time. strftime ('% Y-% m-% d % t', time. localtime (time. time () + 20*24*60*60 ))

# Take the first two hours of the current time in 20 days
Time. strftime ('% Y-% m-% d % t', time. localtime (time. time () + 20*24*60*60-2*60*60 ))

3. Take only the past and future values of a certain time unit:
Copy codeThe Code is as follows:
#! /Usr/bin/python
Import time

# Last month
Time. localtime () [1]-1

# Last Year
Time. localtime () [0]-1

# Take the month after two months
Time. localtime () [1] + 2
