Python Time Operation example and time formatting parameter Summary

This article mainly introduces the Python time operation examples, such as taking the last few days, the last few days, the last 30 days, and the last 30 days, and the last 30 days. For more information, see 1. Method of taking the past time:

The 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:

The 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:

The 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

Time. strftime () format command:

The Code is as follows:

% A abbreviation of the day of the week
% A full name of the day of the week
Abbreviation of % B month
% B full name
% C standard date time string
The last two digits of the Year % C
% D indicates the day of the month in decimal format.
% D month/day/year
% E indicates the day of the month in decimal format in the two-character field
% F-month-day
The last two digits of the Year % g. The year is based on the week.
