Today I've talked about some of the Python's practical local tool modules

Loggin Module for logging

#!/usr/bin/env python#--*--coding:utf-8--*--import logginglogging.basicconfig (filename= ' Wgwtest.log ' ,  #filename代表记录的日志文件名称                      format= '% (asctime) s - % (name) s - % (levelname) s  -% (module) s:  % (message) s ',                      #日志格式参数   include modify time   user name of launcher   log alarm level   Program name   Alarm information for logging                      datefmt= '%y-%m-%d %h:%m:%s %p ',                      #日志中asctime的时间格式                       level=logging. DEBUG)                       #设置日志等级, set to print only this level and alarms above this level                       #默认的等级是logging. warning# Alarm Message (message) s content logging.debug ( ' Debug ') logging.info (' info ') logging.warning (' Warning ') logging.error (' Error ') logging.critical (' critical ')

The printed log content is

2015-12-04 16:21:15 pm-root-debug-wgwtest:debug2015-12-04 16:21:15 pm-root-info-wgwtest:info2015-12-04 16:21 : pm-root-warning-wgwtest:warning2015-12-04 16:21:15 pm-root-error-wgwtest:error2015-12-04 16:21:15 pm-r Oot-critical-wgwtest:critical

In the parameters of the log format, there are a lot of things you can do to set the

% (Levelno) S: Print the value of the log level

% (levelname) S: Print log level name

% (pathname) s: Prints the path of the currently executing program, which is actually sys.argv[0]

% (filename) s: Prints the current name of the executing program

% (funcName) s: Print the current function of the log

% (Lineno) d: Print the current line number of the log

% (asctime) s: Time to print logs

% (thread) d: Print thread ID

% (threadname) s: Print thread name

% (process) d: Print process ID

% (message) s: Print log information

Log print level from high to low

CRITICAL  = 50 FATAL  = CRITICAL ERROR  = 40 WARNING  = 30 WARN  = WARNING INFO  = 20 DEBUG  = 10 NOTSET  = 0

Time Module

Import timeprint time.strftime ('%y-%m-%d ', Time.localtime ()) #格式化实现本地当前时间

2015-12-04 18:21:18

Import Timeprint Time.asctime (Time.localtime ()) #以文字形式显示的日期

Fri Dec 04 18:33:10 2015

DateTime module

Import Datetimeprint Datetime.datetime.now (). Strftime ('%y-%m-%d%h:%m:%s ') #获取当前时间

2015-12-04 18:37:42

Import Datetimeprint Datetime.datetime.now ()-Datetime.timedelta (days=5) #获取5天前的日期2015-11-29 18:44:33.063000

Import Datetimeprint Datetime.datetime.now () + Datetime.timedelta (minutes=30) #获取30分钟后的时间2015-12-04 19:18:35.263000

Shutil Module

For advanced operations on files, folders, you can copy files or folders and compress folders
