1.简单的将日志打印到屏幕
import
logging
logging.
debug(
'This is debug message'
)
logging.
info(
'This is info message'
)
logging.
warning(
'This is warning message'
)
屏幕上打印:
WARNING:root:This is warning message
默认情况下，logging将日志打印到屏幕，日志级别为WARNING；
日志级别大小关系为：CRITICAL > ERROR > WARNING > INFO > DEBUG > NOTSET，当然也可以自己定义日志级别。
2.通过logging.basicConfig函数对日志的输出格式及方式做相关配置
import
logging
logging.
basicConfig(
level=
logging.
DEBUG,
format=
'%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s'
,
datefmt=
'%a, %d %b %Y %H:%M:%S'
,
filename=
'myapp.log'
,
filemode=
'w'
)
logging.
debug(
'This is debug message'
)
logging.
info(
'This is info message'
)
logging.
warning(
'This is warning message'
)
./myapp.log文件中内容为:
Sun, 24 May 2009 21:48:54 demo2.py[line:11] DEBUG This is debug message
Sun, 24 May 2009 21:48:54 demo2.py[line:12] INFO This is info message
Sun, 24 May 2009 21:48:54 demo2.py[line:13] WARNING This is warning message
logging.basicConfig函数各参数:
filename: 指定日志文件名
filemode: 和file函数意义相同，指定日志文件的打开模式，'w'或'a'
format: 指定输出的格式和内容，format可以输出很多有用信息，如上例所示:
%(levelno)s: 打印日志级别的数值
%(levelname)s: 打印日�
client:
import socket, sys
if __name__ == '__main__':

argv = sys.argv
if (len(argv)!=3) or (len(argv)==2 and argv[1]=='/?'):
print '>>>Useage:', argv[0], '<address> < ......
客户给一堆图片要传到后台，图片太大了，上百张图用photoshop改太慢，就想到用python写个简单的批处理。功能简单就是把原图按比例缩小，代码更简单 20多行。
# -*- coding: cp936 -*-
import Image
import glob, os
#图片批处理
def timage():
for files in glob.glob('D:\\1\\*.JPG'):
filepath,filena ......
