Python中将打印输出日志文件

一. 利用sys.stdout将print行导向到你定义的日志文件中，例如：

import sys # make a copy of original stdout route stdout_backup = sys.stdout
# define the log file that receives your log info log_file = open("message.log", "w")
# redirect print output to log file sys.stdout = log_file print "Now all print info will be written to message.log" # any command line that you will execute ... log_file.close() # restore the output to initial pattern sys.stdout = stdout_backup print "Now this will be presented on screen"
