python print输出到txt文件

import sys


class Logger(object):
    def __init__(self, fileN=\'Default.log\'):
        self.terminal = sys.stdout
        self.log = open(fileN, \'a\')

    def write(self, message):
        \'\'\'print实际相当于sys.stdout.write\'\'\'
        self.terminal.write(message)
        self.log.write(message)

    def flush(self):
        pass


sys.stdout = Logger(\'G:/2.0/test.txt\')  # 调用print时相当于Logger().write()

每次调用print都相当于调用Logger().write()，然后做了print本该做的事，打印到控制台，然后将内容保存到指定文件。
