Python print输出重定向到文件和屏幕，超简单
import sys
import os
class Logger(object):
def __init__(self, filename="log.txt"):
self.terminal = sys.stdout
self.log = open(filename, "a")
def write(self, message):
self.terminal.write(message)
self.log.write(message)
def flush(self):
pass
path = os.path.abspath(os.path.dirname(__file__))
type = sys.getfilesystemencoding()
sys.stdout = Logger()
print(453453)
print(path)
print(type)
