您有两种选择：

1. 打开一个日志文件，并用它而不是函数替换sys.stdout：

   log = open("myprog.log", "a")

   sys.stdout = log

   print(“Hello”)

   nothing is printed because it goes to the log file instead.

2. 用您的日志功能替换打印：

   # If you're using python 2.x, uncomment the next line

   from future import print_function

   print = log.info

   print(“Hello!”)

   nothing is printed because log.info is called instead of print
