如何使已打开的文件可读（例如sys.stdout）？

您可以使用以下代码：

import sysfrom builtins import print as builtin_printmyfile = "output.txt"def print(*args):    builtin_print(*args, file=sys.__stdout__)    # prints to terminal    with open(myfile, "a+") as f:        builtin_print(*args, file=f)    # saves in a file

这应该重新定义该

print

stdout
