3. Using contextlib.redirect_stdout() functionAnother option is using contextlib.redirect_stdout() function in Python 3.4 which sets up a context manager for redirecting sys.stdout to another file. Here’s a working example:1 2 3 4 5 6 7 import contextlib path = 'path/to/some/dir/...
2>>filename # Redirect and append stderr to file "filename." &>filename # Redirect both stdout and stderr to file "filename." # This operator is now functional, as of Bash 4, final release. M>N # "M" is a file descriptor, which defaults to 1, if not explicitly set. # "N"...
contextlib.redirect_stdout(new_target) 用于临时将sys.stdout重定向到另一个文件或file-like 对象的上下文管理器。 该工具为输出硬连线到标准输出的现有函数或类增加了灵活性。 例如,help()的输出通常被发送到sys.stdout。您可以通过将输出重定向到io.StringIO对象来捕获字符串中的输出。替换流从__enter__方法返...
