我有以下代码可以清空输出缓冲区.

I have the following code to flushing out the output buffer.

print 'return 1'
sys.stdout.flush()

我可以设置打印功能，以便在调用缓冲区时自动刷新缓冲区吗?

Can I setup the print function so that it automatically flushes the buffer when it's called?

推荐答案

您可以使用-u标志以无缓冲模式启动python，例如

You can start python in unbuffered mode using the -u flag, e.g.

python -u script.py

或

#!/usr/bin/env python -u

作为脚本的"shebang"标题.

as "shebang" header for your script.
