Using paramiko, how could I get the stdout of exec_command() in real time instead of after completion?

Question

Using Python and paramiko, I have the following code

(stdin, stdout, stderr) = self.client.exec_command(x)
b = stderr.readlines()
if b:
    for i in b:
        print i
a = stdout.readlines()
if a:
    for i in a:
        print i

The command I run takes ~15 minutes and outputs a steady update to stdout, but it won't print on the host side until it's completed.

Is there a way to get the live stdout as opposed to waiting? Thanks.

Just repeatedly call stdout.readlines(). It will trigger flushing if any data in buffer.
