Echo

This example illustrates that Python data types are preserved when they are passed from the Echo64 client to the Echo32 server and back. The Echo32.received_data method simply returns a tuple of the (args, kwargs) that it received back to the Echo64.send_data method in the client.

Create an Echo64 instance

>>> from msl.examples.loadlib import Echo64
>>> echo = Echo64()

send a boolean as an argument

>>> echo.send_data(True)
((True,), {})

send a boolean as a keyword argument

>>> echo.send_data(boolean=True)
((), {'boolean': True})

send multiple data types as arguments and as keyword arguments

>>> echo.send_data(1.2, {"my_list":[1, 2, 3]}, 0.2j, range(10), x=True, y="hello world!")
((1.2, {'my_list': [1, 2, 3]}, 0.2j, range(0, 10)), {'x': True, 'y': 'hello world!'})

You have access to the server's stdout and stderr streams when you shut down the server

>>> stdout, stderr = echo.shutdown_server32()
