Echo32

An example of a 32-bit echo server.

Echo32 is the 32-bit server class and Echo64 is the 64-bit client class. These Echo classes do not actually communicate with a library. The point of these Echo classes is to show that a Python data type in a 64-bit process appears as the same data type in the 32-bit process and vice versa. (provided that the data type is pickleable.)

Echo32

Echo32(host, port)

Bases: Server32

Example that shows Python data types are preserved between Echo32 and Echo64.

Parameters:

Name	Type	Description	Default
host	str	The IP address (or hostname) to use for the server.	required
port	int	The port to open for the server.	required

received_data staticmethod

received_data(*args, **kwargs)

Process a request from the Echo64.send_data method.

Parameters:

Name	Type	Description	Default
args	Any	The arguments.	()
kwargs	Any	The keyword arguments.	{}

Returns:

Type	Description
tuple[tuple[Any, ...], dict[str, Any]]	The args and kwargs that were received.
