Python Time & Space Complexity

Xmlrpc

xmlrpc Module¶

The xmlrpc module provides tools for XML-RPC (Remote Procedure Call) clients and servers, encoding procedure calls in XML.

Complexity Reference¶

Operation	Time	Space	Notes
`ServerProxy()`	O(1)	O(1)	Create client connection
RPC call	O(n)	O(n)	n = request/response size; network-bound
Server dispatch	O(1)	O(1)	Route to handler; method lookup

XML-RPC Client and Server¶

XML-RPC Client¶

import xmlrpc.client

# Create proxy - O(1)
server = xmlrpc.client.ServerProxy('http://example.com/rpc')

# Call remote function - O(n)
result = server.add(3, 4)
print(result)  # 7

# Call with complex types - O(n)
data = {'name': 'Alice', 'age': 30}
result = server.process_data(data)

XML-RPC Server¶

import xmlrpc.server
import socketserver

class MyFunctions:
    def add(self, a, b):
        return a + b

    def multiply(self, a, b):
        return a * b

# Create server - O(1)
server = xmlrpc.server.SimpleXMLRPCServer(('localhost', 8000))

# Register functions - O(1) each
server.register_instance(MyFunctions())

# Serve - O(m)
server.serve_forever()
