Python xdrlib Module
Example
Pack data into XDR format:
import xdrlib
packer = xdrlib.Packer()
packer.pack_int(42)
packer.pack_string(b'Hello')
data = packer.get_buffer()
print(f'Packed data: {data}')

Definition and Usage
The xdrlib module converts between Python data types and XDR (External Data Representation) format.
Use it when you need to exchange binary data between different computer systems in a platform-independent way.
Note: This module is deprecated since Python 3.11 and will be removed in Python 3.13. XDR is rarely used in modern applications.
