A pairing function is a function that reversibly maps two non-negative integers onto a single non-negative integer.

This package currently supports the following pairing functions:

• Szudzik pairing function

Simply:

$ pip install pairing-functions 

from pairing_functions.szudzik import pairing pair((3, 4)) // 19 unpair(19) // (3, 4) 

You can also work with more than 2 integers:

pair((1, 2, 3, 4)) //1126 # by default, unpairing will result in two integers unpair(1126) // (33, 4) # but going back to the start is also possible - just specify how many integers you expect ! unpair(1126, n=4) // (1, 2, 3, 4) 

You can find more about pairing functions in the docs.
