Razlika med obema nizoma v Pythonu je enaka razliki med številom elementov v dveh nizih. Funkcija razlika() vrne niz, ki je razlika med dvema nizoma. Poskusimo ugotoviti, kakšna bo razlika med dvema množicama A in B. Potem bodo (množica A – množica B) elementi prisotni v množici A, ne pa v B in (množica B – množica A) bodo prisotni elementi v kompletu B, vendar ne v kompletu A.
primer:
set A = {10, 20, 30, 40, 80} set B = {100, 30, 80, 40, 60} set A - set B = {10, 20} set B - set A = {100, 60} Explanation: A - B is equal to the elements present in A but not in B B - A is equal to the elements present in B but not in A> Oglejmo si Vennov diagram naslednje funkcije diferencialne množice. 
Sintaksa:
set_A.difference(set_B) for (A - B) set_B.difference(set_A) for (B - A)>
V tem programu bomo poskušali ugotoviti razliko med dvema nizoma set_A in set_B, v obeh smereh:
