  • set

  • Sets in Python are used when we are primarily interested in operations that we know from the set theory.

  • See also the Venn diagrams.

  • In day to day speach we often use the word "group" instead of "set" even though they are not the same.

  • What are the common elements of two set (two groups).

  • Is one group (set) the subset of the other?

  • What are all the elements that exist in both groups (sets)?

  • What are the elements that exist in exactly one of the groups (sets)?
