Set Comprehensions

Concepts: pySetComprehension

Set comprehensions provide a concise, expressive way to create sets from iterables with optional filtering and transformation. If you are familiar with list comprehensions, set comprehensions follow the exact same syntax but use curly braces instead of square brackets. The result is a set with all duplicates automatically removed. The comprehension accomplishes the same result in one readable line. Both produce identical sets of squares from 1 to 25.

The third example filters the word list and naturally deduplicates, though in this case there were
