■ Set comprehension

◆ When described normally
s = set()
for i in range(10):
    s.add(i)
print(s)

◆ When described in set comprehension notation
s = {i for i in range(10)}
print(s)

result


{0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

You can also add an if statement.

s = {i for i in range(10) if i % 2 == 0}
print(s)
