sorted는 파이썬 내장 정렬 함수라, 같은 이름의 변수를 정의하면 함수 참조가 가려집니다.
이후에 sorted 호출 시 혼동을 일으킬 수 있으니, pq 같은 변수명을 사용하는게 좋을 것 같습니다.

그렇네요. 인터뷰용으로만 쓰다 보니 이런 부분을 놓치네요. 감사합니다.

힙큐를 이용해 단순 정렬을 원하시면 heapify로 힙을 구성한 뒤, sorted()로 정렬하는 편이 더 효율적이고, 단순 sorted(numSet)을 호출하셔도 동일한 결과를 얻으실 수 있으십니다.

감사합니다. 일단 heapify로 해두었습니다. 기록용으로 heapq 풀이법 먼저 생각해두었던 것을 남겨둔 거라서요.
