문제 풀이

import sys
import statistics as st


sys.stdin = open('input.txt', 'rt')
T = int(input())

for t in range(T):
    n = int(input())
    a = list(map(int, input().split()))
    mean = st.mean(a)
    ans = 0
    for x in a:
        if x <= mean:
            ans += 1
    print(f"#{t + 1}", ans)

statistics 모듈을 이용하여 풀었습니다.
