吐槽一下測評網的筆試居然只支持 Python 2，害我在 input 上面搞了好久

from random import random
def getNumber(lst):
    mn = min(lst)
    notIn = []
    swift = 0
    for i in range(len(lst)):
            if lst[i] != mn + i + swift:
                    notIn += [mn + i + swift]
                    swift += 1
    return notIn

def getLst():
    a = int(random() * 10000)
    b = int(random() * 10000)
    c = int(random() * 10000)
    lst = []
    for i in range(10000):
            if i != a and i != b and i != c:
                    lst += [i]
    return lst

lst = getLst()

def main():
    a = input().split(' ')
    for i in range(len(a)):
            a[i] = int(a[i])
    n = getNumber(a)
    num = int(str(n[0]) + str(n[1]) + str(n[2]))
    print(num%7)

if '__name__' == '__main__':
    main()
