python-3.x - 这个python源代码有什么问题

Question

当我使用以下命令执行此源代码时:1 2 3 4

population = int(input()).split()
def get_deviation(population):
    average = float(sum(population))/float(population)
    s = 0
    for n in population:
        s += float((n-average)**2)

    deviation = float(s**0.5)    
    print(deviation)

    get_deviation(population)    

我收到此错误:

population = int(input()).split()
ValueError: invalid literal for int() with base 10: '1 2 3'

Answer 1

average = float(sum(population))/float(population)

这行没有任何意义。您不能将数字除以列表。

尝试

average = float(sum(population))/float(len(population))

希望能有所帮助。
