平均列表中的数字

Question

找出 5 个数字 求数字的平均值

#import statistics
print("enter 5#s")
num1 = int(input())
num2 = int(input())
num3 = int(input())
num4 = int(input())
num5 = int(input())
numbers = [num1, num2, num3, num4, num5]
numsum = sum(numbers)
print("sum is:", numsum)
#Above list is working
#fix below
def Average(numbers):
    return sum(numbers) / len(numbers)
print("AVG = ", round(Average, 2))

错误 回溯（最近一次通话最后）： 文件“main.py”，第 15 行 print("AVG = ", round(Average, 2)) TypeError: 类型函数定义_round_method

Answer 1

最后一行（对print的调用）

def Average(numbers):
    return sum(numbers) / len (numbers)
    print("AVG = ", round(Average, 2))

需要不缩进（向左移动，在函数外部）并且需要以numbers 作为参数调用函数，如下所示：

def Average(numbers):
    return sum(numbers) / len (numbers)
print("AVG = ", round(Average(numbers), 2))

您的代码可以简化和改进，可能是这样的：

num_list = []
for i in range(5):
    s = input('Enter the {}. number: '.format(i+1))
    n = int(s)
    num_list.append(n)

the_sum = sum(num_list)
print('Sum:', the_sum)

the_avg = round(the_sum / len(num_list), 2)
print('Avg:', the_avg)

示例运行：

Enter the 1. number: 7
Enter the 2. number: 5
Enter the 3. number: 4
Enter the 4. number: 4
Enter the 5. number: 4
Sum: 24
Avg: 4.8

Answer 2

需要在末尾多加一行，应该是：

Average(numbers)
