Question

找到5个数字查找数字的平均值

#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))

错误追溯（最近一次呼叫过去）：文件“ main.py”，位于第15行 print（“ AVG =”，round（Average，2）） TypeError：类型函数santnt define_round_method

Answer 1

您需要在末尾添加额外的一行，该行应为：

Average(numbers)

Answer 2

最后一行（对proxy: secretToken: "7891e9825fde46bee0ac2de2961a256909a7233c68b5893d863c3122168332e3" hub: db: type: sqlite-memory singleuser: image: name: jupyter/minimal-notebook tag: 2343e33dec46 profileList: - display_name: "Minimal environment" description: "To avoid too much bells and whistles: Python." default: true storage: extraVolumes: - name: jupyterhub-shared persistentVolumeClaim: claimName: nfs-claim1 extraVolumeMounts: - name: jupyterhub-shared mountPath: "/mnt/jovyan/shared"的调用）

print

需要不缩进（向左移动，在函数外部），并且需要使用def Average(numbers): return sum(numbers) / len (numbers) print("AVG = ", round(Average, 2))作为参数来调用函数，如下所示：

numbers

您的代码可以得到简化和改进，也许像这样：

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

样品运行：

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)

列表中的平均数
