平均分计算器

Question

我已经对数组使用了sum函数。我需要使用它，这样如果列表变大，总数仍然正确。但我总是出错。 这是我的代码：

print("please enter your 5 marks below")



#read 5 inputs

mark1 = input("enter mark 1: ")

mark2 = input("enter mark 2: ")

mark3 = input("enter mark 3: ")

mark4 = input("enter mark 4: ")

mark5 = input("enter mark 5: ")

#create array/list with five marks

marksList = [mark1, mark2, mark3, mark4, mark5]

#print the array/list

print(marksList)

#calculate the sum and average

sumOfMarks = sum(marksList)

averageOfMarks = sum(marks_ist)/5

#display results

print("The sum of your marks is: "+str(sumOfMarks))

print("The average of your marks is: "+str(averageOfMarks))

Answer 1

这是因为输入是字符串而不是int

mark1 = int(input("enter mark 1: "))
