用于计算平均课堂笔记的Python脚本

Question

对于一个乞讨者来说，我该如何编写一个程序来计算我的平均课堂笔记呢？我试着用def来做，但是我得到了类似这样的结果：

a1 = int(input("How many grades do you have? "))
def media_notelor(a=0,b=0,c=0,d=0,e=0,f=0,g=0,h=0,i=0,j=0,k=0,l=0,m=0,n=0,o=0,p=0,q=0,r=0,s=0,t=0,u=0,v=0,x=0,y=0,z=0):
    x = a+b+c+d+e+f+g+h+i+j+k+l+m+n+o+p+q+r+s+t+u+v+x+y+z
    ma = x/a1
    print(ma)

然后我需要一个循环？我能用什么?

Answer 1

你可以这样做

grades = []

while True:
    print("Insert your grade or a negative value to finish")
    grade = int(input())

    if grade < 0:
        break

    grades.append(grade)


print("The average is : " + str(sum(grades) / len(grades)))

Answer 2

您可以创建一个成绩列表，然后将其传递给以下函数：

def average(list_of_grades: list):
    summation = sum(list_of_grades)
    num_of_grades = len(list_of_grades)
    return summation / num_of_grades

Answer 3

您可以使用*args来完成此操作

def my_avg(*my_grades):
    print(float(sum(my_grades)) / len(my_grades)) # calculate avrage


number_of_grades = int(input('how many grades do you have')) # input how many grades do we have
grades = [] # list to store our grades
for i in range(number_of_grades):
    grades.append(int(input('Enter grade'))) # Inserting grades
my_avg(*grades)
