Question

我必须创建一个程序来收集成绩，取平均值，然后打印最高和最低平均值以及用户名。我正在使用前一周的分配代码来获取用户输入并计算平均值，但我正在努力弄清楚如何从这些计算的平均值中检测高/低值。一旦检测到这些高/低值，我也不确定从哪里开始重新打印相关的名称信息。任何帮助将不胜感激！

def main():

    numuser=eval(input("How many users are there?: "))
    numgrade=eval(input("How many grades will there be for each user?: "))
    usercount=0
    gradecount=0

    grade(numuser,numgrade,usercount,gradecount)

def grade(nu,ng,uc,gc):
    name=[]
    while uc <= nu:
        first=input("Please enter the student's first name: ")
        last=input("Please enter the student's last name: ")
        name.append(last)
        ID=input("Please enter the student's ID: ")
        gradetot=0

        total=[]
        grades=[]
        while gc < ng:
            gradeval=eval(input("Please enter the grade: "))
            total.append(gradeval)
            gradetot=gradetot+gradeval
            gc=gc+1

            avg=gradetot/gc
            grades.append(avg)

            low=min(grades)
            high=max(grades)

        nu=nu-1
        uc=uc+1
        gc=0

        print("The average grade for", first, last, ID, "is :", avg)

    if uc>nu:
        print("The lowest average is ", low, "and the highest average is", high)

main()

您必须将学生姓名及其平均成绩的数据存储在字典中。然后你可以使用字典方法检索

您在主循环中使用＆gt; =迭代次数更多，这意味着要求用户输入更多记录

如果您要打印用户名及其成绩信息，则必须将其存储在词典中

def main():

numuser=eval(input("How many users are there?: "))
numgrade=eval(input("How many grades will there be for each user?: "))
usercount=0
gradecount=0

grade(numuser,numgrade,usercount,gradecount)

def grade(nu,ng,uc,gc): dct={} while uc < nu: first=input("Please enter the student's first name: ") last=input("Please enter the student's last name: ") ID=input("Please enter the student's ID: ") gradetot=0

    total=[]
    while gc < ng:
        gradeval=eval(input("Please enter the grade: "))
        total.append(gradeval)

        average=[]
        gradetot=gradetot+gradeval
        average.append(gradetot)
        avg=gradetot/(gc+1)
        gc=gc+1
        dct[first+last]=avg  
        #Getting errors here with trying to find a mechanism to detect values from a calculated average
        #nu=nu-1
    uc=uc+1
    gc=0


print dct    
maxkey, maxvalue = max(dct.items(), key=lambda x:x[1])

print("The highest grade obtained by", maxkey, "is :",maxvalue )

""" nu=nu-1 uc=uc+1 gc=0

if uc>nu:
    print("The lowest average is ", low, " and the highest is ", high)
    #Need to print the names that go along with the grades
