Question

我对编码很新，我正在尝试在Python 3中编写以下代码：

How many students?: 4
How many units?: 3
What is the name of student 1?: John
What did John get in unit 1?: 34
34 out of 100 is a Fail.
What did John get in unit 2?: 67
67 out of 100 is a Credit.
What did John get in unit 3?: 52
52 out of 100 is a Pass.
On average, John is getting a Pass.

然后，对所有4名学生进行此操作后，该计划必须说：最高分为（学生姓名），平均分为（学生分数）。

这是我到目前为止所拥有的。如何让它像上面一样单独循环学生信息？我一个接一个地出来。

numStudent = int (input('Please enter number of students: '))
numUnit = int(input('Please enter the number of units for your course: '))

for i in range(numStudent):
      studentName = input('Please enter students first name: ')

for j in range(numUnit):

    unitmark = int(input('what did' + ' ' + studentName + ' ' + 'get for unit:'))

def calculateGrade(unitmark):

    if unitmark <= 49:
        Print(unitmark,"out of 100 You are failing")
    elif unitmark <= 59:
        return(unitmark,"out of 100 is a Pass")
    elif unitmark <=69:
        return(unitmark, "out of 100 is a Credit")
    elif unitmark <= 79:
        return(unitmark, "out of 100 is a Distinction")
    elif unitmark <=100:
        return(unitmark, "out of 100 is a High Distinction")

print(calculateGrade(unitmark))           

totalGrade = numUnit + unitmark

averageGrade = totalGrade / 100

print(round (averageGrade, 7))

Answer 1

这是解决方案。在IDLE中运行或者如果您在Linux上运行它在终端中运行，例如python3.6 ./grades.py（指定正确的Python版本并创建grades.py）

def get_grade(score, name=None):
    if score <= 49:
        grade = "You are failing"
    elif score <= 59:
        grade = "is a Pass"
    elif score <= 69:
        grade =  "is a Credit"
    elif score <= 79:
        grade =  "is a Distinction"
    elif score <= 100:
        grade =  "is a High Distinction"

    if not name:
        print(score, "out of 100", grade)
    else:
        print('On average,', name, grade)

num_students = int(input('How many students?: '))
num_units = int(input('How many units?: '))

students_db = {}

for student_num in range(1, num_students+1):
    student_name = input('\nWhat is the name of student %s?: ' % student_num)

    current_student_total_scores = 0
    for unit_num in range(1, num_units+1):
        unitmark = int(input('\nWhat did %s get in unit %s?: ' % (student_name, unit_num)))
        current_student_total_scores += unitmark
        get_grade(unitmark)

    avarage_score = current_student_total_scores/num_units
    get_grade(avarage_score, student_name)

    students_db.update({student_name: avarage_score})

name, avg_score = max(students_db.items(), key = lambda p: p[1])
print('\nThe top score is %s with an average score of %s' % (name, avg_score))
