Python;计算每个学生的三个年级的平均值
问题描述:
我必须编写代码来计算每个学生的三个年级的平均值,并根据得到的平均成绩显示一条消息。Python;计算每个学生的三个年级的平均值
该计划需要能够处理任何数量的学生;但每个学生只有3个等级。我必须使用一种方法来计算每个学生的平均分数,并根据平均值确定适当的信息。
这是我到目前为止的代码,我坚持:
def main():
more = 'y'
while more == 'y' and more == 'Y':
numScore = int(input('How many test score per student: '))
for numtest in range(numScore):
print ("The score for test")
score = int(input(': '))
total += score
total = 0
print ("Student number", students + 1)
print ('-----------------------------------------')
avg = getAvg(numScore)
if avg > 90:
print ("You're doing excellent work")
elif avg > 85 and avg <= 90:
print("You are doing pretty good work")
elif avg > 70 and avg <= 85:
print ("You better get busy")
else:
print ("You need to get some help")
def getAvg (numScore):
avg = total/numScore
print ("The average for student number", student + 1, \ "is:", avg)
more = input('Do you want to enter another student test score and get the average score of the student (Enter y for yes and n for no): ')
main()
答
你有最脚本正确的元素,但你需要更多地考虑一切的秩序。
确保您传递了函数所需的任何参数。您的getAvg
函数需要三个参数来计算平均值并将其与学生号一起显示。你也忘了返回average
。
当计算avg
范围,如果为>90
第一测试,然后根据定义下一elif avg > 85
将小于或等于90
所以它仅需要然后测试>85
。
下已经重新安排了一下工作:
def getAvg(student, total, numScore):
average = total/numScore
print ("The average for student number", student, "is:", average)
return average
def main():
student = 0
more = 'y'
while more == 'y':
student += 1
total = 0
numScore = int(input('How many test scores per student: '))
for test_number in range(numScore):
print ("The score for test", test_number+1)
score = int(input(': '))
total += score
print ("Student number", student)
print ('-----------------------------------------')
avg = getAvg(student, total, numScore)
if avg > 90:
print ("You're doing excellent work")
elif avg > 85:
print("You are doing pretty good work")
elif avg > 70:
print ("You better get busy")
else:
print ("You need to get some help")
print()
print('Do you want to enter another student test score and get the average score of the student?')
more = input('Enter y for yes, and n for no: ').lower()
main()
给你以下类型的输出:
How many test scores per student: 3
The score for test 1
: 93
The score for test 2
: 89
The score for test 3
: 73
Student number 1
-----------------------------------------
The average for student number 1 is: 85.0
You better get busy
Do you want to enter another student test score and get the average score of the student?
Enter y for yes, and n for no: n
+0
