determining average grades and displaying letter grades
提问by RobertJRodriguez
I'm working on a program for class that finds the average of 5 entered test scores then displays the letter grades relevant to each letter score. letter score is a 10 point system ( A = 90-100 B = 80-89, etc)
我正在开发一个课程程序，该程序可以找到 5 个输入测试分数的平均值，然后显示与每个字母分数相关的字母等级。字母分数是 10 分制（A = 90-100 B = 80-89 等）
This is what I've put together so far but it doesn't seem to recognize "avg" in the syntax. any suggestions?
到目前为止，这是我整理的内容，但它似乎无法识别语法中的“avg”。有什么建议？
def main():
while true:
grade = int(input('Enter grade: '))
total += grade
avg = calc_average(total)
abc_grade = determine_grade(grade)
print('Average grade is: ' avg)
print('Letter grades for entered grades are: ' abc_grade)
def calc_average(total):
return total / 5
def determine_grade(grade):
if grade >= 90 and <= 100:
return 'A'
elif grade >= 80 and <= 89:
return 'B'
elif grade >= 70 and <= 79:
return 'C'
elif grade >= 60 and <= 69:
return 'D'
else:
return 'F'
main()

_list.append(grade)
avg = calc_average(sum(_list))
abc_grade = ' '.join([determine_grade(mark) for mark in _list])
if len(_list) > 5:
break
print('Average grade is: ', avg)
print('Letter grades for entered grades are: ', abc_grade)
回答by RMcG
use:
用：
print('Average grade is: '+str(avg))
print('Letter grades for entered grades are: '+abc_grade)
or
或者
print('Average grade is: %.2f'%(avg))
print('Letter grades for entered grades are: %s'%(abc_grade))

This Worked for me.. A few minor changes except your code is working fine.
这对我有用......除了你的代码工作正常之外，还有一些小的变化。
def main():
total = 0;avg = 0;abc_grade = 0
def calc_average(total):
return total / 5
def determine_grade(grade):
if 90 <= grade <= 100:
return 'A'
elif 80 <= grade <= 89:
return 'B'
elif 70 <= grade <= 79:
return 'C'
elif 60 <= grade <= 69:
return 'D'
else:
return 'F'
while(True):
grade = int(input('Enter grade: '))
total += grade
avg = calc_average(total)
abc_grade = determine_grade(grade)
print('Average grade is: ' + str(avg))
print('Letter grades for entered grades are: ' + str(abc_grade))
main()
Hope you can find out differences. :)
希望你能找出不同之处。:)

def main():
print("This is a program which displays the grade from a score")
print("")
grade = eval(input("What is the value of the score : "))
print("")
if 90 <= grade <= 100:
print("Your get an A")
elif 80 <= grade <= 89:
print("Your get a B")
elif 70 <= grade <= 79:
print("Your get a C")
elif 60 <= grade <= 69:
print("Your get a D")
else:
print("Your get an F")
main()
