问题描述
**感谢您在计算与分数平均值相对应的平均字母等级方面的所有帮助。 我还需要列出每个年级和相应的字母年级。 我对如何执行此操作有些困惑。 我是否可以执行其他功能来打印此内容？
def main():
student_name = input('Please enter your first and last name: ')
scores = askForScore()
avg_score = calc_average(scores)
letter_grade = determine_grade(avg_score)
print(student_name)
print('The average of 8 tests is', letter_grade)
print('letter_grade\tnumber_grade')
print('--------------------------')
def askForScore():
score1 = float(input('Please enter the first test score:'))
score2 = float(input('Please enter the second test score:'))
score3 = float(input('Please enter the third test score:'))
score4 = float(input('Please enter the fourth test score:'))
score5 = float(input('Please enter the fifth test score:'))
score6 = float(input('Please enter the sixth test score:'))
score7 = float(input('Please enter the seventh test score:'))
score8 = float(input('Please enter the eigth test score:'))
return (score1, score2, score3, score4, score5, score6, score7, score8)
def calc_average(scores):
avg_score = (scores[0] + scores[1] + scores[2] + scores[3] + scores[4] + scores[5] + scores[6] + scores[7]) / 8
return avg_score
def determine_grade(avg_score):
if avg_score >= 90 and avg_score <= 100:
return 'A'
elif avg_score >= 80 and avg_score <= 89:
return 'B'
elif avg_score >= 70 and avg_score <= 79:
return 'C'
elif avg_score >= 60 and avg_score <= 69:
return 'D'
else:
return 'F'
main()

干得好。 有一些问题。
1）从函数返回值时，需要将其分配给变量，以便可以将其传递给下一个函数。
2）字符串文字（如字母等级“ F”）必须放在单引号或双引号中。
def main():
student_name = input('Please enter your first and last name: ')
scores = askForScore()
avg_score = calc_average(scores)
letter_grade = determine_grade(avg_score)
print(letter_grade)
def askForScore():
score1 = float(input('Please enter the first test score:'))
score2 = float(input('Please enter the second test score:'))
score3 = float(input('Please enter the third test score:'))
score4 = float(input('Please enter the fourth test score:'))
score5 = float(input('Please enter the fifth test score:'))
return (score1, score2, score3, score4, score5)
def calc_average(scores):
avg_score = (scores[0] + scores[1] + scores[2] + scores[3] + scores[4]) / 5
return avg_score
def determine_grade(avg_score):
if avg_score >= 90 and avg_score <= 100:
return 'A'
elif avg_score >= 80 and avg_score <= 89:
return 'B'
elif avg_score >= 70 and avg_score <= 79:
return 'C'
elif avg_score >= 60 and avg_score <= 69:
return 'D'
else:
return 'F'
main()

确保您了解一些Python概念，例如变量的范围，返回语句和函数参数。
在你的情况，例如， score1 ... score5内askForScore是不是“可读” calc_average 。
实际上， calc_average返回所需的值，并且这些值需要作为如下参数传递给下一个函数：
...
score1, score2, score3, score4, score5 = askForScore()
calc_average(score1, score2, score3, score4, score5)
...
