为什么我的代码会出现类型错误？

Question

我收到错误 TypeError: '<' not supported between instances of 'function' and 'int' 当我的代码在我的代码中达到 'if(entered_score < 60):' 时。我已经研究过这个话题，但我看到的所有例子和解释都很难适用于我的情况。我是使用 Python 的新手，所以如果有什么我忽略了，或者我对这件事完全一无所知，我并不感到惊讶。如果有人能指出给我，我将不胜感激。

def calc_average(score_1, score_2, score_3, score_4, score_5):
    average = (score_1 + score_2 + score_3 + score_4 + score_5) / 5
    return average

def determine_grade_letter(entered_score):
    if(entered_score < 60):
        return "F"
    elif(entered_score < 70):
        return "D"
    elif(entered_score < 80):
        return "C"
    elif(entered_score < 90):
        return "B"
    elif(entered_score < 101):
        return "A"

def enter_scores():
    score_1 = float(input("test score #1: "));
    score_2 = float(input("test score #2: "));
    score_3 = float(input("test score #3: "));
    score_4 = float(input("test score #4: "));
    score_5 = float(input("test score #5: "));

return score_1, score_2, score_3, score_4, score_5

def results(score_1, score_2, score_3, score_4, score_5):
    print("test score #1: " + str(score_1) + "\n\n" + "grade letter: " + 
determine_grade_letter(score_1), \
           "test score #2: " + str(score_2) + "\n\n" + "grade letter: " + 
determine_grade_letter(score_2), \
          "test score #3: " + str(score_3) + "\n\n" + "grade letter: " + 
determine_grade_letter(score_3), \
          "test score #4: " + str(score_4) + "\n\n" + "grade letter: " + 
determine_grade_letter(score_4), \
          "test score #5: " + str(score_5) + "\n\n" + "grade letter: " + 
determine_grade_letter(score_5), \
          "average score: " + str(calc_average(score_1, score_2, score_3, score_4, score_5)) + 
"\n" \
          + "grade leter: " + determine_grade_letter(calc_average))
def main():
    score_1, score_2, score_3, score_4, score_5 = enter_scores()
    results(score_1, score_2, score_3, score_4, score_5)

main()

Answer 1

首先： enter_scores 方法中的 return 位置不正确（需要制表符）

第二个：

在您的条件下，您将 return 多个变量的函数与一个整数

进行比较

您必须将其中一个数字与一个整数进行比较这可以帮助： Returning Multiple Values in Python

Answer 2

您在比较时使用的是函数。您应该使用带参数的函数。

determine_grade_letter(score_5), \
          "average score: " + str(calc_average(score_1, score_2, score_3, score_4, score_5)) + 
"\n" \
          + "grade leter: " + determine_grade_letter(calc_average(score_1, score_2, score_3, score_4, score_5)))
