為什么在定義變量時出現名稱錯誤？

Question

def calculate_letter_grades(test_score):
        if test_score >= 90:
            return "A"
        elif test_score >= 80 and test_score < 90:
            return "B"
        elif test_score >= 70 and test_score < 80:
            return "C"
        elif test_score >= 60 and test_score < 70:
            return "D"
        else:
            return "F"
def caluculate_avg(scores):
    all_grades = 0
    for i in range(len(scores)):
        all_grades = all_grades + scores[i]
    return all_grades / float(len(scores))

for c in range(6):
    scores = []
    student_name =  input("Please enter the student\'s name: ")
    for x in range(6):
        test_score = int(input("Please enter test scores: "))
        scores.append(test_score)
    scores_averaged = calculate_avg(scores)
    print("Student: ", students_name)
    for z in range(len(scores)):
        print("Test Score: ", scores[z], "Test Letter Grade: ", calcualte_letter_grades(scores[z]))
    print("Average test score: ", scores_averaged)

我得到的錯誤是：

"NameError: name 'calculate_avg' is not defined"

我不明白為什么，我以為我已經定義了它。

Answer 1

我想你錯過了“計算”這個詞

def caluculate_avg(scores):

改成

def calculate_avg(scores):

Answer 2

function 名稱拼寫錯誤“計算”。

Answer 3

您的 function 名稱是caluculate_avg但您調用calculate_avg
所以這只是一個錯字問題並更改此行

def caluculate_avg(scores):

對此

def calculate_avg(scores):

Answer 4

因為 function 名稱和呼叫中有錯字。 你在定義

def caluculate_avg(scores):

但你正在使用

scores_averaged = calculate_avg(scores)

將 function 定義更改為

 def calculate_avg(scores):

Answer 5

您使用不同的名稱調用了 function， “calculate_avg”而不是“calculate_avg”，請確保在調用時使用相同的 function 名稱
