告訴我這個功能有什麼問題嗎？

Question

def compute_invigilated_mark(): 

    """Prints given name and family name with overall score""" 

    test = 0.15 

    exam = 0.60  

    first_name = input("Given names(s)? ") 

    last_name = input("Family name? ") 

    both_names = last_name.upper() + "," + first_name.title() 

    new_test_percent = float(input("Test percent? ")) * test 

    new_exam_percent = float(input("Exam percent? ")) * exam 

    overall_percent = new_test_percent + new_exam_percent 

    end_result = overall_percent/(exam + test) 

    print(both_names + end_result) 

compute_invigilated_mark() 

我想要得到的最終結果，例如：Bourne, Jason: 66.0

的rrror消息：

builtins.TypeError: Can't convert 'float' object to str implicitly.

注：我昏昏沉沉地出來這樣的，所以你可以閱讀更容易:)。

Answer 1

both_names是一個字符串，而end_result是一個浮點數，但是您試圖將它們連接在一起（print(both_names + end_result)）。

你應該end_result轉換爲字符串：

print(both_names + str(end_result))
