处理范围检查和列表的 Python 3 float 错误

Question

我正在上我的第一门 Python 类(class)。对于我们的作业，我们应该收集 6 个等级，检查它们是否在 0-100 的范围内，如果它们找到平均值，如果不是则给出错误消息。然后我们应该询问他们的总成绩并做同样的事情。因此，我实际上已经为第二部分复制了一部分代码(正在运行)，但现在我遇到了类型调用错误，我不知道为什么。你们能帮我弄清楚我哪里出错了，并指出正确的方向吗？这是我的代码:

six_grade_list = []
print("Please enter six grades using a comma to separate them to get your average.")
six_grade_list = [float(i) for i in input().split(',')]
for float in six_grade_list:
    if 0<= float <= 100:
        print("Your average is ", sum(six_grade_list)/len(six_grade_list))
        break
    else:
        print("One of the grades you entered is not between 0 and 100.")
        break
total_grade_list = []
print("This time please enter all of your grades using a comma to separate them to get your average.")
total_grade_list = [float(i) for i in input().split(',')]
for float in total_grade_list:
    if 0<= float <= 100:
        print("Your average is ", sum(total_grade_list)/len(total_grade_list))
        break
    else:
        print("One of the grades you entered is not between 0 and 100.")
        break

我得到的错误:

Traceback (most recent call last):
  File "C:/Users/jesse/PycharmProjects/untitled/CYBR-260-40A/Week2AlternativeAssignment.py", line 13, in <module>
    total_grade_list = [float(i) for i in input().split(',')]
  File "C:/Users/jesse/PycharmProjects/untitled/CYBR-260-40A/Week2AlternativeAssignment.py", line 13, in <listcomp>
    total_grade_list = [float(i) for i in input().split(',')]
TypeError: 'float' object is not callable

提前致谢。

您在 for 循环中使用 float 变量覆盖了 float 函数。将 float 变量重命名为其他名称，您的代码就可以工作了:

print("Please enter six grades using a comma to separate them to get your average.")
six_grade_list = [float(i) for i in input().split(',')]
for grade in six_grade_list:
    if 0<= grade <= 100:
        print("Your average is ", sum(six_grade_list)/len(six_grade_list))
        break
    else:
        print("One of the grades you entered is not between 0 and 100.")
        break
print("This time please enter all of your grades using a comma to separate them to get your average.")
total_grade_list = [float(i) for i in input().split(',')]
for grade in total_grade_list:
    if 0<= grade <= 100:
        print("Your average is ", sum(total_grade_list)/len(total_grade_list))
        break
    else:
        print("One of the grades you entered is not between 0 and 100.")
        break
