我有以下代码抛出和错误。

Question

# This program records the names of 12 students in a list
# named students.
NUM_STUDENTS = 12

def main():
    # Create a list to hold the names of students.
    students = [0] * NUM_STUDENTS

    # Create a variable to hold an index
    index = 0

    print('Enter the names of 12 students.')

    # Add student names to the list.
    while index < NUM_STUDENTS:
        # Get the name of a student from the user.
        students[index] = input('Enter the name of a student: ')
        index += 1

        # Append a name to the student list.
        students.append(students)

排序时出错？ 我该如何解决？ 第24行，在主要students.sort（）中TypeError：不可排序的类型：list（）<str（）

    # Sort the list of name alphabetically.
    students.sort()
    print('Alphabetically sorted list of names:', students)

    # Reverse the list of names
    students.reverse()
    print('Reverse sorted list of name:', students)

Answer 1

问题在于这一行： students.append(students) 。 这会将当前的students列表添加到其末尾，在这种情况下这没有任何意义。 如果要解决此问题，请删除该行。
