假设您需要写一个应用程序来管理学生信息。给定以下学生数据，输出所有生日在9月份的学生姓名和他们的分数。
Student 1: Name: John Doe, Birthday: Aug 25, 2000, Score: 90
Student 2: Name: Jane Smith, Birthday: Sep 14, 2001, Score: 85
Student 3: Name: Bob Johnson, Birthday: Mar 10, 1999, Score: 92
Student 4: Name: Mary Lee, Birthday: Sep 5, 2002, Score: 87
以下是输出所有出生日期在9月份的学生的姓名和分数的代码：

```python
students = [
    {"name": "John Doe", "birthday": "Aug 25, 2000", "score": 90},
    {"name": "Jane Smith", "birthday": "Sep 14, 2001", "score": 85},
    {"name": "Bob Johnson", "birthday": "Mar 10, 1999", "score": 92},
    {"name": "Mary Lee", "birthday": "Sep 5, 2002", "score": 87}
]

for student in students:
    # 解析生日
    birthday_parts = student["birthday"].split(" ")
    month = birthday_parts[0]
    month = month.lower().replace(".", "")
    
    # 如果生日在9月，输出姓名和分数
    if month == "sep":
        print(f"{student['name']}: {student['score']}")
```

输出：

```
Jane Smith: 85
Mary Lee: 87
```
