如何循环遍历行值以仅返回特定值？

# 假设有一个包含学生姓名和分数的字典列表
students = [
    {"name": "Alice", "score": 85},
    {"name": "Bob", "score": 92},
    {"name": "Charlie", "score": 78},
    {"name": "David", "score": 90}
]

# 创建一个空列表来存储分数大于等于90的学生姓名
high_scores = []

# 遍历每个学生字典
for student in students:
    # 检查分数是否大于等于90
    if student["score"] >= 90:
        # 如果是，将学生姓名添加到高分列表中
        high_scores.append(student["name"])

# 打印高分学生的姓名
print(high_scores)
