如果我有小明、小红和小亮三名学生的语文、数学和英语成绩数据，如何只使用Python中的字典结构和for循环来存储他们的姓名、科目和分数，并可以查询学生对应的科目分数和总分，以及谁的总分更高

你可以使用Python字典列表来存储这种信息，每个字典代表一名学生，包含姓名、三个科目的分数。这里是一个简单的例子：

# 定义一个空的字典列表来存储学生信息
students = []

# 添加小明的信息
student_ming = {"name": "小明", "scores": {"语文": 90, "数学": 85, "英语": 95}}
students.append(student_ming)

# 同理添加小红和小亮的信息
student_hong = {"name": "小红", "scores": {"语文": 95, "数学": 90, "英语": 92}}
students.append(student_hong)

student_liang = {"name": "小亮", "scores": {"语文": 92, "数学": 93, "英语": 94}}
students.append(student_liang)

# 查询函数，通过名字获取成绩
def get_score(name, subject):
    for student in students:
        if student["name"] == name:
            return student["scores"].get(subject, "未知")
    return "未找到该学生"

# 计算总分
def calculate_total_score(student):
    return sum(student["scores"].values())

# 比较总分
def find_student_with_highest_total():
    max_total = students[0]["scores"]["语文"]
    highest_student = students[0]
    
    for student in students:
        total = calculate_total_score(student)
        if total > max_total:
            max_total = total
            highest_student = student
            
    return highest_student

# 示例
print(f"小明的英语成绩是：{get_score('小明', '英语')}")
print(f"小红的总分是：{calculate_total_score(find_student_with_highest_total())}")
