python计算学生总成绩

假设你有一个包含学生姓名、语文成绩、数学成绩、英语成绩的字典列表，可以使用以下代码计算每个学生的总成绩：

students = [
    {"name": "Alice", "chinese": 90, "math": 85, "english": 95},
    {"name": "Bob", "chinese": 80, "math": 90, "english": 85},
    {"name": "Charlie", "chinese": 95, "math": 95, "english": 90},
]

for student in students:
    total = student["chinese"] + student["math"] + student["english"]
    print(f"{student['name']}'s total score is {total}")

输出结果为：

Alice's total score is 270
Bob's total score is 255
Charlie's total score is 280

你也可以将每个学生的总成绩保存在原始字典中，例如：

for student in students:
    student["total"] = student["chinese"] + student["math"] + student["english"]
    print(f"{student['name']}'s total score is {student['total']}")

这样每个学生的字典会变成：

{"name": "Alice", "chinese": 90, "math": 85, "english": 95, "total": 270}
