编写一段计算期末四门课总成绩和平均分的代码

当然可以，假设我们有一个简单的结构体或类`Course`表示一门课程，包含名称`name`和分数`score`，并且已经有一个数组或列表`courses`存储了四门课程的数据。这里是一个用Python编写的基本示例：

class Course:
    def __init__(self, name, score):
        self.name = name
        self.score = score

def calculate_total_score(courses):
    total_score = sum(course.score for course in courses)
    return total_score

def calculate_average_score(courses):
    total_score = calculate_total_score(courses)
    if len(courses) > 0:
        average_score = total_score / len(courses)
        return round(average_score, 2)  # 四舍五入到小数点后两位
    else:
        return "No courses available"

# 创建四门课程实例
courses = [Course("语文", 85), Course("数学", 92), Course("英语", 88), Course("物理", 95)]

# 计算总成绩和平均分
total = calculate_total_score(courses)
avg = calculate_average_score(courses)

print(f"四门课程总成绩为：{total}")
print(f"平均分为：{avg}")
