python加权平均绩点计算

在Python中，计算加权平均绩点（Weighted Grade Point Average，简称W-GPA）通常涉及到两个关键步骤：首先，你需要有每个课程的成绩（通常是百分制分数）及其对应的绩点值；其次，需要知道每个课程的学分数。如果你有一个字典，其中键是课程名，值是元组包含成绩和学分，你可以编写一个简单的函数来计算加权平均。

def calculate_weighted_gpa(grade_dict, credit_dict):
    total_grade_points = 0
    total_credits = 0

    for course, (grade, credit) in grade_dict.items():
        if grade is not None and credit is not None:
            gpa_score = grade * credit / 100  # 计算单门课绩点
            total_grade_points += gpa_score
            total_credits += credit

    weighted_gpa = total_grade_points / total_credits if total_credits > 0 else 0
    return weighted_gpa

# 示例数据
grades = {'数学': (95, 4), '英语': (88, 3), '物理': (90, 3)}
credits = {'数学': 4, '英语': 3, '物理': 3}

weighted_avg = calculate_weighted_gpa(grades, credits)
print(f"加权平均绩点: {weighted_avg}")
