python计算绩点pta

好的，关于计算绩点和 PTA，你可以参考以下 Python 代码：

# 课程成绩和学分
grades = {"Database": 90, "Web Development": 85, "Data Mining": 93, "Business Intelligence": 88}
credits = {"Database": 3, "Web Development": 4, "Data Mining": 3, "Business Intelligence": 4}

# 计算每门课的绩点和总学分
total_credits = 0
total_gpa = 0
for course, grade in grades.items():
    if grade >= 90:
        gpa = 4.0
    elif grade >= 80:
        gpa = 3.0
    elif grade >= 70:
        gpa = 2.0
    elif grade >= 60:
        gpa = 1.0
    else:
        gpa = 0.0
    credit = credits[course]
    total_gpa += gpa * credit
    total_credits += credit

# 计算绩点平均值
gpa_avg = total_gpa / total_credits
print("绩点为:", gpa_avg)

# 计算 PTA得分
pta = gpa_avg * 10 - 30
print("PTA得分为:", pta)

希望能对你有所帮助。
