我遇到了一个 zyBooks 问题。
以下程序根据三个同等权重的考试计算课程的总成绩。
然后提供这个代码：
exam1_grade = float(input('Enter score on Exam 1 (out of 100):\n'))
exam2_grade = float(input('Enter score on Exam 2 (out of 100):\n'))
exam3_grade = float(input('Enter score on Exam 3 (out of 100):\n'))
overall_grade = (exam1_grade + exam2_grade + exam3_grade) / 3
print('Your overall grade is:', overall_grade)
然后这些问题。
计算四项同等权重的编程作业的总分，每项作业满分 50 分。提示：首先计算每项作业的百分比（例如分数/50），然后计算总成绩百分比（一定要将结果乘以 100）。
计算四个同等权重的编程作业的总成绩，其中作业 1 和 2 的评分为 50 分，作业 3 和 4 的评分为 75 分。
计算一门课程的总成绩，其中三门等权重考试（满分 100 分）占总成绩的 60%，四门等权重编程作业（满分 50 分）占总成绩的 40%。提示：总成绩可以计算为 0.6 * averageExamScore + 0.4 * averageProgScore。
我（相信）我有前两个问题，但我卡在了最后一个问题上。输入应该得到 100 分的输入，我得到 2.7，所以它给我的结果太低了。谁能帮我弄清楚我做错了什么？
