每天進步一點點--------python之計算平均分__python

周末的圖書館真是太熱鬧了，好多小孩子圍在一起做作業讓我想起以前讀書的時候也是這樣。剛好這個課後練習就是計算成績的平均分，想來當初老師如果有這玩意應該會輕鬆很多吧，畢竟一個一個算實在是有夠麻煩的。不是很複雜的小指令碼，不過很實用。

lloyd = {    "name": "Lloyd",    "homework": [90.0, 97.0, 75.0, 92.0],    "quizzes": [88.0, 40.0, 94.0],    "tests": [75.0, 90.0]}alice = {    "name": "Alice",    "homework": [100.0, 92.0, 98.0, 100.0],    "quizzes": [82.0, 83.0, 91.0],    "tests": [89.0, 97.0]}tyler = {    "name": "Tyler",    "homework": [0.0, 87.0, 75.0, 22.0],    "quizzes": [0.0, 75.0, 78.0],    "tests": [100.0, 100.0]}students = [lloyd,alice,tyler]def average (lst):                             #計算平均值，精確到小數點    return float(sum(lst))/len(lst)    def get_average(student):                      #按照不同的比例計算平比分，大學經常這樣弄    homework = student['homework']    quiz = student['quizzes']    test = student['tests']    return average(homework)*0.1 +average(quiz)*0.3 + average(test)*0.6    def get_letter_grade(score):                   #按照分數排等級    if score >= 90:        return "A"    elif score >= 80 and score < 90:        return "B"    elif score >= 70 and score < 80:        return "C"    elif score >= 60 and score < 70:        return "D"    else :        return "F"         def get_class_average(class_list):             #計算全班的平均分，先用迴圈計算出總分然後除去人數    total = 0    for i in class_list:        total += get_average(i)    return total/len(class_list)

等基本的知識牢固之後再就是邏輯思維的考驗了，革命尚未成功，同志仍需努力。
