第一欄為姓名(name)，第二欄為年紀(age)，第三欄為得分(score)

現在，寫一個Python程式，

1）讀取檔案

2）列印如下結果：

得分低於60的人都有誰？

誰的名字以L開頭？

所有人的總分是多少?

3）姓名的首字母需要大寫，該record.txt是否符合此要求？ 如何糾正錯誤的地方？

#read lines from filefobj = open('record.txt', 'r+')print 'opened file: ', fobj.nameall_lines = fobj.readlines()fobj.close()lines = [l[:-1].split(', ') for l in all_lines if not l.startswith('#') and l.strip()]#list person who's score less than 60print [s[0] for s in lines if int(s[2]) < 60]#list person who's name starts with 'L'print [s[0] for s in lines if s[0].startswith('L')]#compute the score of all personprint sum([int(s[2]) for s in lines])#write new lines contains capitalize name into filefobj = open('record2.txt', 'w+')print 'opend file: ', fobj.namenewlines = []for line in all_lines:    if line[0].islower():        line = line.capitalize()    newlines.append(line)print newlinesif newlines:    fobj.writelines(newlines)fobj.close()
