python面试题

# name, age, score
tom, 12, 86
Lee, 15, 99
Lucy, 11, 58
Joseph, 19, 56

第一栏为姓名(name)，第二栏为年纪(age)，第三栏为得分(score)

现在，写一个Python程序，

1）读取文件

2）打印如下结果：

得分低于60的人都有谁？

谁的名字以L开头？

所有人的总分是多少?

3）姓名的首字母需要大写，该record.txt是否符合此要求？ 如何纠正错误的地方？

#read lines from file
fobj = open('record.txt', 'r+')
print 'opened file: ', fobj.name
all_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 60
print [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 person
print sum([int(s[2]) for s in lines])
#write new lines contains capitalize name into file
fobj = open('record2.txt', 'w+')
print 'opend file: ', fobj.name
newlines = []
for line in all_lines:
    if line[0].islower():
        line = line.capitalize()
    newlines.append(line)
print newlines
if newlines:
    fobj.writelines(newlines)
fobj.close()
