下面这段代码:
# name, age, scoretom, 12, 86lee, 15, 99lucy, 11, 58joseph, 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 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()
