【再回首Python之美】【文件】根据成绩表，生成每个学生总成绩表

有学生成绩表：
    一个学生一行，如Tom 98 89 76 68
总成绩表：
   一个学生一行，如Tom    :331
代码如下：
#score.py

score_file = "C:\Python27\mydata\score.txt"
sum_file = "C:\Python27\mydata\sum.txt"

def lineCount(file_path):
f = file(filepath)
lines = f.readlines()
f.close()
return len(lines)

def writeFile(file_path, data_list):
fout = file(sum_file, 'w')
fout.writelines(data_list)
fout.close()

def dumpFile(file_path):
fin = file(file_path)
lines = fin.readlines()
print lines
fin.close()

def sumList(score_file):
f = file(score_file)
lines = f.readlines()
f.close()
sum_list = [] #save every student score sum
for line in lines: #John 86 98 79 66
score_list = line.split()
total = 0 #save current student score sum
student = score_list[0] #save current student name
for score in score_list[1:]:
total += int(score)
result = '%s\t:%d\n' % (student, total)
sum_list.append(result) #append result to list tail
print sum_list
writeFile(sum_file, sum_list)
return sum_list

#test

dumpFile(score_file)
sumList(score_file)
dumpFile(sum_file)
