[已解决]请教排序问题

Block111

需要按照最后一列排序；怎么只排序四位数的几项，后面都不能排序；
#排序
[b]def select_sort(array):
    p=list(open(array+'.txt','r'))   
    t_array=[]
    for each in p:
        l=int(each.split(',',4)[4])
        t_array.append(each)      
    for i in range(len(t_array)-1):
        min = int(i)
        for j in range(i+1, len(t_array)):
            if t_array[j] < t_array[min]:
                 min = int(t_array[j])
        p[i], p[min] = p[min], p[i]
    file=open(array+'x.txt','w')
    file.writelines(p)
    file.close()
