用Python批量实现文件夹下所有txt行数据的分段排序

问题描述：

烦请各位老师支持！感谢

1、文件夹下有多个TXT文件，文件内容全部为整数（共有7列，数字间以逗号相隔）；

2、删除每行后两列数字相等的行

3、通过Python实现每行前5列按从小到大排序，后两列也从小到大排序（每行前5列数字不重复，后两列数字相等的已删除）；

4、排列完成后，将重新排列的TXT也存在原文件夹下，原TXT删除。

import os
def show_files(path, all_files):
    file_list = os.listdir(path)
    for file in file_list:
        cur_path = os.path.join(path,file)
        if os.path.isdir(cur_path):
            show_files(cur_path, all_files)
        else:
            all_files.append(file)
    return all_files
contents = show_files(r'D:/test/', [])
# 循环打印show_files函数返回的文件名列表

for i in contents:
    n = 0
    n2 = 0
    b=[]
    d1=[]
    list1 = []
    with open(r'D:/test/'+i,encoding='utf-8') as f:
        data = f.read().splitlines()
        for ll in range(len(data)):
            list1.append(data[ll].split(","))
        for j in list1:
            for k in j:
                if k != '':
                    d1.append(int(k))
        for l in range(int(len(d1)/7)):
            n = n + 7
            #给每行的前5位排序
            line_q5 = d1[n2:n][0:5]
            line_q5.sort()
            #给每行的后2位排序
            line_h2 = d1[n2:n][-2:]
            line_h2.sort()
            if d1[n2:n][5] != d1[n2:n][6]:  #后两位相等则删除此行
                b.append(line_q5+line_h2)
            n2 = n2 + 7

    with open(r'D:/test/' + i,"w", encoding='utf-8') as f:
        for b2 in b:
            for value in b2:
                f.write(str(value)+'，')
            f.write('\n')

答

import os
name=['a']
for i in name:
	b=[]
	c=[]
	with open('{0}.txt'.format(i),'r',encoding='utf-8') as f:
		for line in f:
			alist=line.split('，')
			anewlist=[int(x.strip()) for x in alist]
			if anewlist[-1]==anewlist[-2]:
				continue
			else:
				b.append(anewlist)
	with open('{0}new.txt'.format(i),'w',encoding='utf-8') as f:
		for n in b:
			d=sorted(n[:5])+sorted(n[5:])
			for m in d:
				f.write(str(m)+'，')
			f.write('\n')
	os.remove('{0}.txt'.format(i))
