python 读取指定文件夹下的所有图片再输出指定内容到TXT文件中

import sys
import os

paths=['MOTFish/train/Black-porgy/img1']

f=open('MOTFish.txt', 'w')
for path in paths:
    sh_path=os.path.abspath(path)
    #sh_path = os.path.dirname(os.path.abspath(sys.argv[0]))
    sh_path = '/'.join(sh_path.split('\\'))#将 \ 替换成 /
    print("sh_path",sh_path)
    filenames=os.listdir(sh_path)
    for filename in filenames:
        im_path=sh_path+'/'+filename
        print(im_path)
        f.write(im_path+'\n')
f.close()

删除指定内容

import sys
import os

import ss as ss

paths=['MOTFish/train/Black-porgy/img1']

f=open('MOTFish.txt', 'w')
for path in paths:
    sh_path=os.path.abspath(path)
    #sh_path = os.path.dirname(os.path.abspath(sys.argv[0]))
    sh_path = '/'.join(sh_path.split('\\'))#将 \ 替换成 /

    print("sh_path",sh_path)
    filenames=os.listdir(sh_path)

    for filename in filenames:
        im_path=sh_path+'/'+filename

        print(im_path)

        i_path=im_path.replace("D:/Project/fish_data/code/paddle/PaddleDetection-release-2.3/","")

        print(i_path)

        f.write(i_path+'\n')
f.close()

感觉不是按顺序读取的，添加一个排序

import sys
import os

paths=['MOTFish/train/Black-porgy/img1']

f=open('MOTFish.txt', 'w')
for path in paths:
    new_path=os.path.abspath(path)
    new_path = '/'.join(new_path.split('\\'))#将 \ 替换成 /
    new_path = new_path.replace("D:/Project/fish_data/code/paddle/PaddleDetection-release-2.3/", "")
    print("sh_path",new_path)

    filenames=os.listdir(new_path)
    filenames.sort(key=lambda x: int(x.split('.')[0]))#排序
    print("filenames",filenames)

    for filename in filenames:
        path2=new_path+'/'+filename
        print(path2)
        f.write(path2+'\n')
f.close()

 输出的内容正好是我想要的
