本文实例为大家分享了python批量处理文件或文件夹的具体代码，供大家参考，具体内容如下

# -*- coding: utf-8 -*-
import os,shutil
import sys
import numpy as np
##########批量删除不同文件夹下的同名文件夹#############
def arrange_file(dir_path0):
  for dirpath,dirnames,filenames in os.walk(dir_path0):
    if 'my_result' in dirpath:
      # print(dirpath)
      shutil.rmtree(dirpath)


##########批量在不同文件夹下新建同名子文件夹并把文件搬移到子文件夹#############
def arrange_file(dir_path0):
  for dirpath,dirnames,filenames in os.walk(dir_path0):
    for files in filenames:
      total_path = os.path.join(dirpath,files)
      root_path,file_path = total_path.split(dir_path,1)
      if 'png' in file_path:
        new_file_path = '.' + file_path[:-9] + 'new_file_name/'
        # print(file_path)
        # print(new_file_path)
        # print(new_file_path + file_path[-9:])
        # if not os.path.exists(new_file_path):
        #   os.makedirs(new_file_path)
        # shutil.move('.' + file_path,new_file_path + file_path[-9:])

##########批量删除不同文件夹下符合条件的文件##################
def arrange_file(dir_path0):
  for dirpath,dirnames,filenames in os.walk(dir_path0):
    for files in filenames:
      total_path = os.path.join(dirpath,files)
      # print(total_path)
      if 'jpg' in total_path and 'labels' in total_path:
        img = cv2.imread(total_path)
        if np.sum(img) == 0:
          print(total_path)
          os.remove(total_path)

###########批量把文件搬移到上一层文件夹并删除当前文件夹########
def arrange_file(dir_path0):
  for dirpath,dirnames,filenames in os.walk(dir_path0):
    for files in filenames:
      total_path = os.path.join(dirpath,files)
      root_path,file_path = total_path.split(dir_path0,1)
      # print(file_path[:-48])
      # return 0
      if 'jpg' in file_path:
        new_file_path = dir_path0 + file_path[:-48]
        shutil.move(dir_path0 + file_path,new_file_path + file_path[-9:])

  for dirpath,dirnames,filenames in os.walk(dir_path0):
    file_path = dirpath.split('./your_total_path')[1]
    if 'keywords' in file_path:
      # print(dirpath) 
      shutil.rmtree(dirpath)

if __name__=='__main__':
  dir_path0 = './your_total_path'
  arrange_file(dir_path0)
