python实现将多个文件分配到多个文件夹的方法


						如下所示：





import os

import shutil



#path of imgr

path = 'D:\\BaiduNetdiskDownload\\newim\\'



#path of folder

folderPath = 'D:\\BaiduNetdiskDownload\\folderSort\\'



peopleNumber = 61

#new 61 folder numbers as sort_folder_number[61]

sort_folder_number = [x for x in range(0,peopleNumber)]



# makedir 61 folders

'''

demo功能说明：

在folderPath处新建60个文件夹，

图片存储在path处

给每个文件夹分配150张图片（将9000张图片平均分配到60个文件夹）



Tips:

1: os.path.join(path1,path2...)

this function is used to combine the path,it returns a path which is 'path1/path2...'



2: os.makedirs(path)

this function is used to make a directory(new folder) in the path param



3: shutil.move(oldPath,newPath)

this function is used to move file from param1 to param 2



4: os.path.exists(path)

this function is used to check the filePath(param1) whether exists

'''

for number in sort_folder_number:

 new_folder_path = os.path.join(folderPath,'%s'%number)#new_folder_path is ‘folderPath\number'



 if not os.path.exists(new_folder_path):

  os.makedirs(new_folder_path)

  print("new a floder named "+str(number)+'at the path of '+ new_folder_path)



#give the img list

file_list = os.listdir(path)



'''define the first foloderNumber'''

folderNumber = 1

print('there are '+str(len(file_list))+' files at the path of '+path)

for i in range(0,len(file_list)):

 old_file_path = os.path.join(path,str(i)+'.jpg')

 if os.path.isdir(old_file_path):

  '''if the path is a folder,program will pass it'''

  print('img does not exist ,path=' + old_file_path+' it is a dir' )

  pass

 elif not os.path.exists(old_file_path):

  '''if the path does not exist,program will pass it'''

  print('img does not exist ,path='+old_file_path)

  pass

 else:

  '''define the number,it decides how many imgs each people process'''

  number = 150 #int(len(file_list)/peopleNumber)

  if(i%number ==0):

   folderNumber +=1

  new_file_path = os.path.join(folderPath,'%s'%(folderNumber))

  if not os.path.exists(new_file_path):

   print('not exist path:'+new_file_path)

   break

  shutil.move(old_file_path,new_file_path)

  print('success move file from '+ old_file_path +' to '+new_file_path)
