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)
