1. 建立新資料夾

若存在且不為空，刪除舊資料夾，重新建立

# coding=utf-8

import glob
import shutil
import os

def PicPath(path):
    if os.path.exists(path):
        print(path, " is exists!")
        if not os.listdir(path):
            print(path, " is empty!")
        else:
            print
 
(path, " is not empty ")
            shutil.rmtree(path, True)
            print("old path delete successfully")
            os.makedirs(path)
            print("new image path is Recreated successfully!")
    else:
        print(path, " is not exists!")
        os.
 
makedirs(path)
        print("new image path is created successfully!")

2.獲取指定檔案下的檔案和數量

def image_select(path):
    image_file = []
    for filename in os.listdir(path):
        image_file.append(os.path.join(path, filename))
    file_number = len(image_file)  # 指定檔案下的檔案個數
    return image_file,
 
file_number

3.移動資料夾下的指定型別檔案

def backup(srcfile, dst_dir):
    if not os.path.exists(dst_dir):
        os.makedirs(dst_dir)
        print('資料夾建立完成 ' + dst_dir)
    src_file_list = glob.glob(srcfile+ '*.*') # glob獲得路徑下所有檔案，可根據需要修改
    print (src_file_list)
    for srcfile in src_file_list:
    	shutil.move(srcfile, dst_dir)  # 移動檔案
        print ("move %s -> %s" % (srcfile, dstpath+'/'+fname))
