复制一个文件夹的文件到指定目录下

import osimport shutilimport timestart_time = time.time()# 需要被复制的文件夹old_path = r'D:\zjf_workspace\001-地标、利器、服饰\004文本\json1'new_path = r'D:\zjf_workspace\001-地标、利器、服饰\004文本\json'all_list = os.listdir(old_path)for i in all_list: print(i) name, suffix = i.rsplit('.json') name = name.replace('.','') old_name = old_path + '\\' + i new_name = new_path + '\\' + name + ".json" shutil.copyfile(old_name, new_name)print(len(all_list))print(all_list)end_time = time.time()print(end_time-start_time,'秒')

优化速度：

import geventfrom gevent import monkeymonkey.patch_all()import osimport shutilimport timedef copy_file(i): global num num += 1 print(i,num) old_path = r'D:\zjf_workspace\001-地标、利器、服饰\004文本\baidu_isbn5\新建文件夹\txt' new_path = r'D:\zjf_workspace\001-地标、利器、服饰\004文本\百度isbn-json-非selenium5' name, suffix = i.split('.json') name = name.replace('.', '') old_name = old_path + '\\' + i new_name = new_path + '\\' + name + ".json" shutil.copyfile(old_name, new_name)if __name__ == '__main__': start_time = time.time() # 需要被复制的文件夹 old_path = r'D:\zjf_workspace\001-地标、利器、服饰\004文本\baidu_isbn5\新建文件夹\txt' all_list = os.listdir(old_path) gevent_list = [] num = 1 key_num = 0 for i in all_list:  key_num += 1  if key_num >= 1500:   gevent.joinall(gevent_list)   gevent.killall(gevent_list)   gevent_list = []   key_num = 0  gevent_list.append(gevent.spawn(copy_file, i))  # print(i) print(len(all_list)) # print(all_list) gevent.joinall(gevent_list) end_time = time.time() print(end_time - start_time, '秒')
