使用python os模块复制文件到指定文件夹的方法

import os
import shutil
import time

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\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')

import gevent
from gevent import monkey

monkey.patch_all()
import os
import shutil
import time


def 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)
