绿草如茵的草原上还有一条细细的河，袒露在阳光下，远远看去，像一条发光的银项链。
复制一个文件夹的文件到指定目录下
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')
优化速度：
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)
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')
以上这篇使用python os模块复制文件到指定文件夹的方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
