python 复制文件到指定文件夹_使用python os模块复制文件到指定文件夹的方法

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')
