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')
