使⽤pythonos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 = place('.','')
old_name = old_path + '\\' + i
new_name = new_path + '\\' + name + ".json"
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')
numpy库运行速度
name = place('.', '')
old_name = old_path + '\\' + i
new_name = new_path + '\\' + name + ".json"
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')
