download files via FTP

Question

This is my code,I have used aioftp and asyncio with no success

import asyncio
import requests
import aiohttp
import urllib.request
import urllib.error
import time
import urllib.request

t1 = time.time()


async def job(session,url):
    filename = url.split("/")[-1]
    ftp = await session.get(url)
    ftpcode = await ftp.read()
    with open("new/"+str(filename),'wb') as f:
        f.write(ftpcode)
    return str(url)

    # urllib.request.urlretrieve(url, filename)

async def main(loop,URL):
    async with aiohttp.ClientSession()as session:
        tasks = [loop.create_task(job(session, URL[x])) for x in range(2)]
   
        finished, unfinished = await asyncio.wait(tasks)
        all_results = [r.result() for r in finished]
        print("ALL RESULT:", all_results)


URL = ["ftp://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_package/8e/71/PMC5334499.tar.gz",
"ftp://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_package/ad/b5/PMC7444942.tar.gz",
"ftp://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_package/e8/38/PMC8903393.tar.gz",
"ftp://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_package/f3/7d/PMC9130726.tar.gz"]

loop = asyncio.get_event_loop()
loop.run_until_complete(main(loop,URL))
loop.close()

t2 = time.time()
print(int(t2-t1))

If you can help, I would be very grateful
