从列表下载文件（如果尚未下载）

尽管我认为

urls.txt

文件仅包含url ，但这应该可以解决问题。不是

url:

前缀。

import osimport urllibDOWNLOADS_DIR = '/python-downloader/downloaded'# For every line in the filefor url in open('urls.txt'):    # Split on the rightmost / and take everything on the right side of that    name = url.rsplit('/', 1)[-1]    # Combine the name and the downloads directory to get the local filename    filename = os.path.join(DOWNLOADS_DIR, name)    # Download the file if it does not exist    if not os.path.isfile(filename):        urllib.urlretrieve(url, filename)
