Print(e) Download ZIP files, PDF files, etc. urlopen(url) as web_file, open(dst_path, 'wb') as local_file: Compound statements - The with statement - Python 3.10.0 Documentation Nested with statements can be written at once, separated by commas. Open() with mode='wb' as the second argument writes the data as binary. The data that can be obtained with () is a byte string (bytes type). It is also possible to use the third-party library Requests instead of the standard library urllib to open the url and get the data. If you want to also catch exceptions (FileNotFoundError, etc.) when saving locally, do the following. urllib.error - Exception classes raised by urllib.request - Python 3.10.0 Documentation.The error message will be displayed when the URL of the file does not exist.
In the example, urllib.error is imported and only is explicitly captured. To avoid stopping when an exception occurs, catch the error with try and except. urllib.request - Extensible library for opening URLs - Python 3.10.0 Documentation.() has not been deprecated yet, but may be in the future. Note that urllib.urlopen() has been deprecated in Python 2.6 and earlier. Use () to open the URL and retrieve the data. The following sections describe the part of the data acquisition and the part of the data saving as a file. It extracts the file name from the URL with os.path.basename() and joins it with the directory specified with os.path.join() to generate the destination path. To specify the destination directory and save the file with the URL file name, do the following def download_file_to_dir(url, dst_dir):ĭownload_file(url, os. With open(dst_path, mode = 'wb') as local_file: import os import pprint import time import urllib.error import urllib.request def download_file(url, dst_path): This code is a bit verbose for the sake of explanation. The following is an example of a function that downloads and saves a file by specifying the URL and destination path, and its usage. You can use the standard library only to download individual files by specifying their URLs no additional installation is required. Batch download multiple images from a list of URLs.Extract the URL of the image on the web page.Write to a file in binary mode in open().
