如果可能,请指出解决方案

我的代码:

import random
import urllib.request

def download_web_image(url):
name = random.randrange(1,1000)
fullname = str(name) + ".jpg"
urllib.request.urlretrieve(url, fullname)

download_web_image("https://upload.wikimedia.org/wikipedia/commons/b/b4/JPEG_example_JPG_RIP_100.jpg")

错误:

During handling of the above exception, another exception occurred:

最佳答案

试试这个对我有用:

import random
import urllib.request

def download_web_image(url):
name = random.randrange(1,1000)
fullname = str(name) + ".jpg"
urllib.request.urlretrieve(url, fullname)

print(download_web_image("https://upload.wikimedia.org/wikipedia/commons/b/b4/JPEG_example_JPG_RIP_100.jpg"))

输出:None 但没问题!

文件保存在与脚本相同的目录中。
