我如何从列表中的多个 url 下载图像

Question

如何从 pandas 数据框中的列表中的多个 url 下载所有图像。我是python新手。

# for a single url, i can download the image:

url = ['http://pbs.twimg.com/media/EPFVkqcWkAYTDVi.jpg'] 

import wget
for photos in url:
    wget.download(photos)

# But i have multiple url in the list. 

url = ['http://pbs.twimg.com/media/EPFVkqcWkAYTDVi.jpg,http://pbs.twimg.com/media/EPFVkqcWkAYTDVi.jpg,http://pbs.twimg.com/media/EPFVkqcWkAYTDVi.jpg'] 

# i get error trying to download all the images
**Exception: 404: Not Found**

# I also want the download to skip any invalid url and continue.

分别引用每个 url 并使用 Try\Except 以防出错：

试试这个代码：

url = ['https://images.wallpaperscraft.com/image/pier_sea_horizon_189419_168x300.jpg',
       'https://images.wallpaperscraft.com/image/paint_liquid_fluid_art_189413_168x300.jpg',
       'https://images.wallpaperscraft.com/image/sunset_glare_city_189428_168x300.jpg',
       'https://images.wallpaperscraft.com/image/maple_leaf_macro_189405_168x300.jpg']
        
import wget
import time  # for sleep

for photos in url:
    try: 
       print('\nGet:', photos)   
       wget.download(photos)
       time.sleep(1)  # pause 1 second, if needed
    except Exception as ex:
       print('Failed to get:',photos, ex)
