重命名和下载链接 - CSV 文件

Question

I have a CSV file with 6 columns and many rows. I would like to download all the png or jpg from the column 'link' in a folder with the same name of my CSV file.Then I would like to rename these images with each 'title' content.

url1.png by name1.png for each files and until the last row..

I started something with this -

import csv
with open('name.csv') as csvfile:
    reader = csv.reader(csvfile, delimiter=',', quotechar='|')
    for row in reader:
        fileurl = row[0]
        filename = row[1]
        urllib.request.urlretrieve(fileurl, "name" + filename)

Rows example -

Still learning.. Any help or suggestions to do this?

Many thanks.

If I understand you correctly, you would like to download the file in the link column using the title column to form the filename.

This can be done as follows:

import urllib.request
import csv
import os

with open('name.csv') as csvfile:
    reader = csv.DictReader(csvfile)
    
    for row in reader:
        name, ext = os.path.splitext(row['link'])
        title_filename = f"{row['title']}{ext}".replace('/', '-')
        urllib.request.urlretrieve(row['link'], title_filename)

You can use .os.path.splitext() to split out the extension of the filename. This can then be used to combine with the entry from title to form a new filename.

For example:

https://url.com/folder/url1.png would save as name1.png

To deal with multiple identical title entries, you could investigate Python's Counter() to keep track of how many of each title you have. For example:

from collections import Counter
import urllib.request
import csv
import os

with open('name.csv') as csvfile:
    reader = csv.DictReader(csvfile)
    title_counts = Counter()
    
    for row in reader:
        name, ext = os.path.splitext(row['link'])
        title = row['title']
        title_counts[title] += 1
        title_filename = f"{title}_{title_counts[title]}{ext}"
        urllib.request.urlretrieve(row['link'], title_filename)
