在Python中下载带回调的CSV

import requests
import csv

def download_csv_with_callback(url, callback):
    response = requests.get(url, stream=True)
    total_size = int(response.headers.get('content-length', 0))
    downloaded_size = 0

    with open('data.csv', 'wb') as file:
        for chunk in response.iter_content(chunk_size=1024):
            if chunk:
                file.write(chunk)
                downloaded_size += len(chunk)
                progress = downloaded_size / total_size * 100
                callback(progress)

def progress_callback(progress):
    print(f"Download progress: {progress:.2f}%")

url = 'https://example.com/data.csv'
