Necessary packages for downloading files using Python

In Python, the following packages are required to download files:

• Requests: Used to send HTTP requests
• urllib.request: Used to process URL requests
• os: Used to Create and manipulate files

Steps to download files

The steps to download files using Python are as follows:

import requests import os # 设置下载 URL url = "https://example.com/file.txt" # 发送 HTTP 请求并获取响应 response = requests.get(url) # 检查响应状态代码是否为 200 (成功) if response.status_code == 200: # 获取文件名 filename = os.path.basename(url) # 打开一个文件用于写入 with open(filename, "wb") as file: # 将响应内容写入文件 file.write(response.content)

Example

The following code snippet demonstrates how to download a file from a URL using Python:

import requests import os url = "https://example.com/file.txt" response = requests.get(url) if response.status_code == 200: filename = os.path.basename(url) with open(filename, "wb") as file: file.write(response.content)

Other considerations

• Authentication :If the download target URL requires authentication, you need to provide credentials using theauthparameter inrequests.
• Timeout:You can use thetimeoutparameter in therequests.get()function to set the request timeout.
• Streaming download:For large files, you can use thestream=Trueparameter in therequests.get()function for streaming downloading , to read the file chunk by chunk rather than downloading the entire file into memory at once.
