How to open Python after downloading

Downloading and opening the file using Python involves the following steps: Import the requests library. Use the requests.get() method to send an HTTP GET request. Check the HTTP status code (200 indicates success). Write the downloaded file contents to a local file. Open the downloaded file using the open() function.

Downloading a file and opening it using Python

Downloading a file and opening it using Python is relatively simple. Here is a step-by-step guide to accomplish this task:

1. Import the necessary libraries

First, you need to import the requests library, which uses To send HTTP requests and download files.

import requests

2. Send an HTTP request

Use the requests.get() method to send an HTTP GET request to download the file. This method receives the file URL as parameter.

url = 'https://example.com/file.txt'
response = requests.get(url)

3. Check the status code

HTTP status code indicates whether the request was successful. 200 indicates successful download.

if response.status_code == 200:
    print('文件下载成功')
else:
    print('文件下载失败')

4. Write the file

Write the contents of the downloaded file to the local file.

with open('file.txt', 'wb') as f:
    f.write(response.content)

5. Open the file

Use the open() function to open the downloaded file.

with open('file.txt', 'r') as f:
    content = f.read()

Practical case: Download text file

import requests

url = 'https://raw.githubusercontent.com/learnpython/sample-code/master/exercises/file.txt'

response = requests.get(url)

if response.status_code == 200:
    with open('downloaded_file.txt', 'wb') as f:
        f.write(response.content)

    with open('downloaded_file.txt', 'r') as f:
        content = f.read()
        print(content)

This code will download a text file from the specified URL and write it into a file named downloaded_file.txt local file and print its contents.
