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
Copy after login

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)
Copy after login

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')
Copy after login

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)
Copy after login

5. Open the file

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

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

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)
Copy after login

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.

Is there a mobile app that can convert XML into PDF? Is there a mobile app that can convert XML into PDF? Apr 02, 2025 pm 09:45 PM

There is no APP that can convert all XML files into PDFs because the XML structure is flexible and diverse. The core of XML to PDF is to convert the data structure into a page layout, which requires parsing XML and generating PDF. Common methods include parsing XML using Python libraries such as ElementTree and generating PDFs using ReportLab library. For complex XML, it may be necessary to use XSLT transformation structures. When optimizing performance, consider using multithreaded or multiprocesses and select the appropriate library.

XML beautification is essentially improving its readability, including reasonable indentation, line breaks and tag organization. The principle is to traverse the XML tree, add indentation according to the level, and handle empty tags and tags containing text. Python's xml.etree.ElementTree library provides a convenient pretty_xml() function that can implement the above beautification process.

Is the conversion speed fast when converting XML to PDF on mobile phone? Is the conversion speed fast when converting XML to PDF on mobile phone? Apr 02, 2025 pm 10:09 PM

The speed of mobile XML to PDF depends on the following factors: the complexity of XML structure.

Overall, there is no absolute answer and it needs to be optimized according to the specific situation.

How to control the size of XML converted to images? How to control the size of XML converted to images? Apr 02, 2025 pm 07:24 PM

To generate images through XML, you need to use graph libraries (such as Pillow and JFreeChart) as bridges to generate images based on metadata (size, color) in XML. The key to controlling the size of the image is to adjust the values ​​of the <width> and <height> tags in XML. However, in practical applications, the complexity of XML structure, the fineness of graph drawing, the speed of image generation and memory consumption, and the selection of image formats all have an impact on the generated image size. Therefore, it is necessary to have a deep understanding of XML structure, proficient in the graphics library, and consider factors such as optimization algorithms and image format selection.
