Practical Python implements conversion of BT seeds into magnet links
Practical Python implements conversion of BT seeds into magnet links
Friends who often watch movies must be familiar with BT seeds, but BT seed files are inconvenient to store compared to magnet links, and storing BT files on a website can easily cause copyright disputes, while magnet links are relatively less risky.
Converting BT seeds to magnet links that take up less space and are more convenient for sharing has great benefits.
Today we will take a look at how to convert seeds into magnet links. The solution is: use python’s bencode module, which is relatively simple to use.
First of all, you need to install this module. The installation command:
pip install bencode
If pip is not installed , please move to "Detailed explanation of python package manager pip installation"
Actual code
After the installation is completed, let's take a look at the code:
System environment: Linux
Python environment: Python2.7
Please pay attention to the python version
bt2url.py
#! /usr/local/bin/python # @desc python通过BT种子生成磁力链接 # @date 2015/11/10 # @author pythontab.com import bencode import sys import hashlib import base64 import urllib #获取参数 torrentName = sys.argv[1] #读取种子文件 torrent = open(torrentName, 'rb').read() #计算meta数据 metadata = bencode.bdecode(torrent) hashcontents = bencode.bencode(metadata['info']) digest = hashlib.sha1(hashcontents).digest() b32hash = base64.b32encode(digest) #打印 print 'magnet:?xt=urn:btih:%s' % b32hash
How to use?
Command:
python bt2url.py test.torrent
Result:
magnet:?xt=urn:btih:MWXFHXOGE2UMR7WBFZYEJPM3LF2VIHNH

Python vs. C : Applications and Use Cases Compared
Apr 12, 2025 am 12:01 AM
Python is suitable for data science, web development and automation tasks, while C is suitable for system programming, game development and embedded systems. Python is known for its simplicity and powerful ecosystem, while C is known for its high performance and underlying control capabilities.
Python: Games, GUIs, and More
Apr 13, 2025 am 12:14 AM
Python excels in gaming and GUI development. 1) Game development uses Pygame, providing drawing, audio and other functions, which are suitable for creating 2D games. 2) GUI development can choose Tkinter or PyQt. Tkinter is simple and easy to use, PyQt has rich functions and is suitable for professional development.
Python vs. C : Learning Curves and Ease of Use
Apr 19, 2025 am 12:20 AM
Python is easier to learn and use, while C is more powerful but complex. 1. Python syntax is concise and suitable for beginners. Dynamic typing and automatic memory management make it easy to use, but may cause runtime errors. 2.C provides low-level control and advanced features, suitable for high-performance applications, but has a high learning threshold and requires manual memory and type safety management.
Python and Time: Making the Most of Your Study Time
Apr 14, 2025 am 12:02 AM
To maximize the efficiency of learning Python in a limited time, you can use Python's datetime, time, and schedule modules. 1. The datetime module is used to record and plan learning time. 2. The time module helps to set study and rest time. 3. The schedule module automatically arranges weekly learning tasks.
Python vs. C : Exploring Performance and Efficiency
Apr 18, 2025 am 12:20 AM
Python is better than C in development efficiency, but C is higher in execution performance. 1. Python's concise syntax and rich libraries improve development efficiency. 2.C's compilation-type characteristics and hardware control improve execution performance. When making a choice, you need to weigh the development speed and execution efficiency based on project needs.

Python: Automation, Scripting, and Task Management
Apr 16, 2025 am 12:14 AM
Python excels in automation, scripting, and task management. 1) Automation: File backup is realized through standard libraries such as os and shutil. 2) Script writing: Use the psutil library to monitor system resources. 3) Task management: Use the schedule library to schedule tasks. Python's ease of use and rich library support makes it the preferred tool in these areas.
Learning Python: Is 2 Hours of Daily Study Sufficient?
Apr 18, 2025 am 12:22 AM
Is it enough to learn Python for two hours a day? It depends on your goals and learning methods. 1) Develop a clear learning plan, 2) Select appropriate learning resources and methods, 3) Practice and review and consolidate hands-on practice and review and consolidate, and you can gradually master the basic knowledge and advanced functions of Python during this period.
