, I'm going to build a simple block-chain prototype with less than 50 lines of Python code (the original code is Python 2, which is divided into parts that are hosted in Gist.) The translator has changed it to Python 3 and put the source on the GitHub and click here to view it. ), let's call it snakecoin. First, define what our blocks are about. In a block chain,

This article mainly introduces how to use only 50 lines of Python code to implement a simple proxy server, and write it in the socket module using the simplest client-proxy-forward principle, for more information, see the following scenario: I need to use the mongodb graphics client on my computer, but the mongodb server address is not open to the internet. I can only log on to host A first, and then conne

Use 50 lines of Python code to create a calculatorIn this article, I will show you how to parse and calculate a four-digit arithmetic expression just like a common calculator. When we end, we will get a calculator that can process expressions such as 1 + 2 *-(-3 + 2)/5.6 + 3. Of course, you can also expand it more powerful. No nonsense. directly add the Code: #!/
