When we beginners practice programming, it is often difficult to understand the operating principles of simple loops, data structures, and iterations.
Now fear not, we can step through the code with the help of an online tool and visualize it in action.
It is a free educational tool developed by Philip Guo to help students overcome basic obstacles in programming learning and understand the process of each line of source code in program execution.
The online tool has been used by 15 million people in 180 countries.
In addition to Python, there are five languages that support visualization: JavaScript, C, C++, and Java.
Check out the video demo below.
The code execution process is displayed very clearly, where the code runs and the number of variables can be clearly seen. For beginners, it can save a lot of detours and deepen the understanding of code operation.
Well, enough nonsense, let's start researching by ourselves!
