This article shows you how the Python tool Heartrate implements real-time visualization, the content is concise and easy to understand, it can definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Real-time stack trace (stacktrace)

The Heartate-- tracking program runs like a heart rate monitor.

Heartrate is a tool library of Python, which can visualize the execution process of Python program in real time. Monitor the running Python program as shown below:

As shown in the figure, the number on the left represents the number of times each line of code has been triggered. The box represents the line of code that was recently triggered-the longer the box, the more the number of triggers, and the lighter the color, the more recently triggered. What can the tool do:

Start program tracking

Start the server in a thread

Open a browser window that displays the visualization of the file called by trace ()

Code call highlighting depends on executing (https://github.com/alexmojaki/executing) library), and due to version reasons, hearttrate only supports versions above Python3.5. Pip is installed as follows:

Pip install-user heartrate
