You can access your entire request object, including information regarding the path, type of request, and browser cookie information. Look at what you’ve got in the variables panel. You can give additional information to the debugger using a launch.json file. For instance, if another process blocks the 8000 port, Django needs a different one to start. If this is the first time you’re working on a Django project, you can install django with pip install django and create a django project using the command Django startproject īut in certain conditions, you will have to override the defaults. When starting the debugger, you only have to select the framework in the dropdown. In most cases, you don’t have to configure anything special for these frameworks. VSCode supports popular frameworks such as Django, Flask, FastAPI, and Pyramid out of the box. Configuring VSCode to debug popular Python frameworks. That’s why live debugging is the more brilliant way to find and fix issues in your code. Great, we could narrate everything line by line while our script was running. As we execute line number 8, the value of ‘v’ increases by the value of ‘i’ at that time. Notice that we get to line number 8 only when the value of ‘i’ is odd. As we step inside the loop, you can see the value of ‘i’. You see, the value of ‘v’ is changing as well. The value of v is available because the interpreter hasn’t executed line number 4 yet.īut as you keep clicking on the step-in key. Under the ‘local’ area, we see the value of n is 100. As we are now within the function, the scope changes. Pay attention to the variables section in the sidebar. It is within the process I call (line number 4.) This line calls a function called ‘sum_odd_numbers.’ As I click the step-in key, the interpreter moves to the following line but stops there. My first breakpoint was on line number 14. Please see the below recording to understand how it works and how useful it is. It’s the down arrow key on the debugger toolbar. I find the step-in button extremely useful. The stop button will stop the debugger, and the refresh button will restart the debugger all over again. The play button will ignore the breakpoint and move on to the next. The toolbar is the controller for your debugger. Here’s how:Īs it stopped in the breakpoint you created, you can now see the line is highlighted, the sidebar has changed, and a new toolbar appears on the top right (this location may differ in your window) corner. You can start a debugger in just three steps. Related: How to Create Progressive Web Apps (PWA) in Python? Debugging Python scripts with breakpoints in VSCode. Related: How to Create Stunning Web Apps for Your Data Science Projects Let’s break this section into three: debugging with breakpoints, configuration for popular frameworks, and debugging data frames. That’s what the remainder of this post is about. To my surprise, debugging with VSCode is easy for beginners. Yet, I switched to VSCode, because it’s free, and its community was (and still is) skyrocketing. I was one of them who fell in love with this excellent IDE. ![]() Then came the revolutionary Sublime Text and Atom editors. Some of us started coding in Notepad apps. Live to-debug is a way to speak with your code when running. Related: This Is How I Create Dazzling Dashboards Purely in Python. Modern IDE like P圜harm and VSCode allows you to stop the code at a specific line and inspect all the local and global variables. ![]() That’s a lovely way to debug Python code. ![]() Icecream makes the life of a developer easy by automatically adding context to every log it creates. Use it to test whether your code reaches a point or check a variable’s value at a specific topic. Because that’s the easiest and most widely available choice, it also seems to work fine for smaller scripts. Naturally, anyone who wants to know what’s happening in their code uses print statements. Perhaps ‘print’ is the most used Python function of all. But they know how to find and fix them quickly.

In this post, I’ll take you through what I consider the bad, the lovely, and the intelligent ways of debugging Python code. Some had changed, and some I discontinued. As a self-taught Python programmer, locating issues and fixing them in the quickest possible way was challenging.īut over the years, I learned several techniques to spot bugs in my scripts. I’m sure that’s common with most code newbies. It took me some time to grasp the idea of debugging.
