Debugging Tips for Python Developers


When debugging Python applications, you may need to know how to interpret the errors in the output of pdb and how to use the gdb debugger to step through your code. Many more tools can help you debug Python applications.

Debugging your code isn’t as easy as it sounds. Sometimes, you might find yourself at a loss for what’s causing a bug to happen. I’ll share some debugging tips for Python developers. You might find this useful when trying to debug an issue, or maybe you want to write a better debugging tool.

We want to take a closer look at debugging tools and Python developers’ methods. When I started in the industry, I was excited to see what new things people had created since I first learned to program. I noticed that most of the things that I learned about debugging are still relevant today.

What is a debugger?

A debugger is a tool that helps you find the source of the error or problem. There are many types of debuggers, such as interactive and non-interactive debuggers.

An interactive debugger lets you review your code and examine your data on every line. A non-interactive debugger is typically an API that can be used from your favorite programming language.

For example, you can use the Python debugger pdb to help you debug your code.

How to debug code?

It’s no secret that debugging is an integral part of software development. You might have heard “debugging is half the battle” before. That means a bug can be traced back to a single line of code.

Debugging can be done in many ways, but knowing which one to use is often difficult. It’s best to use tools that are built specifically for this purpose. Here are a few of my favorite options. Visual Studio Code is a cross-platform IDE for web and mobile app development. With its built-in debugger, you can analyze code as you write it. You can even do this from a terminal or the command line.

My favorite is VS Code Insiders. It’s a free version of VS Code that allows you to access all the same features as the paid version, minus the trial period.

PyCharm is an integrated development environment for Python. It’s a powerful IDE for Python developers. It offers Python debugging, code completion, and a Python interpreter. If you’re into Python and want a more visual experience, you can check out PythonPad. It’s a web-based IDE that’s similar to Notepad++. I use Pycharm and VS Code daily, so I’d recommend trying out both to see which one works best for you.

How to make debugging faster

Debugging is a complex task, and it’s often necessary to start from the beginning when you’re trying to fix a problem.

There are two main approaches: step-by-step and trial-and-error.

Step-by-step debugging is an effective and efficient way to debug code, but it’s quite slow. You must set up a breakpoint at each step and wait for the program to stop. Instead of spending time setting up breakpoints, you can instead use a trial-and-error approach. Write down the line of code you think is causing the issue, run it, and observe the output. If you don’t know the problem, try writing a new function that works fine and compare the results.

You might also use a logging tool to log errors and messages at the console, and you can even use a debugger such as pdb (Python debugger) to step through your code.

How do I debug using the console?

Debugging can be difficult, especially if you don’t know the language well. Fortunately, you can use the Python console to help you solve issues. When an error occurs, the console automatically opens up a window. From here, you can enter commands to help you debug your code.

How to debug with the debugger module

The debugging module allows you to set breakpoints and step through your code, which is extremely helpful when dealing with complex and long programs.

Python is a very powerful language, but debugging is often neglected. As a result, most programmers spend more time debugging than writing code.

Frequently Asked Questions Python Developers

Q: What is debugging?

A: Debugging is finding and fixing errors in your code. Debugging involves running a program and looking at its behavior to determine what went wrong.

Q: How do you debug your code when something goes wrong?

A: First, I use the debugger built into IDLE to step through my code line by line. If that doesn’t work, I’ll use print statements or logging.

Q: How would you describe a bug in terms of its severity?

A: I would say a bug is a defect, but a minor one.

Q: Do you think there is any value in writing unit tests for software?

A: I think it’s valuable because they can help you find bugs more quickly.

Q: Why do you use logging?

A: Because logging gives me a quick view of how my code is doing without slowing me down or causing me to lose focus on what I am trying to accomplish.

Top 3 Myths About Python Developers

1. Python developers can ignore these debugging tips.

2. These debugging tips apply only to Python developers.

3. These debugging tips are only for the beginner.


Debugging is an important skill for a developer to possess. It is the process of finding errors in code. Debugging is necessary for any language, but Python has many features that make debugging easier than in other languages. If you don’t know how to debug, it is hard to become a successful programmer. Debugging is not easy to learn, but it will make you a better programmer. I highly recommend trying different debugging techniques and tools to see what works for you. There are many debugging tools available for Python. I recommend using pdb, a standard debugger you can use in your IDE.
