Debugging is the process of locating and correcting bugs in your code. It is a necessary skill for any Python programmer because it can help you enhance your applications’ quality, performance, and reliability. This post will teach you about several standard Python debugging tools and techniques and how to utilise them efficiently. In this blog, we will discuss the What are some popular Python debugging tools and techniques. To learn more about different types of frameworks in Python, you can join the Python Training in Coimbatore at FITA Academy, which will help you understand the oops concept of Python, operators and data types and many other core concepts.
Built-in tools
Python includes some built-in tools for debugging code. For example, the print() function can display the values of variables, expressions, or messages in the console. The assert() statement can also be utilised to check if a condition is proper and generate an exception if it is not. The traceback module is another handy tool that displays the stack trace of a mistake, describing where and why it occurred.
Debugging modes
Python also supports two debugging modes, interactive mode and debug mode, which can alter how your code executes. In interactive mode, you can run your code in the Python shell line by line, inspecting or modifying the variables and objects in the current scope. You can enter interactive mode by typing Python or python3 in your terminal or running a script with the -I option. You can use the pdb module in debug mode to set breakpoints, step through your code, and evaluate expressions. When running a script, use the -m pdb option to enter debug mode or insert the statement in your code. Register in Python Course In Madurai to get into a new learning career with 100% placement.
IDEs and editors
Another option for debugging Python code is to utilise an integrated development environment (IDE) or a code editor with debugging capabilities. For example, prominent Python programming IDEs include PyCharm, Visual Studio Code, and Spyder. These IDEs can provide graphical interfaces for setting breakpoints, monitoring variables, inspecting objects, and controlling the execution flow. They can also work with tools and frameworks to help you debug your code in other situations, such as pytest, Django, or Flask.

Logging and testing
Debugging is not only about discovering errors but also about preventing them. One method is to use logging and testing tools to monitor and validate your code. Logging is the process of logging events and messages that occur during the execution of your code. You can use the logging module to construct and configure loggers, handlers, formatters, and levels and output log messages to various destinations such as files, consoles, or databases. Testing is the process of determining whether your code matches the expected criteria and standards. You can use the unit test or pytest modules to create and execute test cases, suites, and fixtures and report results and errors.

Debugging tips
Finally, here are some general tips for debugging your code more effectively. To make code more understandable and maintainable, use descriptive and consistent names for variables, methods, and classes while adhering to the Python style guide (PEP 8). Use comments and docstrings to document the code and explain its purpose and logic. Version control systems, such as Git or Mercurial, can maintain code changes and history and allow reverting or comparing various versions if necessary. Online resources such as Stack Overflow, Python documentation, and tutorials can also be utilised to look for solutions or examples of similar problems or activities. The rubber duck method, which involves explaining your code or problem out loud to a rubber duck (or any other item or person), can also help clarify your thinking and identify potential problems or gaps.
