The built-in breakpoint() function inserts breakpoints into your code, allowing you to enter a debugging session at the point where the function is called. This function provides a flexible and intuitive way to integrate debugging into your workflow, using the default Python debugger pdb or any other debugger configured via the PYTHONBREAKPOINT environment variable:
breakpoint() Signature Arguments Argument Description *args Positional arguments passed to the debugging hook. **kws Keyword arguments passed to the debugging hook. Return Value
breakpoint() doesn’t return any value as it calls pdb.set_trace(), entering an interactive debugging session.PYTHONBREAKPOINT environment variable.breakpoint() Examples
With the default configuration:
breakpoint() Common Use Cases
The most common use cases for the breakpoint() function include:
breakpoint() Real-World Example
Consider a scenario where you’re debugging a function that calculates the reciprocal of a number but sometimes encounters a division by zero error. You can use breakpoint() to investigate:
By running this code, you’ll enter the debugger right before the division occurs, allowing you to inspect the argument and the program’s state. This helps you identify and fix issues like division by zero.
Tutorial
Python Debugging With PdbIn this hands-on tutorial, you'll learn the basics of using pdb, Python's interactive source code debugger. Pdb is a great tool for tracking down hard-to-find bugs and allows you to fix faulty code more quickly.
