   2 days ago · The typical usage to break into the debugger is to insert: import pdb; pdb.set_trace() Or: breakpoint() at the location you want to break into the debugger, and then run the program. You can then step through the code following this statement, and continue running without the debugger using the continue command.

   • Printing Variables or expressions. When utilizing the print order p, you’re passing an articulation to be assessed by Python. On the off chance that you pass a variable name, pdb prints its present worth.
   • Moving in code by steps. This is the most important feature provided by pdb. The two main commands are used for this which are given below: n -> step to next line within the same function.
   • Using Breakpoints. This feature helps us to create breakpoints dynamically at a particular line in the source code. Here, in this example, we are creating breakpoint using command b which given below
   • Execute code until the specified line. Use unt to proceed with execution like c, however, stop at the following line more noteworthy than the current line.

   You can also break into the debugger, without modifying the source and using pdb.set_trace() or breakpoint(), by running Python directly from the command-line and passing the option -m pdb. If your application accepts command-line arguments, pass them as you normally would after the filename. For example: Shell.

   How to import PDB in Python?

   • To import we simply use import pdb in our code. For debugging, we will use pdb.set_trace () method. Now, in Python 3.7 breakpoint () method is also available for this. We run this on Python idle terminal (you can use any ide terminal to run). Let’s begin with a simple example consisting of some lines of code. Example: Output:

   How do I use PDB commands in Python?

   • When the Python interpreter executes line2, it will read the breakpoint and open the pdb console. We use pdb commands to navigate the code. We will learn these commands in the next section. pdb is an interactive command line debugger. You can't harness its full potential unless you are familiar with its commands.

   What is PDB in Python?

   • Source code: Lib/pdb.py The module pdb defines an interactive source code debugger for Python programs. It supports setting (conditional) breakpoints and single stepping at the source line level, inspection of stack frames, source code listing, and evaluation of arbitrary Python code in the context of any stack frame.

   How to call PDB from inside a python function?

   • In that case you can call pdb from inside the Python function. To break into the pdb debugger, you need to call import pdb; pdb.set_trace() inside your function. Let's understand this with a nested function example: from . import function3 // logic for function1 function3() // logic for function2 // some database query from . import function2

   What is PDB & how do I use it?

   • pdb is part of Python’s standard library, so it’s always there and available for use. This can be a life saver if you need to debug code in an environment where you don’t have access to the GUI debugger you’re familiar with. The example code in this tutorial uses Python 3.6. You can find the source code for these examples on GitHub.
