Is it preferred to use the second approach?
In my opinion: Yes.
As you said, no need to include the pdb module in general.
Therefore import pdb; pdb.set_trace() is a convenient way to include it when debugging, so that easily can be removed when debugging is done. This is the way I always do it, and probably lots of other people do it like that too.

Python Debugging With Pdb – Real Python
May 19, 2023 - If you pass a Python expression as the 2nd argument, pdb will break when the expression evaluates to true. We’ll do this in an example below. In this example, there’s a utility module util.py. Let’s set a breakpoint to stop execution in the function get_path(). Here’s the source for the main script example4.py: ... #!/usr/bin/env python3 import util filename = __file__ import pdb; pdb.set_trace() filename_path = util.get_path(filename) print(f'path = {filename_path}')

You can run your program into pdb from the command line by running
python -m pdb your_script.py
It will break on the 1st line, then you'll be able to add a breakpoint wherever you want in your code using the break command, its syntax is:
b(reak) [[filename:]lineno | function[, condition]]
It is flexible enough to give you the ability to add a breakpoint anywhere.

November 4, 2022 - The major advantage of pdb is it runs purely in the command line, thereby making it great for debugging code on remote servers when we don't have the privilege of a GUI-based debugger. ... To start debugging within the program just insert import pdb, pdb.set_trace() commands.

Breaking into the debugger can be achieved with just a single line of Python code. It’s import pdb; pdb.set_trace(). When execution reaches this point in the program, the program stops and you’re dropped into the pdb debugger. Effectively, this is…

To use pdb, you first need to import it into your Python script. This can be done by simply adding import pdb at the beginning of your file. Once imported, you can set breakpoints in your code by calling pdb.set_trace().

26.2. pdb — The Python Debugger — Stackless-Python 2.7.15 documentation
Pdb is the debugger class. The completekey, stdin and stdout arguments are passed to the underlying cmd.Cmd class; see the description there. The skip argument, if given, must be an iterable of glob-style module name patterns. The debugger will not step into frames that originate in a module that matches one of these patterns. [1] Example call to enable tracing with skip: import pdb; pdb.Pdb(skip=['django.*']).set_trace() New in version 2.7: The skip argument.

The debugger is included in python's standard library and we use it the same way we would with any python library. First, we have to import the pdb module and then call one of its methods to add a debugging breakpoint in the program.
