> I wonder, when you already run this within PyCharm, why not just set breakpoints and use the PyCharm debugger?

It's not just PyCharm. A debugger can be set up in many other development environments, but it seems some people refuse to use a debugger. I've seen this more in the PHP community, where people swear that they'll never use a debugger and say there's no need to learn because putting `var_dump` everywhere is better.

For sure, packages like these have their places, but if you're using it for debugging, you're doing software development wrong.
