Adding message to assert
You are out of luck here. The best way is to define your own assert macro. Basically, it can look like this: This will define the ASSERT macro only if the no-debug macro NDEBUG isn’t defined. Then you’d use it like this: Which is a bit simpler than your usage since you don’t need to … Read more

Basically the console wasn’t logging anything because this particular code snippet was attempting to grab the scrolling area of my window, when in fact my code was setup differently to scroll an entire DIV … Read more
Is there a built-in function to print all the current properties and values of an object?
You are really mixing together two different things. Use dir(), vars() or the inspect module to get what you are interested in (I use __builtins__ as an example; you can use any object instead). Print that dictionary however fancy you like: or Pretty printing is also available in the interactive debugger as a command:
How do I remedy “The breakpoint will not currently be hit. No symbols have been loaded for this document.” warning?
Start debugging, as soon as you’ve arrived at a breakpoint or used Debug > Break All, use Debug > Windows > Modules. You’ll see a list of all the assemblies that are loaded into the process. Locate the one you want to get debug info for. Right-click it and select Symbol Load Information. You’ll get a dialog … Read more
