@uhoh I asked a diamond mod if it was okay for you to ask "What profiler should I use for Python?" and got a response "I'd be fine with it. I think some of the issue people have had with the "borderline" questions is they tend also tend to be low effort from the OP, but uhoh has a great track record of asking well researched questions and responding to feedback" so feel free to ask it!
If you use the one-topic-per-answer tag, and software-recommendations, high-performance-computing, I image we'll get several answers, each of them explaining all the pros and cons of their favorite profiler. Since most of our users are in the EST time zone, the best time to ask is at night time in Taiwan.
@NikeDattani okay that's great, thanks! Now I have to "live up" to my reputation and ask a really good question :-) I'd never seen a one-topic-per-answer tag but that's pretty cool!
I've just had my morning coffee and almost out the door, I'll "craft" my question carefully this evening.
I have seen in many presentations and publications, things like a human on a molecule (for example). What software can do this? It's for a presentation I'm doing.
It discourages people from writing an answer that just lists 10 different profilers without saying anything useful about them. Instead we get 10 people explaining their favorite profiler in great detail.
I use cProfile now but I find it tedious to write pstats code just to query the statistics data.
I'm looking for a visual tool that shows me what my Python code is doing in terms of CPU time and memory allocation.
Some examples from the Java world are visualvm and JProfiler.

Project Euler and other coding contests often have a maximum time to run or people boast of how fast their particular solution runs. With Python, sometimes the approaches are somewhat kludgey - i.e., adding timing code to __main__.
What is a good way to profile how long a Python program takes to...
I believe that's what Robert Kern's line_profiler is intended for. From the link:
File: pystone.py
Function: Proc2 at line 149
Total time: 0.606656 s
Line # Hits Time Per Hit % Time Line Contents

I want to use the excellent line_profiler, but only some of the time. To make it work I add
@profile
before every function call, e.g.
@profile
def myFunc(args):
blah
return
and execute
kernprof.py -l -v mycode.py args
But I don't want to have to put the @profile decorators in by ...
My answer to the MMSE question I linked above, gave several advantages and disadvantages of the software I was recommending:
I wish those SO questions about profilers gave some concise pros and cons like my above answer, but unfortunately those SO questions are now closed, so I guess MMSE is the place where we could make this work!
Anyway, 2:30am here, so I'll be back in several hours (night time in Taiwan).
