As an extra bonus, if you do this you can remove them all automatically:
for arg in args:
assert print("Well, well, well", "said", "he")
To erase all tracks of the debugging statements at runtime, just use the
-O flag. I tend to use a variant of this for debugging systems that have
"complex" concurrency to make it simpler to track "who" "said" what.
I know you can do the same with just grep if you use print - but you have
to ensure that your debugging statements don't span multiple lines.
