print(,flush=True) and assert ,print(,flush=True) doesn't show up in the log correctly

Python Help
1

I have a loop in python, with both regular print() statements, and assert clauses which also do print() statements. Both of them say flush=True.

When the assert happens, it is in the middle near to the end, and not where it really happened…

For example…

2024-01-04T20:30:49.5074889Z looping for secret smartpoint and cdn 
2024-01-04T20:30:49.5446726Z ##[error]Process completed with exit code 1.

Looking at the logs, the traceback is shown right after the line “looping for secret smartpoint and usergws”, but the problem really happened at the bottom of the file “looping for secret smartpoint and cdn”…

This means that even though a normal print statement, and a print associated with an assert happen, they aren’t sequenced in the log file the way. And I have flush=True

Snippet of my code:

print(f'looping for secret {productnamefull} and {originalsecretname} ', flush=True)

and

assert (FoundDefault or FoundEnviron), print(f"Bad things!  secret {productnamefull}-{secretname} does not have a nonprod-unenc.yml file nor a {environstub}-unenc.yml file, the world is ending!", flush=True)

What am I missing, how to fix it?

I’m fairly new to python, so my C/C# stuff is showing, but still…

The most important thing that is missing here, is enough code for others to try to reproduce the problem, in order to see it themselves and understand it. Without that, we are only guessing from your description (and if you don’t know how to solve the problem, then how can you be sure that you’re showing the important parts?).

So, please first try to create a proper example.

Putting print in the assert is not necessary.

assert cond, “message if cond it not true”

This will print a traceback with the message if the cond is false.
