I think you misunderstand several things at the same time here.
1. These errors originate from syntax errors. They are basically Python
errors. It's possible that behind the scenes, PyCharm is running one or
another Python program to detect them, but they are errors in your
Python code.
2. print() doesn't care whether you give it an f-string or not, because
a f-string is a string too.
3. All strings need to be closed with the same kind of quote they
started with. If one is not closed, then Python thinks the string is
supposed to continue, and - say- the final parenthesis of the print()
function looks like it is part of the string. So Python (or PyCharm)
notices that the closing parenthesis of the print() expression is missing.
4. in an f-string, the expression in braces is evaluated and replaced by
its string value. So if you try to do this
print('{LIMIT}')
then that will be printed as is with no substitution - because it is
not an f-string. So you will see "{LIMIT}" But you thought you were
going to see "42" (if LIMIT == 42, that is). OTOH,
print(f'{LIMIT})
will substitute the string value of LIMIT before printing the string.
Both are legitimate but the first is not what you seem to want.
5. As I posted earlier, you almost certainly do not need to add the "\n".
So, some suggestions:
- If you are having a problem with some piece of code, try to simplify
it down to the smallest bit that shows the problem.
- If you are having trouble with f-strings, then think about what you
want to achieve and look up information about f-strings with that in mind.
- If you are having trouble with the print statement, think what you
want it to display and look up information about the print function with
that in mind.
- If your tool - PyCharm in this case - is producing messages but you
don't understand why they are being produced, try to look up information
about how and when PyCharm produces error messages
Do you see a pattern here?
Also note that just because you don't see an error message does not mean
that the code is correct. It may be correct from the point of view of
Python syntax but that doesn't mean that it will perform correctly nor
how you expect.

No error message is displayed.
