The Leo editor, which I use, checks the file you are working on for
syntax errors and also for undefined variables, missing imports, and the
like, when you save it. It gives you a clickable link to the line in
question. This is a good compromise because it stays out of your way
until you take a break by saving.
I am bullish on F-strings, but they can stretch the typing fingers and
strain the eyes. Remember the days when pythonista used to make
deprecating remarks about the superiority of Python's syntax because we
didn't have 'all those braces' (and other punctuation-characters)
cluttering-up the code???
When you get right down for it, there isn't much difference between
'Here is the result: %s, %s' %(a.b, c)
and
'Here is the result: {}, {}'.format(a.b, c)
Readability and typeability aren't much different. It's only when we
get to f-strings that there's a real change, and the second form started
to prepare us for it (yes, I know that the .format() form lets you use
your own formatter - probably a real advantage though I never had
occasion to use it)

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})
^ I think this one should be:
print(f'{LIMIT}')
with the closing quote ;o)
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.
and Pycharm stopped complaining about it... WHY??

Re: Pycharm IDE
Kevin,
As mentioned in another response, the format of these messages seems
very confused.
Please copy-paste all of (the pertinent part of) the code, and ensure
that the line-endings are in the correct places, tab/indentation looks
correct, etc?
(this will allow us to copy the same code into our PyCharm software and
see what is happening!)
There still appears to be both an apostrophe (') and quotation-marks
("). Do you want the user to see one/both?
There was mention of this being an input prompt - hence the
question-mark. Are you aware that this could be done as part of the
input() function?
How about creating a string and then printing that, eg
prompt = f'"I am thinking of a number between 1 to {LIMIT}"
print( prompt )
NB because of the question asked earlier, the above code is NOT
syntactically-correct Python!
NBB am assuming there's previous code which defines LIMIT

I'm not sure what error you are talking about, but the f-string isn't
closed (and doesn't appear to need the double quotes, either, though
that is not an error). So -
print (f'I am thinking of a number between 1 to {LIMIT}')
(print() will add its own newline at the end so you don't need the \n
unless you actually want another newline).
Next time, please include the actual error message and make sure you
include line breaks so things don't run together.

The code is a bit difficult to read (wrapping), but the error message

Should the line be:
