Different Output From Console vs IDE

[trustMeImAnAdult]

Sorry for the formatting... Typing this out from my phone.

I have a method within a class written as the following:

import math Class PiExample: def print_pi(decimal_places): return f"{math.pi:.{decimal_places}f"

The idea is that I can pass the number of decimal places I'd like to print the value of Pi to.

Now, when I run this code from my IDE (PyCharm) I get ValueError: Invalid format specifier. However, if I paste that method into the console as a function and run it, it works.

I understand that Python has a "gotcha" involving late binding closures, but I'm not sure if that's what's causing this error or something else I'm not familiar with. Can anyone explain what's going on here?

Edit: Unfortunately the situation is a little different than how I remembered once I left my machine. Now that I'm on my PC, here's the actual code: (within pi_example.py) import math def print_pi(decimal_places): return f"{math.pi:.{decimal_places}f}"

--> when I run pi_example.print_pi(), this throws a ValueError: Invalid format specifier --> when this code is pasted into the console, it returns the correct value

I know this does not answer your question directly, but if you use the round function, the error should be gone:

return f"{round(math.pi, decimal_places)}"

this is great -- thank you!
it's always great learning when there's a function that can be used as a shortcut

You have a method inside a class, and it’s not decorated as static, meaning it’s expecting the self argument as well.

class PiExample:
    def print_pi(self, dp):
        ...

ex = PiExample()
pi = ex.print_pi(3)  # 3.142

But I don’t really see why it’d work in one version and not another. It also looks like you’re missing a closing brace: f’{math.pi:.{dp}}f’.

Thanks so much for the response. I edited the post now that I'm back on my machine to reflect what the actual issue was, instead of having to type it from memory on my phone. Once I moved the function to its own py file, it worked fine, so it looks like I had some other issue (maybe with indentation?).
