[regal laurel]

Hello everyone i work in java but i need to work in python for this next project. I got it working as in output but it marks my text as incorrect. can anyone help?

Remember to:

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

it says Unresolved reference 'print'

You should really use PyCharm instead of IntelliJ

[regal laurel]

Is there any benefit per se? I already am familiar with IntelliJ due to my developing

[calm rover]

PyCharm is also from JetBrains, but it's their IDE dedicated for Python, whereas IntelliJ is their IDE dedicated for Java

[regal laurel]

hmmm

fair

let me get it

[calm rover]

PyCharm looks exactly the same as IntelliJ. Any workflows you are used to in IntelliJ will also be present in PyCharm.
You can even see it at the beginning when you open PyCharm for the first time it'll ask you if you want to import your IntelliJ settings.

huge bnus! im doing it rn

[bright fern]

Just make sure to get the community version since the pro one is paid (of free if you are a student).

[calm rover]

Same for IntelliJ btw

[meager plinth]

until recently, intellij ultimate used an outdated python plugin

to provide python support

[bright fern]

True, they are all by JetBrains after all

[calm rover]

I mean there are things for which they don't provide free versions, like e.g. DataGrip

[regal laurel]

i think community edition is gone

oh well i suppose this makes thing easier

[meager plinth]

yeah this change happened some two months ago I think?

[bright fern]

Oh

[meager plinth]

or 3

[bright fern]

last time I used PyCharm was a while ago so forgive me.

But the good news is that you can still download it and use it

[calm rover]

The first half of the answer is basically saying:

Python devs were not smart enough to realize there's a paid version

[bright fern]

ouch.

[regal laurel]

I’m downloading it!

I tried to run python using like cmd lines and such but

It just didn’t work for me at all so

I’m hoping this will work

Also I need GitHub

For my project

[calm rover]

You often need to set up a venv for it to work properly.
PyCharm does that automatically for you

[regal laurel]

perfect!

im trying to do math stuff with this for astronomy

plots and outputs

it can handle all of that right?

physics sim

[calm rover]

sure

matplotlib will probably be the easiest plotting library to use

[meager plinth]

File -> Project from Version Control... lets you import your github project

[bright fern]

NumPy also for maths

[calm rover]

only if you need the performance though. Keep it in plain Python first

[bright fern]

true.

[regal laurel]

i assume my poor laptop will be struggling with all the maths

but i just need results really

its more of a one time calculation

[calm rover]

Computers, even older ones, are surpisingly fast

[regal laurel]

thank you jetbrains

[bright fern]

If they do need speed they can simply implement NumPy if really needed.

That C code does account for somethin' after all

[regal laurel]

I can try to look into it but im not that good at understanding

i dont have any py experience actually

[calm rover]

Why don't you do the calculations in Java then? You already know Java, don't you?

[visual storm]

Java is a pretty solid language

[bright fern]

Maybe they needed Python for other things too?

[regal laurel]

I need libraries for some astrophysical calculations for orbits and i heard python is best for this math stuff while java is more so for game dev

[calm rover]

and i heard python is best for this math stuff while java is more so for game dev
That is absolutely not true

[bright fern]

Well if you want to use NumPy at the go make sure you have pip in your systems PATH and install it with pip install numpy

[visual storm]

python has some very powerful libraries for math and graphical visualization.

[bright fern]

I can give code examples if you wish to

[calm rover]

I need libraries for some astrophysical calculations for orbits
Pretty sure there are also equivalents in Java (maybe even an API for the same thing as in Python)

Do you have any specific libraries in mind?

[regal laurel]

sure sure any help i can get

iD love that thank you

[visual storm]

python makes it easy to think about the question in problem and not about the code, for any serious or complex things though you should use java since you are more experienced. thats my take on it.

[bright fern]

Alright so the jist is

## normal py
numbers = [1, 2, 3, 4, 5]
squared = [x**2 for x in numbers]

## numpy (underhood C)
import numpy as np
numbers = np.array([1, 2, 3, 4, 5])
squared = numbers ** 2

[visual storm]

the both have their fortes :)

[bright fern]

now for simple maths NumPy isn't really needed but for your astronomy math thingy with heavier and lengthier calculations it'll help out

[visual storm]

also check out the decimal library, will help out for smaller numbers

[calm rover]

decimal in Python == BigDecimal in Java
