Taking a class on Python at college in the spring. I’m new to programming. What can I expect and how should I prepare?

Just do some intro python tutorials. Maybe try some easy LeetCode problems in python. But I wouldn't be too worried about prepping for an intro cs class.

Is python a viable language compared to the other top ones?

just learn one and you can learn other ones easily. python is good for beginners unless you're smart, in which case you should start with something like C to build foundations.

Python's definitely the best for ML and any other science data science applications. If you're more pure CS / mathematics you should learn java, rust, etc. I wouldn't try and learn C unless you care about memory management and internal workings of the computer

Python is THE top one. It BTFOs every single other language and I am saying this as someone who really dislikes the language. Thank God I am not in a situation where I have to use it anymore.

You need a PC with Linux installed, and gcc, learn to program in Python, then C, then some assembly. Perl and Lisp dialects are also good, as are some side languages like Haskell or OCaml.
Once you know programming, the rest is easy. None of this is hard, and the class just isn't gonna teach this stuff well, so you need to get started now if you want to have fun.

>>12479425
Depends what you want to do.

Write short automation scripts?
Python
Data science?
Python
Windows desktop applications?
C#
Android apps?
Java
ios apps?
Swift
Performance software?
C++ (possibly rust, havn't tried it yet)
Embedded?
C

I don't know much about web stuff, that's a different game, but very useful.

Expect to be fucking bored. No way you can stretch learning python over a whole college class unless you autistically go over every builtin module and function, or the class is actually a bunch of projects that aren't really about learning the language. DESU just start learning it now. Google some tutorials and go at your own pace. Proficiency doesn't come from classes anyway, it comes from projects.

>What can I expect and how should I prepare?
Getting into the habit of using it.
E.g. something you can try to do right away is write a script that you pass a directory path and two words and it then scans through all its subdirectories and, in. all .txt files, replaces all instances of the first word with the second word.

i have a real job. python is by far my most productive language for modling and simulation. I only write C for embedded performance and fortran for desktop performance, rarely, when performance matters over coding productivity.

C++ is pretty much useless in R&D.

Yes it is. It offers a lot of possibilities without much knowledge.
However, if you want to do more sophisticated things I would recommend other languages.
For someone that may want to write some small scripts for processing some Data, it's fine.

That's cringe as fuck.
Python is just super easy to use and because of that quite nice for scientist and ml.
Also even if you are shit programmer your code will look quite readable in it.
It's definitely not amazing by any different metric(speed, memory management, abstraction, expression power).

most physicists/nuclear engineers who do any sort of radiation transport modeling or detector modeling use GEANT (C++) or MCNP (fortran) or some other tool like SCALE. another widely popular molecular dynamics tools is LAMMPS (C++)
obviously python is hugely popular and simple to use, but when i think of modeling and simulation I think C++ not python

But the codes you mentioned are maintained by dedicated development teams. If you actually want to interface with those programs or process an output you will be using a scripting language. Most of the people who use that kind of software drive it with python and let the optimized compiled codes do the heavy lifting.

Also looking to learn programming to broaden my abilities professionally.
Want to add the ability to do advanced physics modelling and simulation (plasma physics, radiation transport, materials science/molecular dynamics, heat/fluid transfer, etc.)
Took one entry level C course in uni but it was shit, literally the first 6-8 weeks involved no if statements, looping constructs or anything, just writing algorithms using operators and sperging about using %

Tutorialspoint are OK but it's better to use a broad range of resources.
personally I used hhtps://www.codewars.com as a gamified way to learn coding concepts, though I'm stuck at 3 kyu because I'm hitting a knoledge gapl on the more complex tasks.
but generally I complete the kata until I hit a stumbling block and have to learn new concepts
I will say that one should probably ignore the popularity votes for solutions. Generally I've found the community friendly.
