I’ve been reading all reference materials of Julia seen alot of scopes, … all things. Would you please paint a code of mistake that begineer (especially python developers) do when writing simple like (variable, functions, let, module while, for, scoping, datatypes, dictionaries…etc) Thank your ex…

I think I have a slightly different take on the original question. It is based on a false premise in my opinion. I do not think that anybody telling you “things you should be aware of” is going to help you learn to code in Julia (or any language). Beyond superficial differences in syntax, you will l…

Oops, I shouldn’t have quote the whole expression. It is not all julia code, I meant sqrt(x) such that x is a float and non positive. Sorry

Je, I imagined all the time the mirror answer in a python forum :wink:

What I found really confusing at first is that Vector{Real} is not an appropriate supertype for dispatching on Vector{Float64} and Vector{Int}, and you need Vector{<:Real} instead. Or better yet, don’t constrain to Vector and use AbstractVector{<:Real}. Or better yet, don’t constrain at all if not…

[image] lungben: In Python, every .py file is a module and every subdirectory a package (just a group of modules, not package in Julia sense). In Python, modules are used more extensively than in Julia (probably due to the lack of multiple dispatch), therefore I do not see this as problematic. …

[image] lmiq: Uhm. Either you want to return something and you assign that to a variable in the function call (you mean forget return in these cases? Never happened to me :grinning_face_with_smiling_eyes: ), or the return value is not assigned, and I do not see any reason for concern. It’s no…

[image] lmiq: [image] paulmelis: so a[0:4] in Python would be a[1:4] in Julia This drives me crazy in python. It so so unnatural! (and my background is mostly on Fortran). Once I got used to the Python way it became more natural to me :slight_smile: [image] lmiq: Functional progra…

[image] paulmelis: A weird combination of include files and modules for structuring code, instead of having a Julia file define a module in a predictable way as in Python I might be guilty of that myself. What is the “correct” Julian way to structure code in a large module that I wish to spl…

Cannot agree more! I think suggesting a beginner to read the whole mannual is insane and completely unnecessary.

[image] fph: I might be guilty of that myself. What is the “correct” Julian way to structure code in a large module that I wish to split into several files? Submodules or includes? That’s the thing, it’s both. The standard way to structure a Julia package is to have a top-level file (e.g. MyM…

I don’t know if this count as a beginner situation, but this is the most obscure one that I had have till today
