Can Someone help me: I am from a python background. for loop last interation item variable is globally available in Python. But Julia throws error. Why is it so?. Is there any other way to make that last iteration item variable globally available ie., outside the FOR loop? Please see the code in…

Thanks man… I got it… for i in 1:8897979797897897 try Char(i) continue catch println("Inside Loop",i) global x = i break end end println("Outside Loop",x) As stillyslalom says: "In general, it’s best to avoid global scope, and you could instead…

When you ask why, do you want to know scoing rules defined in the language, or the rationale for making language design choices? Here’s the rules, if that’s what you want: https://docs.julialang.org/en/v1/manual/variables-and-scoping/

thanks man… I got it … thanks for taking time for immediate response…

In general, it’s best to avoid global scope, and you could instead write a function that returns the error-producing i: function errorchar(limit) for i in 1:limit try Char(i) catch return i end end end

Probably not. Multiple dispatch is way more powerful and flexible than OOP.

Multiple dispatch is a form of object orientation, just not the class-based kind. Which is a good thing .

Indeed. In fact, if anyone wants to have python’s way of things, they already can replicate that with Julia: simply define a struct and have all associated methods accept an instance of it as their first argument. After all in python instanceOfClass.methodcall(*args) is just a syntactic sugar of Cla…

I don’t think I have ever seen it used in the wild, but there is the outer keyword that you could use for this; see Scope of Variables · The Julia Language .
