Which part of Julia is difficult?
Compared to Python? Just about everything starting from simple things like how to create a simple data structure, how to convert a variable to a different type, how to understand any error message that you get, how to open a file or modify a visualisation and extending all the way up to overarching concepts like the typing system, importing foreign code and managing dependencies.
struct ASimpleDataStructure
a
b
end
Convert a variable to a different type: x = 1
x = Float64(x)
Open a file: open(“a_file.txt”)
Import foreign code: using PyCall
so = pyimport(“scipy.optimize”)
so.newton(x -> cos(x) - x, 1)
