Julia, as we know it from our very first introduction, takes the best from both worlds. It matches Python in terms of ease of code and maintenance, while it targets to achieve the speeds of C.
But what if we really need to make outside calls to code or functions written in these two languages? We then require the ability to import the code directly into Julia, and be able to make use of it. Let's see, one by one, how Julia manages to make external calls to these two programming languages.
