Golang: everything you need to know about maps
Maps are pretty similar to dictionaries in Python. In the below, I define a map called red_paints. In this map, I detail the name of the specific red colours for a few companies. When we […]
Golang: Writing test cases in Go
In this article, we’re going to look at how we write test cases in Golang. Here, I will create a file called acct_test.go; which can be run by simply typing go test into the terminal. […]
Golang: Getting to the Pointers
Golang uses memory management for our variables so updating values in our structs as we defined in the previous article, doesn’t necessarily work as we expected. Let’s say we have the below, this piece of […]
Golang: Getting started with structs

Golang: Reading and writing files
Reading and writing files is a key part of most applications. In Golang, it’s not quite as straightforward as with other languages like Python, but let’s go through it line by line to understand how […]
Golang: Getting started with If statements
If statements in Golang are pretty simple, so this is going to be a really short article. What I would like to do, is compare the same if statements in Python and Golang to give […]
Golang: Multiple return values from functions
Okay, so in this article, we’re going to talk about a few things. We’re going to look at how we return multiple values from a function; within that function we’re also going to take subsets […]
Golang: Getting loopy with loops
The simplest form of for loop in Golang is a while loop. What?! Yep, it’s true! In Golang, there are only for loops but they double as while loops. In the below, we have a […]
