Arguments in Python are passed by reference, meaning their attributes can be mutated by receiving functions and methods. Functions should make it clear (with naming and documentation) when they will modify input arguments and avoid modifying arguments otherwise. Creating copies of collections and ...
Keyword arguments are one of those Python features that often seems a little odd for folks moving to Python from many other programming languages. It doesn’t help that folks learning Python often discover the various features of keyword arguments slowly over time. When teaching Python, I’ve of...
Python'sprint()method as an exclusive attribute namely,flushwhich allows the user to decide if he wants his output to be buffered or not. The default value of this isFalsemeaning the output will be buffered. Example In the below program, we will learn how to use theflushparameterwith thepr...
Software developers work rhetorically to make meaning through the code they write. In some ways, writing code is like any other form of communication; in others, it proves to be new, exciting, and unique. In Rhetorical Code Studies, Kevin Brock explores how software code serves as meaningful ...

I find that adding thereturnkeyword can sometimes help make the meaning of your code a bit clearer. Use it where you find it will help make your code easier to read and understand. TIP If you want your functions to not return the last line of the function then you’ll have to explicit...
Have a fairly large elixir cluster, where a single node persistently got into a state where it seemed like certain functions were receiving incorrect arguments. Incorrect meaning that in a 3 arity function, the errors we got made it look at the first argument wasn’t passed at all...
