Get started with Part I.
Why is a grouping of functionality preferred?
The answer lies in the flexibility it provides. For example, using this programming style, we may choose to create utility functions that can be used across various Python scripts, thereby allowing us to modularise the overall project.
Additionally, it also minimises the chance of accidentally modifying the code that does not require any alteration. As a programmer, we can get a clear idea of which function is causing an error, thereby, focusing only on that particular piece of code.
Consider a scenario that requires a particular task to be executed quite often. If we code it using procedural programming, it involves writing the same piece of code over and over again, and it is not a good programming practice.
Instead, if we use functional programming that defines a function for that particular task, we can call it whenever required without having to repeat the code.
Having this knowledge in mind, we can appreciate how different programming styles enable us as a programmer to code efficiently. Or to say, it allows answering, what programming style is more apt given the scenario.
Stay tuned for the next installment in which Jay will discuss what OOP is and why it is required.
