Python Pipelines Guideline for Beginners
If you’re a Python developer, you might be familiar with the concept of “pipelines”. But what exactly does it mean? And what benefits do pipelines offer? In this blog, we’ll delve into the concept of pipelines in Python, and the advantages they bring to your code in terms of readability and efficiency. What are Pipelines in Python? So, what are pipelines in Python? For those who don't know, pipelines serve as a systematic arrangement of continuous operations or functions designed to handle data. The output of each operation serves as the input for the subsequent one, creating a continuous flow until the ultimate result is achieved. Conceptually, pipelines can be visualized as a sequence of interconnected pipes, facilitating the smooth flow of data from one pipe to another, undergoing various transformations or manipulations occurring throughout the process. Solution 1: Creating a Loop An approach to do this involves creating a loop that iterates the list and applies each operation one by one, storing the intermediate outcome in a new list. For example: This code works, but it’s not very clean or efficient. It makes three new lists, taking up memory and making the code harder to follow. Plus, it involves writing four loops, which can be a bit tedious and error-prone. > Related: App Development for Your Business - Detailed Guidance Solution 2: Use a Pipeline A smarter way is to use a pipeline. Think of it like a series of connected steps. Instead of creating extra lists and loops, you can link the operations together. To do this, we can use the built-in map and filter. These functions apply a given operation to each element of a group without creating extra lists. There are also the sum and len functions that calculate the total and length of an iterable, respectively. Here’s an example to illustrate this idea: This new code is shorter and simpler than the previous one. It avoids creating extra lists or loops and makes it clear how data moves from one step to the next. However, it’s not super easy to read because it uses nested map and filter calls, which might be confusing. Solution 3: Use the Pipeline Function A better way to make the code more readable is by using the pipe function from the toolz library. The pipe function takes an initial value and a sequence of functions. It then applies each function to the result of the previous one, making it easier to understand the overall flow of the code. For instance: This new code is easier to understand and more elegant compared to the old ones. It clearly shows the sequence of operations that are applied to the data, and it doesn’t use complicated nested calls or extra lists in between. The pipe function makes the code look like a series of connected steps, where the data smoothly goes from one action to the next. Why You Should Use Pipelines? Pipelines are used for several reasons, providing a structured and efficient…
