How to Run the Same Python Code for Multiple Input Files

In the world of data processing with Python, handling multiple files is a common task. Often, you'll find yourself writing similar logic for different files, which can lead to verbose and repetitive code. If you've recently encountered a situation where you needed to process two output files that contained similar kinds of data but differed in values, you're likely looking for a way to streamline your approach. Today, we'll explore how to simplify your Python code to effectively run the same process on multiple input files without redundancy.

The Initial Problem

Let’s say you have two files with similar structures, and you want to extract specific values based on some conditions. Your original code looks something like this:

This code works but is not efficient. It involves repetitive code for each file. The goal is to make the code cleaner and easier to maintain, while still giving the same output.

A Cleaner Solution using Functions

A great way to tackle this problem is by defining a function that handles the file reading and processing. This reduces redundancy and makes your code shorter and easier to understand.

Step 1: Define a Function

Begin by writing a function that takes the file name and a label as arguments. This function will perform the data reading and processing for any file you provide.

Step 2: Implement the Function

Here’s how you can implement this approach:

Step 3: Explanation of the Code

Function Definition: The process_file function takes two parameters: name, the file name, and label, which is used for output identification.

File Handling: Inside the function, the file is opened and read line by line. The same logic as before is employed to extract the desired values based on your specific conditions.

Parameterization: The function allows for easy reuse with any file and a corresponding label (like 'upper' or 'lower'), making it clear and straightforward when the output is displayed.

Step 4: Running the Code

When you run the updated code with your input files, you will achieve the same desired results without redundant logic. The printed output will remain:

Conclusion

By introducing functions into your Python code, you can significantly improve the readability and maintainability of your scripts. This approach reduces redundancy, allowing you to quickly add or modify processing logic for additional files in the future. Whether you're a beginner or an experienced Python programmer, embracing a more functional coding style will certainly benefit your programming endeavors.

Now, the next time you're faced with processing multiple input files, you'll have a clear and efficient path forward. Happy coding!
