How to Dynamically Name a Dataframe in Python Using a Loop

In the world of data science, working with multiple datasets and dynamically processing them can present various challenges. One common scenario is needing to name result dataframes dynamically based on the datasets you are analyzing. For instance, when handling numerous dataframes containing chemical compounds and their corresponding material types, how can you create results dataframes without the hassle of manually renaming each one?

This post addresses this problem and provides a robust solution using Python.

Understanding the Problem

Let's assume you have several datasets structured like this:

You are applying a linear regression model to these datasets, where each dataset contains various chemicals and a categorical variable that lists the type of material. The objective is to create a separate dataframe for p-values from your regression results, with names that reflect their corresponding datasets—like pvalues_first, pvalues_second, etc.

A Solution: Using a Dictionary for Dynamic Naming

To achieve dynamic naming, you can use a dictionary in Python. This allows you to store your results without the need for creating multiple separate variables for each dataframe.

Step-by-Step Implementation

Define Your Dataset Names: Create a list of names for your datasets.

Conclusion

Dynamic naming of dataframes in Python can significantly streamline the process of managing results from multiple datasets. By using a dictionary, you not only simplify your code but also enhance its readability and maintainability. This approach proves beneficial when dealing with extensive datasets, allowing for quicker adaptations and analyses.

Now, whether you're handling chemical compounds or any other datasets, you can efficiently manage your results with ease. Don't hesitate to implement this technique in your projects!
