Saving a 30-Dimensional Numpy Array to a Human-Readable TXT File in Python

If you've been working with data in Python, especially using libraries like NumPy, you might find yourself needing to save your arrays to a text file. This process allows you to share your data with others who may not use NumPy or for future reference. In this guide, we will address how to take a 30-dimensional NumPy array and save it as a human-readable text file.

The Problem

Let's say you have a 30-dimensional NumPy array, represented in the form of a 2D structure with multiple rows and columns. You want to save this data in a format that is easy to read, perhaps to share with colleagues or for later use. The structure of your array looks similar to this:

Although it is possible to save this data using NumPy’s built-in functions, the challenge lies in formatting it correctly, without extra characters, and ensuring that it is neatly separated.

The Solution

Step 1: Open a File for Writing

Firstly, to save your data in a text file, you will need to open a file in write mode. You can use Python's built-in open function for this.

Here’s how you can do it:
