Dump a NumPy array into a csv file

Here's an example code snippet that demonstrates how to dump a NumPy array into a CSV file:

import numpy as np

# Create a NumPy array
data = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]])

# Save the array to a CSV file
np.savetxt("data.csv", data, delimiter=",")

This will save the array data to a file named data.csv in the current directory. The delimiter parameter specifies that the values in the CSV file should be separated by commas.

You could also use pandas, it's more versatile when working with data

import pandas as pd
df = pd.DataFrame(data)
