python scripts for data mean from a text file data is divided by delimiter (here we use "," as delimiter)

Here's an example Python script that reads data from a text file, calculates the mean of each column, and prints the result:

In this script, we use the `np.loadtxt()` function from the NumPy library to read data from a text file called `data.txt`. We specify that the data is separated by commas (,), using the `delimiter` parameter.

Next, we use the `np.mean()` function to calculate the mean of each column of the data. We specify `axis=0` to calculate the mean along each column. The result is a NumPy array containing the mean values for each column.

Finally, we use a `for` loop to print out the mean values for each column. The `range()` function is used to loop over each column, and we use string formatting to print the column number and mean value for each column.
