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.
