Question

A python function opens file data.csv, reads the data from the file and spits the data into three columns, x, y and z. The data is then printed out.

Function:

f = open("data.csv ", "r")

print('x\ty\tz'.format())

for row in f:

    temp = row.split(',')

    for cell in temp:

        print(cell,end='\t')

    print()

 

data.csv contains:

1.2,2.1,1.1

2.3,3.2,0.6

0.7,1.9,0.1

1.8,2.5,0.3

4.6,2.7,0.9

Write a function write_csv_file that will compute the square of each of these values and write out a new file called output.txt that contains the new data. Ensure that both the input and output data have the same format (i.e. both are comma separated variable files) and that the output numbers are written to 3 decimal places. Verify that the output is correct by read csv file to read in the data, and print the new data out.
