Write a shell (text-based) program, called multiply_stuff. py, that opens a text file called stuff. txt with 3 numbers per line separated by commas. For each line in the text file, the program should print out the result of multiplying the first and third numbers. For example, if stuff. txt has the following lines: 500,55,2 300,45,3 200,7,10 Then the following example output would happen. PS C:\Users\ssiva\Desktop> python multiply_stuff. py 1000 900 2000
