Your program in python must produce the correct results for valid inputs. However, it is not expected to handle
invalid inputs (such as negative values). Thus, it is unnecessary to use selective or repetitive control
statements (ifs and loops) in your program.
The formula for the area A of a circle is A = arwhere r denotes the radius. For this calculation, you will
use the value of it provided in the Python math module. After importing the math module, the name
math. pi represents a close approximation to the value of a.
To estimate the number of plants needed for a flowerbed, divide the area of the flowerbed by the area
needed per plant (the square of the recommended distance between plants) and then truncate this result.
To truncate a value of type float, convert it to a value of type int (using the int function).
The program named example. py that is attached contains example usages of many of the Python
features you will use in this project (with explanations in the comments)

Develop the program incrementally: a) start by reading and displaying each line of the input file to make sure you are reading the data set correctly. b) use the split string method to extract information from each line into a list. print the list to prove that this step is working correctly. d) convert the exam scores to type int and calculate the student’s average. display those items to prove this step is working correctly. e) create a tuple containing the six items for each student (name, exam scores, exam mean). display the tuples to prove this step is working correctly. (optionally, you may want to have the exam scores in a list so your tuple is (name, scores_list, f) append each tuple to a list. display the list to prove this step is working correctly. g) use the sort list method to re-order the tuples in the list. display the list to prove this step is working correctly. h) use a for statement to display the contents of the list as a table (with appropriate formatting). i) use a for statement to calculate the average of all scores on exam #1, then display the results. note that you could have calculated this average within the first loop, but we are explicitly requiring you to do this calculation by looping though your list of tuples. j) add the logic to calculate the average of all scores on exam #2, then display the results.
