Practice: Lists and Files in Python

Problem: Ocean temperature (ocean_temp.csv) is the file name that will be used

Problem Specification:

(1)Write a function initList (inFile) that takes a file object as parameter and returns a list of values that are read in from the file.

(2)Write a function getSize (aList) that takes a list of values as parameter and returns the value count (i.e. how many numbers in the list).

(3)Write a function getHighest( aList) that takes a list of values as parameter and returns the highest value of the list. You cannot use predefined max function.

(4)Write a function getLowest (aList) that is similar to the getHighest function but returns the lowest temperature. You may use predefined min function.

(5)Write a function getAverage(aList) that is similar to the above two functions but returns the average temperature.

(6)Write a main function that does the following:

(a)Prompt the user to enter a filename, open the file to read. If file doesnt exist, ask the user to re-enter (recommend that your program allow up to three tries, however, no point deduction if your program exits on file not found error.)

(b)Now, call the initList function to get a list of temperature data.

(c)Call the getSize function to get the number count and print out the number count.

(d)Call the getHighest function to return the highest temperature of the list. Print it out.

(e)Call the getLowest function to return the lowest temperature of the list. Print it out.

(f)Call the getAverage function to return the average temperature of the list. Print it out.

(7)Call the main function to execute your program.
