Question

*python 3.1

Write and test the following function:

def median_scores(fv):
    """
    -------------------------------------------------------
    Determines the median of a series of integers in a file.
    Use: m = median_scores(fv)
    -------------------------------------------------------
    Preconditions:
        f - a file variable for a file of integers (file)
    Postconditions:
        returns
        median - the median of the values in the file (float)
    -------------------------------------------------------
    """

Here a median is the middle element of a sorted list if the number of elements is odd, and the average of the two middle elements if the number of elements is even. You may use Python's built-in sort method to sort the contents of the list after they have been read from the file.

Use the file numbers.txt. for testing.
