Write a program that counts the frequencies of each word in a text, and output each word with its count and line numbers where it appears. We define a word as a contiguous sequence of non-white-space characters. (hint: split()) Note: different capitalizations of the same character sequence should be considered same word, e.g. Python and python, I and i. The input will be several lines with the empty line terminating the text. Only alphabet characters and white spaces will be present in the input. The output is formatted as follows:
Each line begins with a number indicating the frequency of the word, a white space, then the word itself, and a list of line numbers containing this word.

When we sort a list of items, we need a basis on which to compare the items to see whether one is bigger than another. If it's a list of numbers, Python just compares the numeric values; if it's a list of strings, Python compares the strings alpha..
