PYTHON

Write a parsing program which parses input text into tokens and outputs a frequency list showing the number of times each token appeared in the input. The program must use five files.

The first file, called thejobfile, contains only the names of the other files to be used. The user will be asked for the name of this file, which can be assumed to exist in the same folder as the program. The program will not change the contents of this file. The file will have four lines of data; each line is the name of one of the other four files
