"Python Diff Tool"

Here is a simple implementation of a diff tool program in Python using the difflib module:

Explanation:

• The code uses the difflib module to compare the contents of two files and generate a unified diff, which is a summary of differences between the two files.
• The compare_files function takes two file names as input and returns the unified diff of their contents.
• The code sets the file names and calls the compare_files function to show how the contents of two files can be compared and the diff between them generated.
