# difflib module is nothing just a module in python which provides functions like comparing data btw files
# SequenceMatcher is a class in difflib which compare the sequence of characters or elements btw files as long as they are hashable
from difflib import SequenceMatcher
# open function opens the files in reading mode
with open('Plagiarism Checker/Text Files/file1.txt') as file1, open('Plagiarism Checker/Text Files/file2.txt') as file2:
    file1_data=file1.read()     # Read file1 data and store that in file1_data
    file2_data=file2.read()     # Read file2 data and store that in file2_data
    # None,1st file,2nd file are passes as an argumnet in SequenceMatcher function and result is stored in similarity
    # None is passed so that not a single element is ignored during comparison
    similarity=SequenceMatcher(None,file1_data,file2_data).ratio()  
    # Now at last print the similarities in the form of %
    print(f"\nThe Similarities between files are {similarity*100}%\n")
