How to find common words and print them using python command?

Question

I want to cross check names from two word documents and then print the common names in the same program. How do I do so? Do I use regex or simply use the in function?

Answer 1

Once you have the text out of the Word documents, it's really quite easy:

document_1_text = 'This is document one'
document_2_text = 'This is document two'

document_1_words = document_1_text.split()
document_2_words = document_2_text.split()

common = set(document_1_words).intersection( set(document_2_words) )
unique = set(document_1_words).symmetric_difference( set(document_2_words) )

If you're not sure how to get the text out of Word docs:

from win32com.client import Dispatch

def get_text_from_doc(filename):
    word = Dispatch('Word.Application')
    word.Visible = False
    wdoc = word.Documents.Open(filename)
    if wdoc:
        return wdoc.Content.Text.strip()

Answer 2

str1 = "Hello world its a demo"

str2 = "Hello world"

str1_words = set(str1.split())

str2_words = set(str2.split())

common = str1_words & str2_words

output:

common = {'Hello', 'world'}
