I have the following code that is counting the most used words in the text file. I need to only count the text after the word From, it is a file of email data and I only want to count the email addresses and return the most common email address and the count of the emails

I need to edit it so that I am only counting strings that are after the word 'From' in a text file. Right now it's counting all words, but I just need the From email addresses in a text file. I think the issue if in the if/else loop but nothing I have tried works. Please help!
