Python Developer to write a program which copies text from an email and pastes it into my computer

I need a program which when I receive a new email, will scan for a word after a colon, copy this word and paste and enter on another specific portion of my screen instantly. (the coordinates of the screen portion will stay constant). Specific portion is a search bar in one of the program. So that should paste the word in the search bar, and clicks enter. In that time when the email comes in, it should work instantly.

And that time, I might be doing other tasks in my computer too. Also I am using outlook for receiving emails.

Ping me with a plan if you can do this.
