If you enter 100, you will get to how_much = int(choice).
That means how_much is equal to 100.
In the next if statement, we check if how_much is less than 50. 100 is NOT less than 50, so we do not enter the if part of the if statment.
Instead, we enter the else part of the if statement.
Inside the "else" part the dead("You greedy bastard!") code run.
The dead code will print the text you see.
Like I've done before, I would suggest you slow down. You seem to be going too fast. You might be going through the exercises quickly, but if you don't understand them, you won't learn much.
The questions you're asking indicate you're missing some fundamental knowledge. I would urge you to back to earlier lessons, and not progress until you feel you understand basically every line in the lessons you're working on. If parts are unclear, I'm sure people will help you. That said, I would recommend you ask more specific questions.
Instead of "help what does this do" and post all the code for a lesson.
