Brute force mode - TypeError: can't concat str to bytes

[jasonmichaeljones]

I hope it is not just because i am some huge n00b,, but i get the a typing error associated with attempts to concatenate strings and bytes. I am on python 3.10.4.

Terminal output below:

"What day is today?" asked Pooh
"It's the day we burn this motherf***** to the ground." squeaked Piglet
"My favorite day." said Pooh
