In $1939$ Ernest Vincent Wright published a $50,000$ word novel called Gadsby that does not contain the letter $$e$.$ Since $$e$$ is the most common letter in English, that$$s not easy to do$.$

In fact, it is difficult to construct a solitary thought without using that most common symbol. It is slow going at first, but with caution and hours of training you can gradually gain facility.

All right, I$$ll stop now.

Write a function called has$\_$no$\_$e that returns True if the given word doesn$$t have the letter $$e$$ in it$.$

Write a program that reads words.txt and prints only the words that have no $$e$.$ Compute the percentage of words in the list that have no $$e$.$Complete part $1,$ the function.

TP$9\mathrm{.}3$bis $[15]($forbidden$\_2.$py$)$ Part $2$ "find a combination of $5$ forbidden letters that excludes...", but write code to solve it$,$ not an interactive program.

This will get you started: words $=$ pd$.$read$\_$csv$(\text{'}$words$.$txt$\text{'},$ header$=$None$).$squeeze$().$str$.$lower$()$

$,$ and itertools.permutations will help, but note there are $7$ million permutations $($len$($list$($itertools$.$permutations$($string$.$ascii$\_$lowercase, $5))),$ so spend a bit of time thinking about how to make it run fast.
