thats clever

This isn't quite correct. That isn't a list expression, its a lazy generator. There is no intermediate list of 1s created, rather it yeilds a 1 each time it is requested by the sum function.

Short for letter?

Can someone explain why all these 56++ persons all using same "let" as variable name? let in this code is not python reserver function but variable name.

How does it work tho? If I pass: "thIs is jadEn" it would give "ThIs Is JadEn" which is incorrect, isn't it?

Brilliant!!

nice code but not really correct. This gives an output of [H, o, w, , c, a, n, , m, i, r, r, o, r, s, , b, e, , r, e, a, l, , i, f, , o, u, r, , e, y, e, s, , a, r, e, n, ', t, , r, e, a, l]

good job

cool. really cool.

But good catch for the fact that only small letters are in the text.
