While you explained the mechanism, i think the examples given were better served by sum(《list》) and reversed(《string》) or slicing or sorted(). You say you use this every day, perhaps a real world example or examples following this explanation of the mechanism would be more helpful than the toy examples alone.

“and then, finally, the ‘d’ comes in”… my highschool self was giggling 🤭😂

Although well presented, I'm not impressed with the value of reduce(). I cannot think of a use case where the same thing cannot be accomplished with one of the simpler functions, such as sum(), max(), min(), any(), all(), etc. Perhaps this is why it's no longer a built-in function.

The functions you demonstrated in combination with reduce are basically just sum and reversed, so you don't show any real value for it.
