I recently came across this lesser known feature in Python and started to play around with it. Being able to chain comparison operators is a rarity among most modern programming languages, which is a shame considering how elegant and intuitive it turns out to be. Here are some examples: ```Python a, b, c = 5, 10, 15 print(a < b < c) # True ``` The code above is equivalent to: ```Python a, b, c = 5, 10, 15 print(a < b and b < c) # True ``` And something a bit more complex: ```Python a, b, c, d, e, f, g = 5, 10, 30, 20, 15, 0, 0 flag = a <= b > f < c > d is not f is g print(flag) # True ``` That is all equivalent to: ```Python a, b, c, d, e, f, g = 5, 10, 30, 20, 15, 0, 0 flag = a <= b and b > f and f < c and c > d and d is not f and f is g print(flag) # True ``` You can see how tedious things might get. Python continues to amaze me with how beautiful and concise it can be.
