Python oneliner to differentiate polynomial list

Introduction

Oneliners are powerful and often beautiful solutions to programming challenges (see Acklamization).

Theory

1. D(poly) = 2*0 + 3*1 + 5*2 + 1*3
2. Dpoly = [3, 10, 3]

<syntaxhighlight lang="Python"> poly = [2, 3, 5, 1] # Degrees starting from zero

print( [(i+1)*j for i,j in enumerate( poly[1:] )] ) <syntaxhighlight>
