Thoughtlessly Thought Thoughts

Durstöbert man die Python FAQ, so stößt man dabei auf die Frage, wie man denn möglichst unüberschaubaren Code in Python schreiben kann.

Die Antwort ist folgender verschachtelte Lambda-Audruck, um die Mandelbrotmenge (,,Apfelmännchen”) zeichnen zu lassen.

print (lambda Ru,Ro,Iu,Io,IM,Sx,Sy:reduce(lambda x,y:x+y,map(lambda y,
Iu=Iu,Io=Io,Ru=Ru,Ro=Ro,Sy=Sy,L=lambda yc,Iu=Iu,Io=Io,Ru=Ru,Ro=Ro,i=IM,
Sx=Sx,Sy=Sy:reduce(lambda x,y:x+y,map(lambda x,xc=Ru,yc=yc,Ru=Ru,Ro=Ro,
i=i,Sx=Sx,F=lambda xc,yc,x,y,k,f=lambda xc,yc,x,y,k,f:(k=4.0) or 1+f(xc,yc,x*x-y*y+xc,2.0*x*y+yc,k-1,f):f(xc,yc,x,y,k,f):chr(
64+F(Ru+x*(Ro-Ru)/Sx,yc,0,0,i)),range(Sx))):L(Iu+y*(Io-Iu)/Sy),range(Sy
))))(-2.1, 0.7, -1.2, 1.2, 30, 80, 24)
#    \___ ___  \___ ___  |   |   |__ lines on screen
#        V          V      |   |______ columns on screen
#        |          |      |__________ maximum of "iterations"
#        |          |_________________ range on y axis
#        |____________________________ range on x axis

Und weil ich sowas immer schlecht ,,einfach so” glauben kann, habe ich es ausprobiert. Und ja - richtig! Das Ergebnis ist folgendes:
