Numpy size() funksjon | Python

I Python teller funksjonen numpy.size() antall elementer langs en gitt akse.

Syntaks: numpy.size(arr, axis=Ingen)
Parametere:
arr: [array_like] Inndata.
akser: [int, valgfritt] Akse(x,y,z) langs hvilken elementene (rader eller kolonner) telles. Som standard, oppgi det totale antallet elementer i en matrise
Returnerer: [int] Returner antall elementer langs en gitt akse.
