Piecewise, Sage VS Mathematica

fgv
21 ●1 ●1 ●3

I´m transitioning from Mathematica to Sage. But I don´t know the way to write the piecewise function below in Sage:

f(x,a)= 0 ; x<=a

      (x-a)^2  ;  x>a

How can I do this?

Thanks

Will the following suit your needs?

def f(x,a):
    if x <= a:
        return 0
    else:
        return (x-a)^2

There is also a Piecewise class, but it doesn't look like it will work for what you want.
