You need to convert your symbolic expression to a symbolic Taylor series, then to a formal power series.
Typical example:
sage: f=sin(x)+cos(x)
sage: g=f.series(x,28)
sage: h=QQ[['x']](g)
sage: h.pade(4,4)
(127441/6601*x^4 - 481140/6601*x^3 - 2632500/6601*x^2 + 709560/943*x + 749040/943)/(x^4 - 10940/6601*x^3 + 265500/6601*x^2 - 39480/943*x + 749040/943)
