Good morning,
I am trying to fix Deprecation Warning in my interact but I don't really know how to change the syntax to fix this warning. It says:
:16: DeprecationWarning: Substitution using function-call syntax and unnamed arguments is deprecated and will be removed from a future release of Sage; you can use named arguments instead, like EXPR(x=..., y=...)
:22: DeprecationWarning: Substitution using function-call syntax and unnamed arguments is deprecated and will be removed from a future release of Sage; you can use named arguments instead, like EXPR(x=..., y=...)
DeprecationWarning: Substitution using function-call syntax and unnamed arguments is deprecated and will be removed from a future release of Sage; you can use named arguments instead, like EXPR(x=..., y=...)
self._f(**dict([(k, self._last_vals[k]) for k in self._args]))
Could anyone help me?
The original is here:

show(plot(f, (x, a-0.5, b+0.5), color="red") + rects)
priblizna_hodnota = sum([ sqrt((xz[q]-xs[q])^2 + (yz[q]-ys[q])^2) for q in range(pocet_deleni)])
