*pi) with stepsize 0.05*pi that shows as label $\alpha$ and the current value only in the format $x*\pi$

Wouldn't a slider for $x_r\in\left[0~1\right]$ and a label reporting `"\alpha = 2\pi{}".format(x)`

do the job ? Of course, in the computation, you'd have to use $\alpha=x_r\cdot2\pi$. So what ?

So make a slider from 0 to 2 with step size 0.05 and then multiply that

`x`

by`pi`

. Did you have some trouble doing that? What did you try?
