Give as a python code Exercise $2$: Program periodic surfaces $-$ Periodic surfaces: $\backslash$psi $($r$)=\_$l$=1^$L$\_$m$=1^$M$\backslash$mu $\_$l mcos$(2\backslash$pi $\backslash$kappa $\_$l$($p$\_$m$^$T$$r$))=0\backslash$mu $\_$l m is a periodic moment $\backslash$kappa $\_$l is a scale parameter p$\_$m is a basis vector r is a location vector $1.$ Construct a function in Python with $\backslash$mu $\_$l m$,\backslash$kappa $\_$l and p$\_$m as inputs and $\backslash$psi as output $2.$ Plot P$,$ D$,$ and G types of surface with your function. You can choose any scale parameter.
