Hi$,$ can someone write these $14$ equation in python code?

$A={\displaystyle \underset{i=1}{\overset{N}{}}}(w_i^2{x}_i^2),B={\displaystyle \underset{i=1}{\overset{N}{}}}(w_i^2{x}_i),C={\displaystyle \underset{i=1}{\overset{N}{}}}(w_i^2)$

$D=AC-B^2,G={\displaystyle \underset{i=1}{\overset{N}{}}}(w_i^2{x}_i{y}_i),H={\displaystyle \underset{i=1}{\overset{N}{}}}(w_i^2{y}_i)$

$w_i,=\frac{1}{{}_{y_i}}$

$m=\frac{CG-BH}{D}$

$b=\frac{AH-BG}{D}$

$P={\displaystyle \underset{i=1}{\overset{N}{}}}(w_i^4{x}_i^2[{}_{y_i}^2+m^2{}_{x_i}^2])$

$R={\displaystyle \underset{i=1}{\overset{N}{}}}(w_i^4[{}_{y_i}^2+m^2{}_{x_i}^2])$

$Q={\displaystyle \underset{i=1}{\overset{N}{}}}(w_i^4{x}_i[{}_{y_i}^2+m^2{}_{x_i}^2])$

${}_m^2=\frac{C^{2}P-2BCQ+B^{2}R}{D^2}$

${}_b^2=\frac{B^{2}P-2\text{A}\text{B}\text{Q}+A^{2}R}{D^2}$
