Grasshopper python command combining two if commands - Grasshopper

Hi There, I have a phyton command in grasshopper that is getting a list of y coordinates, x coordinates, and z coordinates. The command is looping through y and x coordinate values and checks ( if y[i] > y[i-1]+3 or x[i]> x[i-1]+3 ) then it adds A to the list. And if not it writes (‘G1’+ X[i]+ Y[i]+ E) But I want the command to also loop through the z coordinates and check if each z coordinate value is bigger than its previous one (if z[i] > z[i-1] and i>0) Then (if true) I want it to add
