iterating through multiple equations : <p>I have a problem simplified into the following:</p>

<p>Xn+1 = Xn + Yn</p>

<p>Yn+1= Yn + Zn</p>

<p>Zn+1= Zn+ Xn</p>

<p>I know the values of X0,Y0,Z0 to be equal to 1.
I want to tell python to find the values of X1,Y1,Z1 and then X2,Y2,Z2,...etc. Can anyone help me with that? I think I have to use a nested loop but I am not sure exactly how to go about it. Thanks!</p>
