In this tutorial we look at control flow for our scripts. We take a look at IF ELIF and ELSE statements and how to use those to let out code make decisions. We also talk briefly about modulo and modular arithmetic. This can sometimes be a bit confusing if you haven't worked with it, but it is very handy for creating patterns. 

#If/Else Statements
 
import rhinoscriptsyntax as rs
 
color01 = [255,0,255] #magenta
color02 = [0,255,255] #cyan
color03 = [125,38,205] #purple
 
rs.EnableRedraw(False)
 
for x in range(0,100,1):
    for y in range(0,100,1):
        pt = rs.AddPoint(x,y,0)
        if x % 3 == 0 and y % 5 == 0:
            rs.ObjectColor(pt,color01)
        elif x % 3 == 0 or y % 5 == 0:
            rs.ObjectColor(pt,color02)
        else:
            rs.ObjectColor(pt,color03)
 
 
rs.Redraw()
