In what way am I using the "&" sign incorrectly?

Ex 4.3 Dichotomy function

var('a','b','N') (a, b, N) def Dichotomy(a,b,N): if f(a)*f(b) >= 0: print "Don't bother me or my wrath shall fall upon you" lb = a ub= b for i in range(1, N): mp = (lb+ub)/2 if f(mp) == 0: lb = mp up = mp if(((f(mp)<0) & (f(lb)<0)) | ((f(mp)>0) & (f(lb)>0))): lp = mp else: up = mp return [lb,ub,ub-lb]
