Brent''s method, Programming Languages

Assignment Help:
This is what I have so far

def root_brent(f, a, b, errorlimit = tinyerror, n = -1, r_i = 0):
# f(a) and f(b) must have opposite signs
poly = remove_multiple_roots(poly)
counter = 0
if f(a) * f(b) >= 0:
return

if abs(f(a)) < abs(f(b)):
a, b = b, a
c = a
mflag = True

while (not f(b) == 0) and (not f(c)==0) and (abs(b-a)> errorlimit):
if f(a) .... :
s = (a*f(b)*f(c))/((f(a)-f(b))*(f(a)-f(c))) + (b*f(a)*f(c))/((f(b)-f(a))*(f(b)-f(c))) + (c*f(a)*f(b))/((f(c)-f(a))*(f(c)-f(b)))
else:
s = b- f(b)*(b-a)/(f(b)-f(a))

#### Start here
# if (condition 1) s is not between (3a + b)/4 and b
# or (condition 2) (mflag is set and |s-b| = |b-c| / 2)
# or (condition 3) (mflag is cleared and |s-b| = |c-d| / 2)
# or (condition 4) (mflag is set and |b-c| < |\delta|)
# or (condition 5) (mflag is cleared and |c-d| < |\delta|)

# or here is elif

Can ant help me getting past this point.
I am lost on what to do next.
