passing polynomial coefficients generated from one function to another
<p>Since I have been writing a big python program for my project. I have another query of which I cant figure out the solution. Here is the code. </p>

<pre><code>poly = [[k6,3], [k5,2], [k4,1], [k0,0]]

w = 5  # weight for rational bezier curve equation

def time() :
    with open(transcriptionFile, "r") as tFile :
            for line in tFile :
                li = line.split()
                if li :
                    start_time = (int(li[0]) / 10000000.)
                    end_time = (int(li[1]) / 10000000.) 
                    duration = ((int(li[1]) -int(li[0]))/10000000.)
                    print start_time,' ',end_time,' ',duration
                    poly_coeff(start_time, end_time, duration)

def poly_coeff(stime, etime, dur) :
    """The equation is k6 * u^3 + k5 * u^2 + k4 * u + k0 = 0. Computing the        coefficients of this equation."""
    """Substituting the required values we get the coefficients."""
    t_u = dur
    t0 = stime
    t3 = etime
    t1 = t2 = (stime + etime) / 2
    w0 = w1 = w2 = w3 = w
    k0 = w0 * (t_u - t0)
    k1 = w1 * (t_u - t1)
    k2 = w2 * (t_u - t2)
    k3 = w3 * (t_u - t3)
    k4 = 3 * (k1 - k0)
    k5 = 3 * (k2 - 2 * k1 + k0)
    k6 = k3 - 3 * k2 + 3 * k1 -k0 
    print k0, k1, k2, k3, k4, k5, k6

if __name__ == "__main__" :

    if len(sys.argv) != 2 : 
        Usage() 

    else :
        transcriptionFile = sys.argv[1]

        time()

    Newton(poly, 0.42, 1, 0)
</code></pre>

<p>There is a list of start time, end time and their duration. All of them are passed to the function poly_coeff() to generate the polynomial coefficients. There will be as many as there are in the list. Then for each polynomial generated, its corresponding coefficients should be passed as poly to Newton() function to carry out other calculations. And at the top, the polynomial is represented as poly. In poly, each k6, k5, k4 and k0 values generated should be passed. Of course it is not how to do but just to clear what I am trying to do. Please help. Thank you very much.  </p>
