Performance

cost=0
for i in range(12):
    cost=cost+math.pow(float(float(q[i])-float(w[i])),2)
cost=(math.sqrt(cost))

Any faster alternative to this? i am need to improve my entire code so trying to improve each statements performance.

Performance

I have to read a file from a particular line number and i know the line number say "n": i have been thinking of two choice:

1)for i in range(n) fname.readline() k=readline() print k

2)i=0 for line in fname: dictionary[i]=line i=i+1

but i want to know faster alternative as i might have to perform this on different files 20000 times. is there is any other better alternatives??
