i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...

what following loop do? when program break out of loop? for (c = 0; n; c++) { /* . . . */ } here example of such loop in answer on so . the loop break when n becomes 0 (in other words, loop not stop until n becomes 0 ). can happen within loop (the loop body sets n 0 eventually), or possibly happen because of external event. examples of external events shared memory update, or modification signal handler. c variable incremented many times loop body entered for loop. c variable initialized 0 . technically, code fragment not for loop, controlling construct of for loop statement. fragment missing loop body. that's okay, since question title "this for -loop structure". question title , post has since been modified. you link function in different answer, seem understand purpose of function count number of set bits in number.
