How to delete all the lines in one go in emacs? -

-

i want delete lines below particular line of emacs ? there any shortcut key can delete lines below particular line?

c-u 9999999 c-k should trick.

if not @ beginning of first line want kill, use c-a c-u 9999999 c-k.

(the 9999999 can number larger number of lines want kill.)

an alternative using c-u 999999 hold down control key , hold down 9, get, in effect: c-9 c-9 c-9 c-9 c-9 c-9 c-9 c-k.

(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...
