emacs - Interactive function for getting number of packages ready to upgrade? -

-

goal: number of packages ready upgrade minibuffer or console.

remarks: package.el hard grasp elisp beginner - many contexts, implicit state, etc...

emacsclient -e "(list-packages)" gives: "x packages can upgraded: type "u" mark them upgrading", creates new explicit buffer.

maybe possible adjust list-packages package.el in hidden buffer?

refreshing packages archive handled package-refresh-contents , beyond issue.

any appreciated.

epl-find-upgrades gives list of upgradable packages. wrap own command around function, print name of each package returned.

(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...
