linux - echo the type of terminal being ran -

-

i'm trying echo type of current terminal being ran. instance if running konsole echo konsole. i've tried running 

echo $term

but prints out xterm every time. there better , more accurate way of doing this?

pstree can help.

$ pstree -s $$ init───gnome-terminal───bash───pstree

the -s option shows parents of specified process.

in bash (and bourne-shell variants), $$ denotes pid of current shell.

another invocation (while running xterm returns):

$ pstree -s $$ init───xterm───bash───pstree

specifying -a option makes pstree use ascii characters can parse output easily:

$ pstree -a -s $$  init---gnome-terminal---bash---pstree

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...
