regex - Match a string with regexp -

-

i having string like

-------- agg x y port-16385-info    ----------------------------+

i want extract "agg x y port-16385-info ". pattern in not same. can have number of spaces inbetween .

help me regexp string.

i using regexp 

regexp {\s+(.*)\-\-*} $a -

ouput 

agg port-16385-info    ---------------------------

this not want. me regexp.

well, i'll assume delimiter @ least 2 - long , seperated via space contents. trivial regex like

--\s+(.*?)\s+--

would work. *? quantifier non-greedy matching, terminate possible.

if regex works depends on allowed values , exact format of input, have not sufficiently explained.

i suprised tagged perl — quite sure code isn't valid perl code.

if not want use . character class, can rewrite match non-hyphen characters or single hyphen followed non-hyphen:

--\s+((?:[^-]+|-[^-])*)\s+--

regular expression visualization

you might want disallows newlines along hyphens well.

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...
