python - Excluding web links with specific extensions in web scraper -

-

i need exclude printing links in web scraper end in .od .jpg .pdf or .mp3

here's if statement

if link in linklist():       print link

is there library in python that? know of"regex" i'm not greatest user of it.

assuming link path, can following:

import os if os.path.splitext(link)[1] not in ['.jpg', '.pdf', '.mp3']:     print link

the function splitext takes path , returns tuple containing path without extension, followed extension. example:

>>> os.path.splitext('http://www.example.com/path/to/filename.ext') ('http://www.example.com/path/to/filename', '.ext')

so if split link function, can check whether last element of tuple member of list/set/tuple containing blacklist of extensions.

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...
