Launch Firefox with Python 3.x -

-

i'm trying write script launch firefox me, open google in new tab, , able search (for instance, www.espn.com). i'm trying achieve using webbrowser module, run error each time try launching firefox script. also, firefox not default browser.

import webbrowser webbrowser.get('firefox').open_new_tab('http://www.google.com')

whenever run following error:

traceback (most recent call last):   file "c:/python33/test bing.py", line 6, in <module>     webbrowser.get('firefox').open_new_tab('http://www.google.com')   file "c:\python33\lib\webbrowser.py", line 53, in     raise error("could not locate runnable browser") webbrowser.error: not locate runnable browser

i'm unsure why script struggling locate firefox.exe have tried specifying in 'firefox' actual location of firefox.exe in c: still same error.

i'm sure there's small error in code can't see, if point out i'm doing wrong i'd appreciate it!

i have firefox installed on windows machine well, , have same error.

if run following 2 lines in idle:

import webbrowser print webbrowser._browsers # or print(webbrowser._browsers) python 3.x

then you'll dict of available browser controllers, said in source code. on system prints:

{'windows-default': [<class 'webbrowser.windowsdefault'>, none],      'c:\\program files\\internet explorer\\iexplore.exe': [none, <webbrowser.backgroundbrowser object @ 0x01baf6b0>] }

i think it's worth noting have ie, chrome , firefox on computer , looks "default" , "internet explorer" given here. according the documentation, keys 'firefox' , 'mozilla' should work, of course not.

going source code, in line 539 563, looks python register browser if corresponding (hard-coded) key (e.g. 'firefox' or 'chrome') considered command (using _iscommand(cmd) line 121.

i closed idle , added firefox path %path% , found after restarting idle, _iscommand('firefox') returns true , webbrowser.get('firefox) returns <webbrowser.backgroundbrowser object @ 0x01bdf7f0>. however, webbrowser._iscommand("chrome") still returns false , webbrowser.get("chrome") still throws aforementioned exception.

my conclusion unless webbrowser module changes not rely on %path% (at least on windows), you'll have add firefox path %path% variable first, or make assumption firefox default browser.

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...
