java - Trying to not Omit Leading 0's when writing from Int to Hex using buffered writer -

-

i create buffered writer

bufferedwriter errorreport = new bufferedwriter(new filewriter("errorreport.txt"));

then wanted write while converting integer hex.

  errorreport.write(integer.tohexstring(version))

this works perfectly, except omits leading 0's writes minimum possible length. 'version' byte in length , prints 6. know actual value 06. how keep these leading 0's?

i tried errorreport.write(string.format("%03x", integer.tohexstring(version)), error illegalformatconversionexception x != java.lang.string

the x specifies hexadecimal format perform conversion passing integer directly

errorreport.write(string.format("%03x", version));

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...
