java - How do I use special characters in a dot file node_id? -

-

i looking forward write script automatically take input file , declare nodes , edges, , produce graph can visualized in visualization software.

i tried dot language , graphviz. language uses grammar declare nodes of graph this: node1;, node2; , not allow special character except _.

it works in cases when want declare node named java.lang.object shows grammatical error because of presence of . , can't change grammar.

can me suggestion other language can take input text file , can draw graph on visualization software.

that's quite easy in graphviz, put quotes around node names. or may define first node using simple identifier , label attribute.

both techniques demonstrated here:

digraph g {   "java.lang.object" -> "my.class";   "my.class" -> "special < chars >";   n1 [label="more.strange<node>names"];   "special < chars >" -> n1; }

-
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...
