20191106 04:42:33 0600  answered a question  How to create 31tuples with nonnegative entries that sum to 1 If you want to consider all the points satisfying some properties, i guess the best way it to consider those points as forming a set. In your case, the set of points is a polytope. By convenience, you can construct it from a linear program as follows: Then you can do things like:

20191019 04:36:14 0600  commented answer  How to iterate over symbolic coefficients Indeed ! I was thinking of a tutorial instead of just doc, since the way it works is by overriding a default class, not by calling a function. This is a standard pattern in some Python programs, but not in Sage. In particular, i had to copy a part of the source code to insert my hook, so i guess it is not very handy. Perhaps should we propose a better user interface.

20191019 03:20:10 0600  answered a question  How do I write and implement a program in Sage for Windows? You just have to learn the Python language and put your sequence of computations into a function. Basically, you can se Sage as Python bootsted with mathematical typse such as matrices, graphs, etc. There are tons of nice tutorials about the Python language on the web. See also this piece of doc

20191018 17:17:25 0600  answered a question  How to iterate over symbolic coefficients Okay, i am not sure to understand your question in whole generality. However, here is a solution that could be generalized and adapted to your needs. Let me assume that you want to rewrite the exponents of your expression and that those exponents are polynomials. Working on polynomials has the good property that instead of doing some pattern matching as in the symbolic ring, you can use quotient rings. For example, here is what you can do in your previous example: Now, what you have to do is to walk along the expression and apply this recipe to all exponents of the powers that are encountered. A power is a kind of arithmetic operation, so you will have to override the Let us try with your example: Please tell if this is sufficient for your general case. Anyway, you see the TreeWalker strategy, you can also replace other kind of operators (composition, derivation, relation,...), see the (not documented) https://doc.sagemath.org/html/en/refe...
