There are a number of good Python tutorials and other doc available. Check the site <http://www.python.org> (I can't tell whether you have Python experience; Python is the implementation language for most of Sage). > I wanted to write a script where I evaluate a function which is also > written in a script. this can be done in Octave , f. ex. by using > "feval", but I have not found anything similar in sage. could anybody > give some suggestion? I'm not sure what you want from your description. However: sage: def foo(x): ...: return bar(x) ...: sage: def bar(y): ....: return y*y ....: sage: foo(10) 100 Is this what you mean? 'foo' and 'bar' can be defined in different files, as long as you have both files loaded when you call foo(). You can also pass functions as arguments: sage: def foo(x, f): ....: return f(x) ....: sage: def bar(y): ....: return y*y ....: sage: foo(10, bar) 100 Does this help? If not, please clarify; we're happy to help.
