Handle variable name
Dear all,
I would like to pass a function as a parameter and also one of its variable. The simplest situation would just to evaluate a function f.
def test(f,myvar,myval):
return f(myvar=myval)
f = x^2
print(test(f,x,3)
It returns x^2
, but I would like 9
. Of course I don't know a priori what would be the name of the variable and f may have several variables.
The long question is that I would like to define something that plot(f,(x,xmin,xmax))
. Is there's a standard way to handle this triple (x,xmin,xmax)
? Is there's a web page for the source code for such functions to study the standard implementation?
Thanks a lot! Arnaud
