Is there a way to update an expression if the symbolic variables that it contains have been overwritten? For example,
sage: var('beta')
beta
sage: eq = x == beta
sage: beta = 1
sage: eq
x == beta
Is there a way for it to change to x == 1? I wrote the following function to do this, but I wanted to know if something similar existed already.
def update(expr):
return expr.subs(dict(zip(expr.variables(), map(lambda v:eval(str(v)), expr.variables()))))
