Quickly recalling the definition of a temporary function to make minor edits?
Suppose you're working with the sage console primarily as a calculator, and define some temporary shorthand function, such as,
sage: R = GF(751)
sage: def f(x):
....: return R(x^3-x+188)
After I've used this f
several times, I may want to change the output to something similar, like x^3-x+376
. Is there a quick way to recall the definition of f
within the console so that I can edit in the minor change, instead of having to define a new function?
