This question might be a bit of an overstretch, or really obvious, but I haven't been able to find an answer yet.



Is there a way to automatically view the minimum required arguments for a WL function? For example, Sin only requires 1 argument, while Replace requires both an expression and the list of rules. Is there a way that, for example, I can input Sin into a function, and get back something like Real, or enter Replace, and get back Expression, Rules?



I hope this makes sense - I would like to be able to automate input to any function in Mathematica, by being given the required arguments.



Thanks!

    Is there a way to automatically view the minimum You might be able to parse it out from the output of Information[functionName], It will list all the different signatures of the function there, one per line.

  • That's a good idea, however, when I try val = Information[Replace], and then view the results with ?val, it returns that val = Null

    @Jmeeks29ig Information has side effects and doesn't return anything. Fortunately we can scrape the side effects with Block[CellPrint = Sow, Reap[Information[Replace]][[-1, 1]]]. However Replace::usage would be an easier way to see the information your after.

You can use SyntaxInformation:

One-line joke

A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
