parse_expr for Abs(-1)

[Victor Kam]

I have an expression, something as simple as |-1|, i.e. Abs(-1).  I don't want it to evaluate to its value, i.e. 1, for printing reasons. I tried:

parse_expr("Abs(-1)", evaluate=False)

But it gives me the evaluated expression anyway.  In fact, I can't figure out how to get the expression tree to just keep this Abs function with its argument.

So if I want it to display |-1| but not its value, how would I go about doing it?  Thanks.

Hi

Abs(-1, evaluate=False) will stay without evaluating itself.
