It can be differentiated, but no way to solve(== find break monotony
points). So I'm about using numeric diff. Is there any implented
I wonder if we had a Hold class that takes arguments (class, args) that
prints as class(*args, evaluate=False) might be a way to go and then have a
`touch` or `release` function that converts Hold to class(*args) might be a
way to go.
Hold(Add, 3, 4)
3 + 4
touch(_)

Hello everyone,
I'm an undergraduate at BITS Pilani Goa Campus. I was going through the
project ideas for last year and there was an idea under the physics part,
about the implementation of the known analytical solutions to quantum
models .(This is the idea I am talking about :
I have taken up this issue of replacing assert with raising exceptions in
certain segments of the code. I have done part of the job.
