THIS IS THE MAGIC OF EVAL FUNCTION.

Answer 1

nice.
you can also do this using JavaScript:
alert(eval(prompt()));

beware that improper handling of eval may result in huge security holes.

Answer 3

I know seamiki this is only for fun

Answer 4

you could also do this with a single-liner like this
print(eval(input()))

Answer 5

Nice, but I think you are missing the last closing bracket on the first line

Answer 6

All you are doing is using an abstracted function. Means what you are doing is not ACTUALLY a one-liner. It is just calling another multi-liner function which is predefined.

Answer 7

can somebody explain me how it works?
