Hi, perl has __END__ which ignore all the lines below it.
Is there anything similar to __END__ in python? Thanks.

It does beg the question of what an identity function is, though.
Thankfully, Paul answered that question with a good explanation*.
Thanks, everyone, for the discussion.

It should be clear from the rest of the thread. But, to be explicit:
That's not what is meant by “identity function”, and the Python ‘id’
function is not an identity function.
The Python ‘id’

These seem good to me. One argument given, the same result returned.

I don't see why this last case should hold. Why does the function
take more than one argument? And if it does,

There is a built-in identity function in Python. The function is called
'id'. See https://docs.python.org/3/library/functions.html#id Note that
this will not behave the same across different Python runtimes. e.g.
CPython, IronPython or Jython all implement this differently.
An example:
Python 3.5

I don't see why this last case should hold. Why does the function take more
than one argument? And if it does, then
why doesn't it work like this?
