When the parent dies, the child should die when it's writing on the
broken pipe. At least that's how it works in Unix systems. I don't know
about Windows, however.
To let the dying be fast you should make sure that stdout in the child
is unbuffered.

You're right. Either hexadecimal should have been 0h or octal should

Yes.

I wonder how you wrote that interpreter, given that some answers are wrong.

Of course they do, but a significant portion of a Python system consists
of imported modules and these are data as far as the OS is concerned.

You can also say:
[x+y for x in range(3) for y in range(4) if x < y]
If you want to write this as a loop you have to put the for's on
separate lines separated by colons, so why not the if also? Or would you
also like to have the for's on one line?

n! I can't see why.
If you work with matrices, numpy may be interesting for you. It does
have the required functionality: M[:,0] will give you the first column.

e customary meaning of `unary' is the tally system, as a radix
system wouldn't make sense. I don't know when this term came into use
but I have known it for a long time.

woofer is much harder to follow than map, I think.
[myFunc(elt, 'booHoo') for elt in myList] is also a good candidate and
in this case I think it is preferable to both the loop and the map with
a partial or lambda in terms of clarity.
On the other hand when you just want to call a function
t in Python or whether that is to be considered strange should
depend on the availability of a floating point unit in the hardware
where the program runs? Would that make floating point numbers
"fundamentally different" from ints in the sense described above?

Numbers are immutable by nature (math). The number 3.14 remains 3.14
whatever you try to do with it. What you call an immutable number is in
fact a container that contains a number. You can change the contents of
