dedent if so it lines up with else below
n = n/2
else:

Once you get indents consistent, test failure should suggest the

For example, The Borribles by De Larrabeiti is one of my favorite books despite my knowing virtually nothing of the back-streets of London or the (now dated) pop-culture satire it contained. Many of the main villains in the book are hilarious and mean-spirited parodies of a series of British children's literature, The Wombles, and a British TV show, Steptoe and Son, but the characters work fine on their own. But even so, I agree that a footnote is a good idea. And I haven't always lived up to that ideal, myself. -- Neil Cerutti -- https://mail.python.org/mailman/listinfo/python-list

Yeah, that's definitely the best way to do it. You don't need to know The Beauty Stone to understand that Colinette, in the city of Lenalede, is trying to get herself appointed as Lord Chief Justice on the grounds that (she claims) the current incumbent is unfair in his rulings. But if you _do_ know that obscure 19th century opera, you'll know there's a line in it "And Colinette from Lenalede, who counts herself the fairest there". (The opera has absolutely nothing to do with justice, incidentally. Colinette is entering herself in a beauty contest. Quite a different meaning of "fairest".)

One of the (occasionally humbling) effects of internet communication is the realisation that the pop-culture reference you assumed would be instantly shared and understood by *any normal person anywhere* is, in fact, confined to your own back yard. You may or may not have caught sight of the BBC's recent blanket marketing of the upcoming 50th anniversary of Dr Who, a somewhat iconic British TV series. I was genuinely perplexed when US-based websites started running articles like "What the *** is this Dr Who all about?" and "All you need to know about Dr Who: a Guide for the Unknowing". Here in Britain, even if you've never watched and/or hate the thing, you can't help at least knowing *something* about Dr Who. At least the basics: Doctor, TARDIS, Daleks; that sort of thing. In reverse, I'm sometimes bemused by (often, but not always) references to things which apparently sit centrally in the American pop-culture psyche but which are unknown over here, or at least simply known *about*. It's not usually a problem -- it's always fun to gain a bit of an insight into some other culture. Just occasionally, though, someone says, eg, "You keep using that word; I don't think it means what you think it means", intending it as a humorous reference to "The Princess Bride". But if you have (as I strongly suspect 99% of the world's population has) no knowledge of that film, or at least of its catchphrases, then it can come across instead as a slightly blunt admonition of someone else's ignorance. (Of course, if some were to say "My name is Inigo Montoya; you killed my father; prepare to die" without any further comment then you'd either have to assume that they were making a reference to a film or book unknown to you or that someone going by that alias genuinely believed you were responsible and had tracked you down across the internet to confront you finally on comp.lang.python.

I fully support the right of everyone to make cryptic references to movies, television shows, science fiction and fantasy novels, internet memes, and assorted pop culture references. Offler knows I've done it myself. But, if the reference falls flat, or worse is misunderstood, and sometimes they will, can I suggest there are two appropriate responses? 1) Sheepish apology for making a reference too obscure, e.g.: Oh, sorry, I was quoting Captain Mainwearing's catchphrase from "Dad's Army", it isn't intended to imply that Alister is an actual goose-stepping fascist who believes a lot of racial pseudo-scientific rubbish. 2) Incredulity that anyone might have missed the reference, e.g.: What? How can anyone not recognise that reference? Everyone I know in the UK over the age of 60 loves the show "Dad's Army"! This is one of the funniest lines from it! Oh how me dear ol' mum used to laugh every time Captain Mainwearing said it! (Listen very carefully, I shall say this only once.

Also even if you change this to count instead of print, it could be very inefficient for large values of x. If x is greater than a*b*c, find how many numbers up to a*b*c are not divisible by a, b, or c. (Depending on your interpretation of the English language for 2, 3, 5 this is either 8 or 1, you could check whether the system is set to Australian English to determine the correct action here.) You may then store these numbers in a list for easy reference. Now the answer you want is the length of that list times the integer part of x divided by a*b*c plus the number of values in the list that are less than the remainder you get when dividing x by a*b*c. If x is less than a*b*c then just find how many numbers up to x are not divisible by a, b, or c, which would be a case of re-using some of the above code. For extra credit, calculate and use the least common multiple of a,b and c instead of just using their product. -- Duncan Booth -- https://mail.python.org/mailman/listinfo/python-list

Have your friend start by writing down how she or he would solve this
problem by hand. I'll get you started by solving the problem for 7.
Positive integers less than 23 are 1, 2, 3, 4, 5, 6. So let's start
checking them for divisors:
- 1 is not divisible by 2, 3 or 5, so we count one number.
- 2 is divisible by 2, but not by 3 or 5, so we count two numbers.
- 3 is not divisible by 2, so we count three numbers.
- 4 is divisible by 2, but not 3 or 5, so we count four numbers
- 5 is not divisible by 2, so we count five numbers.
- 6 is divisible by 2 and 3, but not by 5, so we count six numbers.
And the answer is: 6.
Now that you know what you yourself would do to solve this problem, the
next step is to write it in terms that a computer can understand. A few
hints:
1) You can check divisibility by using the % operator, which returns the
remainder after division. So 36 % 6 gives 0, which means that 36 is
divisible by 6. 37 % 6 gives 1, which means 37 is not divisible by 6.
2) You can use "for i in range(1, N)" to generate the positive integers
less than N.
3) You can use the "or" operator to efficiently check multiple
conditions. For example, this line of code:
if (a % 2) or (a > 16):
checks whether a number a is either an odd number or larger than sixteen,
and if so runs the indented block of code following (not shown).
4) You can prompt the user for a value using the input (Python 3) or
raw_input (Python 2) function. For example, using Python 2:
result = raw_input("Enter a number between 3 and 12: ")
lets the user type in anything in response. That result will be a string,
to convert it to a number:
result = int(result)
5) You can create a variable and initialise it to some value like this:
count = 0
creates a variable called "count", set to the value 0. You can then add
one to it like this:
count = count + 1
or if you prefer:
count += 1
Either way adds one to count.
I expect that the above should be enough to get your friend started and
possibly even finished. If she/he gets stuck, come back with some code
and specific questions.
Good luck!

First of all there seems to be two problems, not 1.
Here are some steps for each of the calculations. Any resemblance of
these steps to actual program code is due to my not bothering to
obfuscate the statement and function names more than I did.
1) Find all the numbers less than n that are not divisible by a, b, or c.
ask the user for x;
assign the value 0 to some other variable i;
while i is not greater than than x do the following [
if i is not divisible by a and i is not divisible by b and i is not
divisible by c then display i to the user;
add 1 to i;
]
2) Find the collatz sequence for x.
ask the user for initial x;
while x is not 1 {
if x is divisible by 2 [ new x = perform even number collatz math on x; ]
otherwise [ new x = perform odd number collatz math on x; ]
display new x to the user;
}
