You'll have to explain more about your problem.  What, exactly, is wrong?

If, as you say, the input and output is correct, then why do you say there
is a problem?

Please post your code in and the problem in your message. Here it

This is a ridiculous abbreviation scheme, but for purposes of
your project that doesn't matter.

No, your program outputs nothing. That's bound to fail. ;)

How is your program supposed to work, in your own words?

I just dont understand what is wrong, seriously. I mean. They said:

"..if its length is strictly more than 10 characters. All too long words should be replaced with a special abbreviation."

and:
"... This abbreviation is made like this: we write down the first and the last letter of a word and between them we write the number of letters between the first and the last letters. That number is in decimal system and doesn't contain any leading zeroes."

I solved it with my:

xList = list(x) 

    if len(xList) > 4: 
        print(xList[0], int(k), xList[j], sep='', end='') 
    else: 
        print(x)

really, i dont know why.. :(

How about because you do a system exit on the first line of their 
input? The one that's all digits. And even if you get past that, you 
only process one of their words.

	First off -- there is no need to turn the "word" into a list of
characters... You can index strings. x[0] is the first character, x[-1] is
the last.

	Second... k is already an integer, so there is no need to convert it
into an integer.

	Third... i, j, k aren't really needed -- for something this simple

	if not x.isdigit() and len(x) > 4:
		print ("%s%s%s" % (x[0], len(x)-2, x[-1])
	else:
		print (x)

    else: 
        print(x)

Your first problem is that input() returns text only up the a
newline, and then stops.

So you are reading the initial number line, but never reading the
rest of the lines.

Well,
i've changed the "if len(xList).." from 4 to 10

But still, it is not accepted :(

Where is your code that meets these requirements?

Input
The first line contains an integer n (1?=?n?=?100). Each of the
following n lines contains one word. All the words consist of
lowercase Latin letters and possess the lengths of from 1 to
100 characters.

Output
Print n lines. The i-th line should contain the result of
replacing of the i-th word from the input data

I suggest you take your problem one step at a time, like this:

1. You need to convert a string like "localization" to "l10n"
Write a function that takes strings like "localization" and RETURNS strings
like "l10n". The function SHOULD NOT use print.

2. Now you need to convert a list of strings like
["word", "localization", "internationalization",
"pneumonoultramicroscopicsilicovolcanoconiosis" ]
to a list like
["word", "l10n", "i18n", "p43s"]
You can use the above function (1). NO PRINTS

3. Use the function in 2 above to solve the problem.
Here you may use print

That's not a problem, it's a url.

That's not source code, it's a url.

As my newsreader isn't a web browser, I can't help. Sorry.
