Which version of Python are you using? The raw_input call is very
Python 2, but you're using print as a function, and then you're
converting input()'s result to an integer, both of which suggest
Python 3.x. If you're using Python 2, do NOT use input() - it is
dangerous, deceptively so. In Python 3, that problem no longer
applies.

if you need to be checking individual digits you are probably best
keeping the input & number to be checked as strings.

it would then be a trivial task to expand this program to work with words
as well as numbers.

remember that strings are a sequence.
they can be used as iterators & sliced in the same way as lists & tuples.

you will probably learn more through trial & error than you will from
being given an answer

to shine some more light on my advise try the following

code="7689"
for digit in code:
print(digit)

does this give you any Ideas on how to proceed?

I wont provide the code but i will try to break the problem down into
simple steps (this is the most important skill to develop in programming)


set the number to be guessed
get the user input
step through each digit in the input
compare to the co-responding digit in the number to be guessed
generate the required output

actually let me just expand on my earlier teaser code

does this switch on any light-bulbs for you

data='7865'
guess=input('guess')
for key,digit in enumerate(data):
print digit,guess[key]

I just want to add that this programming exercise, while pretty
common, stinks.

A new programmer shouldn't be embroiled in the morass of
interactive programming.

While this is true for some people sometimes, I don't think
it is always true. Very often it is easier and faster to
learn something be seeing a worked out example and studying
it to see how it works. This is especially true when one
is new to a programming language and doesn't have a good
understanding of the terminology and concepts that people
who have been using the language take for granted.

Robert, please see if this is what you were trying to do:

-------------------------
guessesTaken = 0 #This is a "Guesses taken counter"
print("Hello, what's your name?") #Asking the user to input their name
N = input() #What the user's name is
import random #This is importing the random function
number = random.randint(1, 999) #This tells the random function to generate a random number between 1 to 1000

number_str = str (number) # Convert 'guess' to a string of digits.
while len (number_str) < 3: # If there are less than 3 digits, add leading "0"s until it is three digits.
number_str = "0" + number_str

print(N + ", I'm thinking of a number between 1-1000") #Not needed but tells the user their name and tells them that it's thinking of a number betweeen 1 to 1000

while guessesTaken < 10:
print('Take a guess.')

guess = input()
guess = int(guess)

guessesTaken = guessesTaken + 1
if guess < number: #Says that if the guess is too low it will print a message saying that the guess is too low
print('Your guess is too low.')
if guess > number: #Says that if the guess is too high it will print a message saying that the guess is too high
print('Your guess is too high.')
if guess == number:
break #Breaks the loop, meaning it will continue to loop for 10 times while giving them messages from above depending on their results

guess_str = str (guess) # Convert 'guess' to a string of digits.
while len (guess_str) < 3: # If there are less than 3 digits, add leading "0"s until it is three digits.
guess_str = "0" + guess_str
if len (guess_str) > 3: guess_str = guess_str[-2:] # Make sure it is no longer than 3 digits.
# Here, we know that 'number_str' is exactly 3 digits. 'guess_str' is at least
# 3 digits but could be more if the user entered, for example, 34567.
print ("digits matched: ", end='')
for i in range (2, -1, -1):
# 'i' will have the values, 2, 1, 0.
if guess_str[i] == number_str[i]: print ("Y", end='')
else: print ("N", end='')
print()

if guess == number:
guessesTaken = str(guessesTaken)
print("Congrat's, " + N + "! You managed to get the number in " + guessesTaken + " guesses!") #Tells the user they managed to guess it in x number of times
if guess != number: #If the user is unable to guess the number in 10 times it will stop the loop and give the user a message
number = str(number)
print("No, the right number was" + number)
-------------------------

Some comments...
guess_str[-2:]
you want to read about "slices" in the Python docs, for example
http://docs.python.org/2/tutorial/introduction.html#strings
The -2 means indexing starts counting from the right end of the string
rather than the left had the index been positive.

print ("Y", end='')
The end='' means don't print a newline after printing the "Y" string.
See http://docs.python.org/2/library/functions.html#print

Also, what Mark and Rusi were trying to say (not very clearly)
is that when you post from Google Groups, Google Groups insert
a lot of empty lines in the ">" the at the top of the message.

Look at your message,
https://groups.google.com/d/msg/comp.lang.python/6WMfzbtIyi8/AV4sce1zPicJ
(make sure to click the "- show quoted text -" link!)
to see what everybody who doesn't use Google Groups sees.

When post a message, please try to edit you message before
you send it to get rid of those blank lines. In most cases
you can get rid of all the ">" text, *except* for a small
amount that gives the gist of what you are responding to.

Cheers to that!
If the 'print' statement were called a 'debug' statement, then it would be more clear that a clean and correct program should have no debug (ie print) statements.

So from the most recent post do you infer that your explanations were successful in creating some understanding?

"...an error, something about the 'end'" is not much to go on. :-)

Most of the time, when there is an error in a python program,
Python will print "traceback" error message. When asking for
help please copy and paste those lines in your post. Without
that it is just a guessing game for anyone to try and figure
out what is wrong.

Did perhaps your traceback message look like this?

File "xx3.py", line 28

print ("digits matched: ", end='')

^

If so, you are running your program with python2, not python3.
So you need to either figure out how to run python3 (does entering
the command "python3" do anything?) or change the program to work
with python2.

If the error message was different than above, you need to post
it here if people are to have any chance of helping you figure
out what is wrong.

Why did you add those two >> symbols in front of your new text? Each
such symbol is supposed to indicate that another level of quoting is
occuring. So when I saw your message, I first concluded that you sent a
blank reply.

(I also added another character in front of it, so you'd see it.
Apparently googlegroups messes up your view of things in order to cover
up its bugs in posting.

As for your question. Yes, you did something wrong. You thoroughly
underspecified the phrase "not working."

When you run a program and it gets an exception, read the whole
traceback. And when you want help here, copy the WHOLE TRACEBACk.

If raw_input() is working without an exception, then you are NOT running
Python3.x. Figure that out first, perhaps by sticking these two lines
at the beginning of your code:

import sys
print(sys.version)

Sure it's possible. What do you think would happen if you
replaced the code that compares the digits and prints Y or
N with with something like this?

if guess_str[i] > number_str[i]: print ("H", end='')
if guess_str[i] < number_str[i]: print ("L", end='')

if guess_str[i] == number_str[i]: print ("Y", end='')

(you are comparing 1-character long strings containing a
digit between "0" and "9" but they will compare the same
way numbers do.)

To do that, you'll need to convert the string digits back to
numbers that you can do arithmetic on. The int() function
can do that. Then you can do something like

if guess_num > number_num + 3: ... print what you want here.

You'll find you get more and better answers to your questions
if you attempt to do something yourself and when you find it is
not doing what you want, post here saying what you tried, what
it did, and how what it did is different from what you want.

You'll also get better responses if you edit out the empty
and excess ">" lines in the quoted text of your replies,
which you are still not doing.

No, you're still adding a ">" character before the stuff you typed.
That's supposed to show what you are quoting. One bracket is the person
you're replying to, two marks the stuff he was quoting, and so on.

Any decent mail program does it for you automatically, or with minimum

Only googlegroups messes it up so consistently.
