[Tutor] Python twitter "errors":[{"message":"Could not authenticate you", "code":32
Dear All,
I'm trying to execute the examples from
https://github.com/sixohsix/twitter with the current library version
installed by pip install (1.14.3).
#!/usr/bin/env python
# -- coding: utf-8 --
from twitter import *
con_secret='DACs' # "Consumer Secret"
con_secret_key='jold' # "Consumer Key"
token='2554' # "Access token"
token_key='HHSD' # "Access Token Secret"
t = Twitter(
auth=OAuth(token, token_key, con_secret, con_secret_key))
t.statuses.user_timeline(screen_name="RenateBergmann")
The reply is:
twitter.api.TwitterHTTPError: Twitter sent status 401 for URL:
1.1/statuses/user_timeline.json using parameters:
(oauth_consumer_key=DA...&oauth_nonce=...&oauth_signature_method=HMAC-SHA1&oauth_timestamp=&oauth_token=&oauth_version=1.0&screen_name=RenateBergmann&oauth_signature=..)
details: {"errors":[{"message":"Could not authenticate you","code":32}]}
What's the issue? Have I used the right tokens and keys? The labeling in
the script is a bit different from the Twitter api page.
Is Python 2.7 the proper version? The documentation said 2.6, but
someone told me I had to use 2.7.
Is the authentication method correct? It should be, because this is an
example from the Github readme.
I'm a beginner, so maybe it's only a slight mistake?
Thank you in advance.

Since this list is for the core language and standard library
this is a bit off list. You might get more response direct from
the author or a twitter specific mailing list(if one exists).
Failing that maybe the main Python list. However...
con_secret='DACs' # "Consumer Secret"
con_secret_key='jold' # "Consumer Key"
token='2554' # "Access token"
token_key='HHSD' # "Access Token Secret"
Example code often uses fictitious security keys.
Are you sure these values are genuine values that work if
you use them to access twitter directly?
t = Twitter(
auth=OAuth(token, token_key, con_secret, con_secret_key))
t.statuses.user_timeline(screen_name="RenateBergmann")
The reply is:
twitter.api.TwitterHTTPError: Twitter sent status 401 for URL:
1.1/statuses/user_timeline.json using parameters:
(oauth_consumer_key=DA...&oauth_nonce=...&oauth_signature_method=HMAC-SHA1&oauth_timestamp=&oauth_token=&oauth_version=1.0&screen_name=RenateBergmann&oauth_signature=..)
details: {"errors":[{"message":"Could not authenticate you","code":32}]}
What's the issue? Have I used the right tokens and keys?
Do you mean you used the same keys as in the example?
Or have you tested the keys work via some other method of access?
Is Python 2.7 the proper version? The documentation said 2.6, but
someone told me I had to use 2.7.
I doubt the differences between 2.6 and 2.7 are your problem.
Is the authentication method correct? It should be, because this is an
example from the Github readme.
I can't help there I know nothing about Twitter, far less its API!

We cannot help you unless you help us. Where does getPixel come from? What does the documentation for it say? getPixel is not a built-in Python function, and I don't believe it is a standard numpy or opencv function (although I could be wrong). So unless you tell us where getPixel comes from, we have no possible way of telling how to use it. -- Steven ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
[Tutor] Printing multi-line variables horizontally
Hello,
Python novice back again. :) I'm making progress in my learning process,
but struggling whenever attempting to creatively go beyond what's required
in the various chapter assignments. For example, there's a simple random
die roller program that looks like the following:
# Craps Roller
# Demonstrates random number generation
import random
# generate random numbers 1 - 6
die1 = random.randint(1, 6)
die2 = random.randrange(6) + 1
total = die1 + die2
print("You rolled a", die1, "and a", die2, "for a total of", total)
input("\n\nPress the enter key to exit.")
I wanted to make it a little more interesting by using ascii art
representations of the six die. When printing, however, they do so
vertically and not horizontally. Here's a snippet of the code:
die_1 = """
.-.
| |
| o |
| |
`-'"""
die_2 = """
.-.
|o|
| |
|o|
`-'"""
print(die_1, die_2)
So, how would I get this to display horizontally?
Like so...
.-. .-.
| | |o|
| o | | |
| | |o|
`-' `-'
Thanks,
Greg

This isn't so easy because as you print the first die, your cursor
ends up at the bottom of its display.
There is a module called curses which lets you manipulate the
terminal. It has functions to get the x,y position on the screen, and
to set it (i. e. move the cursor). You might want to play with that.
If you want to get your feet wet with unicode, you could use the dice
characters (see: http://www.unicode.org/charts/PDF/U2600.pdf).
>>> dice_1 = '\u2680'
>>> print (dice_1)
⚀
>>> print (dice_1, dice_2)
⚀ ⚁
They are pretty small.

What I mean is that it looks like each "die" has the same number of lines, and each line is the same width. Is that assumption correct? If so, then that might simplify matters for you. It sounds like you're trying to build a "row" of dice. To do so, you might be able to loop over the lines of both dice at once to get the composite image. That is: row[0] = die_1_lines[0] + die_2_lines[0] row[1] = die_1_lines[1] + die_2_lines[1] ... where we take horizontal slices of each dice and stick them side by side. To make this work, we need to be able to get at individual lines. To break a string into a list of lines, see https://docs.python.org/2/library/stdtypes.html#str.splitlines ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

Does this http://code.activestate.com/recipes/473893-sudoku-solver/ help
at all, especially the show function right at the top?

There is a module called curses which lets you manipulate the
terminal. It has functions to get the x,y position on the screen, and
to set it (i. e. move the cursor). You might want to play with that.
The Python curses module is *nix only but see this
https://pypi.python.org/pypi/UniCurses/1.2 as an alternative for other
platforms.

[Tutor] Pigs can fly?
Hi everyone, I'm curious if anyone has encountered: http://codegolf.stackexchange.com/questions/35623/are-pigs-able-to-fly As soon as I saw this problem, I felt strongly compelled to play with this. :P Of course, I can't show any solutions, but I thought the problem might be interesting to others here. Even without the code minimization constraints due to "code golf" I still think it's a worthwhile problem to work out. It's one of those problems that exercises multiple skills for the intermediate Python programmer, such as input/output, parsing, knowing your data structures, and writing good test cases. And it makes a good case that interesting and fun problems can be mathematical, and yet have nothing to do with basic arithmetic. What's really being asked in the problem is a graph traversal in disguise. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

Nice question! I recommend that you try to solve the problem yourself,
if you can, but once you've given it a good solid try, you can have a
look at my solution and see if you can understand it. Feel free to ask
