[Tutor] os.getcwd() confusion
G'day,
I have a comprehension issue here! I have made two simple scripts:
## script1
import os
print os.getcwd()
-
## script 2
import os
f = open('test', 'wb')
f.write(os.getcwd())
f.close()
_
Both scripts are in my home directory.
Using bash I cd to some other directory and call script 1:
> python ../../script1.py
and I get this result printed to the screen:
> users/scriptdir/dir1/dir2
i.e. the script returns the name of the directory that I'm currently
working in.
However if I call script2:
> python ../../script2.py
I get a result that to me seems inconsistent: the script writes the
directory
that IT is in (i.e., NOT the name of the directory I'm currently working
in),
to the file 'test' in the home directory.
I don't quite understand what is happening here! Any explanation would be
much appreciated.
Cheers,
CSS

As Oscar says you are invoking your script with Python 2. Python 2's input()
function evals user input as a Python expression. For example if you run a
script
print input("your input please: ")
and you type
1 + 1
the script will print
2
Likewise if you type
Rafael
the script will look up the value of a variable named Rafael. This doesn't
exist and therefore you get an exception.
But this is all a distraction -- how exactly are you invoking what you think
is Python 3.3.0? What is your operating system?
If you are using Linux or OSX open a terminal window and try to run your
script from that terminal window with
python3.3 ~/Documents/3_Tufcik.py

Based on the error you show, I doubt that very much.
As for the HTML ... I copied the code from the Python Shell - should I post

Would that resolve that issue you mentioned?
No. It has nothing to do with the Python shell, it has to do with your email
program.
Your email program will probably have an option somewhere to send "Rich Text" or "Styled
Text" or "HTML Text". Turn it off. There are many reasons to avoid it, but as far as this
mailing list goes, the main one is that it mangles the code you send and makes it harder to answer your
questions.
"Rafael" is the user's in put, and that value is assigned to the variable
"name".
I made sure only a string is accepted as input
name = (str(input("What's your name?"))
The call to str() is unnecessary.
In Python 3, this works as you would expect:
# Python 3.3
py> name = input("What's your name? ")
What's your name? Raphael
py> print(name)
Raphael
But when you run it, that's not the result you get. You get this result:
# Python 2.7
py> name = input("What's your name? ")
What's your name? Raphael
Traceback (most recent call last):
File "", line 1, in
File "", line 1, in
NameError: name 'Raphael' is not defined
This tells me very strongly that you are actually using Python 2, not Python 3.
Try this: at the very beginning of your file 3_Tufcik.py, put these two lines:
import sys
print(sys.version)
then run the file as you would normally, and see what it prints.

Re: [Tutor] Beginner level: Why doesn't my code work?
Hello, please post in plain text (not html) in future. Also you should

this case.
Thank you, I am using Python 3.3.0
As for the HTML ... I copied the code from the Python Shell - should I post

In Python 3 you should use input(). In Python 2 you should use
raw_input(). I'm guessing that you're using Python 2. In Python 2 the
input() function tries to evaluate whatever the user types in as if it
was Python code. Since Rafael is not a defined variable it fails. The
fix is to use raw_input() which just returns a string.
I am not sure I understand.
"Rafael" is the user's in put, and that value is assigned to the variable
"name".
I made sure only a string is accepted as input
name = (str(input("What's your name?"))
Can you clarify? Thank you in advance.

For the benefit of others,I believe the full class (from the Django

class Poll(models.Model):
question = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
def was_published_recently(self):
return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
#
was_published_recently.admin_order_field = 'pub_date'
was_published_recently.boolean = True
was_published_recently.short_description = 'Published recently?'

In Python 3 you should use input(). In Python 2 you should use
raw_input(). I'm guessing that you're using Python 2. In Python 2 the
input() function tries to evaluate whatever the user types in as if it
was Python code. Since Rafael is not a defined variable it fails. The
fix is to use raw_input() which just returns a string.
An alternative fix is to write
input = raw_input
at the top of your script. That way you won't need to change anything
else to have it work with Python 3. In fact if you write it like this
try:
input = raw_input
except NameError:
pass
then it will work in both Python 2 and 3.

For example, see line 586 in admin/options.py:
https://github.com/django/django/blob/1.5.1/django/contrib/admin/options.py#L586
# Gather actions from the admin site first
for (name, func) in self.admin_site.actions:
description = getattr(func, 'short_description',
name.replace('_', ' '))
actions.append((func, name, description))
The default description is the name with underscores removed, unless
you set a custom description in the function's "short_description"
attribute. I'm not experienced with Django, so I can't ramble off lots
of examples, but hopefully you get the gist.

Thanks guys i had no idea about these method attributes and also these underlying oop __objects__ @ eryksun i understand your explanation, im still having trouble figuring out how django is being used in the tutorial. class Poll(models.Model): # ... def was_published_recently(self): return self.pub_date >= timezone.now() - datetime.timedelta(days=1) was_published_recently.admin_order_field = 'pub_date' was_published_recently.boolean = True was_published_recently.short_description = 'Published recently?' list_filter = ['pub_date'] search_fields = ['question'] date_hierarchy = 'pub_date' if you look at the diagram under that function, why is the value of "was_published_recently.short_description" the title of that field? replacing the old title? is a "short_desccription" attribute set somewhere in django being inactive, but once you make use of this attribute(or keyword), whatever the value is automatically becomes the field title? is it the same for boolean being the value of the field with the checked or unchecked symbol? ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

You mean you are using Python 3? The replacement for urllib2 in Python 3 is
urllib.request and a few others. There is a tool called 2to3 that can help
you with the transition.
The original Python 2 code:
$ cat parse.py
import urllib2
import json
url = "http://*/goldencasket";
s = urllib2.urlopen(url).read()
s = s.partition("latestResults_productResults")[2].lstrip(" =")
s = s.partition(";")[0]
data = json.loads(s)
lotto = data["GoldLottoSaturday"]
print lotto["drawDayDateNumber"]
print map(int, lotto["primaryNumbers"])
print map(int, lotto["secondaryNumbers"])
$ python parse.py
Sat 18/May/13, Draw 3321
[14, 31, 16, 25, 6, 3]
[9, 35]
Now let's apply 2to3 (I'm using the version that comes with python3.3).
The -w option tells the script to overwrite the original source:
$ 2to3-3.3 parse.py -w
[noisy output omitted]
The script now looks like this:
$ cat parse.py
import urllib.request, urllib.error, urllib.parse
import json
url = "http://*/goldencasket";
s = urllib.request.urlopen(url).read()
s = s.partition("latestResults_productResults")[2].lstrip(" =")
s = s.partition(";")[0]
data = json.loads(s)
lotto = data["GoldLottoSaturday"]
print(lotto["drawDayDateNumber"])
print(list(map(int, lotto["primaryNumbers"])))
print(list(map(int, lotto["secondaryNumbers"])))
$ python3.3 parse.py
Traceback (most recent call last):
File "parse.py", line 7, in
s = s.partition("latestResults_productResults")[2].lstrip(" =")
TypeError: expected bytes, bytearray or buffer compatible object
After manually changing the line
s = urllib.request.urlopen(url).read()
to
s = urllib.request.urlopen(url).read().decode()
$ python3.3 parse.py
Sat 18/May/13, Draw 3321
[14, 31, 16, 25, 6, 3]
[9, 35]

Putting packages directly in the standard Lib isn't a good idea. Even
the main Lib/site-packages should be reserved for installed packages
(i.e. setup.py, pip, exe/msi). Use the environment variable PYTHONPATH
to add your own list of directories to sys.path. For NT the list is
delimited by a semicolon.

Those directories are already on sys.path. By the way Python's
sys.path for importing modules/packages isn't related to the PATH
environment variable. NT uses PATH to find and open files and DLLs,
e.g. to find python.exe, python33.dll, and your .py scripts run from
the command line.

Python does use NT's registry (either HKLM or HKCU, depending on how
you installed) for some for some of the base paths, but don't mess
with this:
C:\>reg query hklm\software\python\pythoncore\2.7\PythonPath
HKEY_LOCAL_MACHINE\software\python\pythoncore\2.7\PythonPath
(Default)REG_SZ
C:\Python27\Lib;C:\Python27\DLLs;C:\Python27\Lib\lib-tk
C:\>reg query hklm\software\python\pythoncore\3.3\PythonPath
HKEY_LOCAL_MACHINE\software\python\pythoncore\3.3\PythonPath
(Default)REG_SZC:\Python33\Lib;C:\Python33\DLLs
Alternatively you can use your user profile site-packages. On NT, this
defaults to "{userbase}/Python{py_version_nodot}/site-packages", where
userbase is "%appdata%\Python". You can change the latter by setting
the environment variable PYTHONUSERBASE. Check your current setup as
follows:
userbase = sysconfig.get_config_var('userbase')
usersite = sysconfig.get_path('purelib', '%s_user' % os.name)
This is the directory pip uses if you install --user.
