The number 945 is the characters 'α' ordinal value in the unicode charset
correct?
Yes, the unicode character set is just a big list of characters. The
946th character in that list (starting from 0) happens to be 'α'.
The command in the python interactive session to show me how many bytes
this character will take upon encoding to utf-8 is:
s = 'α'
s.encode('utf-8')
b'\xce\xb1'
I see that the encoding of this char takes 2 bytes. But why two exactly?
That's how the encoding is designed. Haven't you read the wikipedia
article which was already mentioned several times?
How do i calculate how many bits are needed to store this char into bytes?
You need to understand how UTF-8 works. Read the wikipedia article.
Trying to to the same here but it gave me no bytes back.
s = 'a'
s.encode('utf-8')
b'a'
The encode method returns a byte object. It's length will tell you how
many bytes there are:
>>> len(b'a')
1
>>> len(b'\xce\xb1')
2
The python interpreter will represent all values below 256 as ASCII
characters if they are printable:
>>> ord(b'a')
97
>>> hex(97)
'0x61'
>>> b'\x61' == b'a'
True
The Python designers have decided to use b'a' instead of b'\x61'.
py> c.encode('utf-8')
b'\xce\xb1'
2 bytes here. why 2?
Same as your first question.
py> c.encode('utf-16be')
b'\x03\xb1'
2 byets here also. but why 3 different bytes? the ordinal value of
char 'a' is the same in unicode. the encodign system just takes the
ordinal value end encode, but sinc eit uses 2 bytes should these 2 bytes
be the same?
'utf-16be' is a different encoding scheme, thus it uses other rules to
determine how each character is translated into a byte sequence.
py> c.encode('iso-8859-7')
b'\xe1'
And also does '\x' means that the value is being respresented in hex way?
and when i bin(6) i see '0b101'
I should expect to see 8 bits of 1s and 0's. what the 'b' is tryign to say?
'\x' is an escape sequence and means that the following two characters
should be interpreted as a number in hexadecimal notation (see also the
table of allowed escape sequences:
http://docs.python.org/3/reference/lexical_analysis.html#string-and-bytes-literals
).
'0b' tells you that the number is printed in binary notation.
Leading zeros are usually discarded when a number is printed:
>>> bin(70)
'0b1000110'
>>> 0b100110 == 0b00100110
True
>>> 0b100110 == 0b00100110
True
It's the same with decimal notation. You wouldn't say 00123 is different
from 123, would you?

No, here it stands for bytes:
http://docs.python.org/3/reference/lexical_analysis.html#string-and-bytes-literals
b'\xce\xb1' = we are looking at a byte in a hexadecimal format?
No, b'\xce\xb1' represents a byte object containing 2 bytes.
Yes, each byte is represented in hexadecimal format.
if yes how could we see it in binary and decimal represenation?
>>> s = b'\xce\xb1'
>>> s[0]
206
>>> bin(s[0])
'0b11001110'
>>> s[1]
177
>>> bin(s[1])
'0b10110001'
A byte object is a sequence of bytes (= integer values) and support
indexing.
http://docs.python.org/3/library/stdtypes.html#bytes
Since 2^8 = 256, utf-8 should store the first 256 chars of unicode
charset using 1 byte.
Also Since 2^16 = 65535, utf-8 should store the first 65535 chars of
unicode charset using 2 bytes and so on.
But i know that this is not the case. But i dont understand why.
Because your method doesn't work.
If you use all possible 256 bit-combinations to represent a valid
character, how do you decide where to stop in a sequence of bytes?
s = 'a'
s.encode('utf-8')
> b'a'
utf-8 takes ASCII as it is, as 1 byte. They are the same
EBCDIC and ASCII and Unicode are charactet sets, correct?
iso-8859-1, iso-8859-7, utf-8, utf-16, utf-32 and so on are encoding methods,
right?
Look at http://www.unicode.org/glossary/ for an explanation of all the
terms.

How often do we need to tell you that you should reread your posts

You start with telling us you have problems with "month" and then show
us code regarding "year"
So, i must tell:
for i, month in enumerate(months):
print(' %s ' % (i, month) )
to somehow return '==' instead of 0 but don't know how.
As with most of your problems you are barking up the wrong tree.
Why not use the actual value you get from the form to check whether you
have a valid month?
Do you understand why "0" is submitted instead of "=="?

To get the header row you could do something like:
header_row = table.find(lambda tag: tag.td.string == "NYSE")
From there you can look for the next row you are interested in:
advances_row = header_row.findNextSibling(lambda tag: tag.td.string ==
"Advances")
You could also iterate through all next siblings of the header_row:
for row in header_row.findNextSiblings("tr"):

The last element in your "words" list will still have a newline
character appended to it.
You could probably use line.split().
See also the docs:

for i, word in enumerate(words):
if len(word.strip(punctuation)) > 3:
# Capitalise and replace words longer than 3 (without

# Join the capitalised words with spaces.
lines.append(' '.join(words))
This rebuilds the line including a newline character at the end.
# Join the capitalised lines by the line separator
capitalised = linesep.join(lines)
Because you haven't removed the newline character from each line,
joining them with "linesep" introduces a second newline character after
each line.

In January, "random joe" noticed the same problem[1].
I think, Anssi Saari[2] was right in saying that there is something
wrong in the browser or server setup, because I notice the same
behaviour with Firefox, Chromium, wget and curl.
$ ll *July*

-rw-rw-r-- 1 andreas andreas 748041 Aug 2 03:27 wget_2012-July.txt.gz
The browsers get a double gzipped file (size 747850) whereas the
download utilities get a normal gzipped file (size 748041).
After looking at the HTTP request and response headers I've noticed that
the browsers accept compressed data ("Accept-Encoding: gzip, deflate")
whereas wget/curl by default don't. After adding that header to
wget/curl they get the same double gzipped file as the browsers do:
$ ll *July*
-rw-rw-r-- 1 andreas andreas 747850 Aug 27 13:48 chromium_2012-July.txt.gz

-rw-rw-r-- 1 andreas andreas 747850 Aug 2 03:27
wget_encoding_2012-July.txt.gz
I think the following is happening:
If you send the "Accept-Encoding: gzip, deflate"-header, the server will
gzip the file a second time (which is arguably unnecessary) and responds
with "Content-Encoding: gzip" and "Content-Type: application/x-gzip"
(which is IMHO correct according to RFC2616/14.11 and 14.17[3]).
But because many servers apparently don't set correct headers, the
default behaviour of most browsers nowadays is to ignore the
content-encoding for gzip files (application/x-gzip - see bug report for
firefox[4] and chromium[5]) and don't uncompress the outer layer,
leading to a double gzipped file in this case.

Quite odd. According to the latest version on Github, "PDFTextExtractionNotAllowed" was moved into the "PDFPage" class, but the sample code in the docs was obviously not updated. https://github.com/euske/pdfminer/blob/master/pdfminer/pdfpage.py So just leave out that line and if you need that exception use "PDFPage.PDFTextExtractionNotAllowed" instead of "PDFTextExtractionNotAllowed".

This datetime field is formatted as follows: %m/%d/%Y

The trouble comes from the fact that I need to insert this value into
mySQL. Doing it directly gives me an error: "Incorrect formatting".
After a bit of googling and trial I found out that mySQL is looking
for the format of '%Y/%m/%d %H:%M:%S.{milliseconds}.
There is a mySQL function which transfers the data into the proper
format: STR_TO_DATE(), but I can't obviously call it since it is not
known to Python.
You don't want to call "STR_TO_DATE()" from Python but use it inside the
SQL statement.
So instead of doing the conversion in Python as Mark suggested, you
could do something like
sql_stmt = """INSERT ...
VALUES (..., STR_TO_DATE(%s, "%m/%d/%Y %H:%M:%S.{%f}"),
...)"""
cursor.execute(sql_stmt, (..., mydate_from_csv, ...))

"milliseconds" really inside curly braces?)

No, because this regexp also matches stuff like "99:99:99.999".
Checking for the number of digits is not enough, because not all

Punctuation characters like the comma are not considered as word

If you want to treat them as "word" characters you need to add them to
the string "wordchars" (a public attribute of the "shlex" instance):
>>> lexer = shlex.shlex("foo.bar, baz")
>>> lexer.wordchar += '.,'
>>> print lexer.get_token()
foo.bar,
>>> print lexer.get_token()
baz
There is also a "debug" attribute (with three different levels: 1, 2, 3;
default value 0 means no debug output):

For the readers who don't bother clicking on the link above: It's a
short video where the OP demonstrates how her/his usage of tail doesn't
work.
no matter call tail directly in python or using the script of tail
all failed
it seems it can not read next line
In your video you use gedit to write some file and "tail -f " to
follow it. But "tail -f" will follow the file descriptor. Usually,
editors like gedit won't save your changes to the original file but
create a new temporary file and rename it later to the original file
name after deleting the original one. Thus tail will follow an already
deleted file.
See also this blog post:
http://tech.shantanugoel.com/2009/12/23/continuous-monitor-tail-fails.html
For your example you will have to use "tail -F " which will follow
the file name.
Alternatively you could write a simple script to simulate a continously
growing file like
import time
for i in range(1000):
with open("test.txt", "a") as f:
f.write(str(i) + '\n')
time.sleep(1)
which should work with "tail -f".

The python interpreter is skipping to the 'math = re.search' and then the

I'm not sure if I understand your problem, but your regex pattern only
matches up to the size. When you look for the referrer, the pattern
expects two quotes but in your string you have "-" (quote, dash, quote).
Thus there is no match (i.e. "match" is None) and the if-statement will
print "not found".

For bitly links you need to use their API: http://dev.bitly.com/links.html#v3_expand There is a python module for interacting with it: https://github.com/bitly/bitly-api-python Bye, Andreas -- https://mail.python.org/mailman/listinfo/python-list
Re: How to add a current string into an already existing list

Trying to add the current filename into the existent 'downloads' column
Somehow i don't think i just use the plus sign into an existing column.
We don't try to add numbers here but add an extra string to an already
existing array of strings(list).
[SNIP]
# update specific visitor's download record
cur.execute('''UPDATE visitors SET downloads = downloads + %s WHERE host
= %s''', (filename, host) )

Well, when do you understand that your MySQL problems have nothing to do
with Python?
Everything inside the triple quotes is MySQL specific, so it's a MySQL
problem whether you can use + to "add an extra string to an already
existing array of strings(list)".
This list is not a MySQL support forum.

Why do you have to do c.module? I'm expecting an output just by creating an
instance of B.
Why do you expect an output? In B.__init__ you are just assigning the
return value from A.log() to the attribute "module" and in A.log() there
is no output either.

Re: Python gp.ListFeatureClasses return only one file

Hi All,
I m using the gp.ListFeatureClasses to make a list of file in my

however when I print the variable in which the List is supposed to be

does any one have an idea
Depending on the version you are using, "ListFeatureClasses()" returns
either a list or an enumeration object:
http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?TopicName=ListFeatureClasses_method
You are just printing the first item. To print all, something like the
following should work (assuming you are using version 9.2):
shpList = gp.ListFeatureClasses("*.shp")
shp = shpList.Next()
while shp:
print shp
shp = shpList.Next()
