reading from a gzip file

[Nader]

Hello,

I have a gzip file and I try to read from this file withe the next
statements:

 gunziped_file = gzip.GzipFile('gzip-file')
 input_file = open(gunziped_file,'r')

But I get the nezt error message:

Traceback (most recent call last):
  File "read_sfloc_files.py", line 131, in ?
input_file = open(gunziped_file,'r')
TypeError: coercing to Unicode: need string or buffer, instance found

I think that I do some mistake. Would some body tell me what is my
mistake?

I would accept your suggestion in raltion of checking a list whether
it is empty or not with "if" statement. It is more expressive and
clear. But In this case I would learn more about the "try  except"
exception.

Checking list by using of exception

[Nader]

Hello,

I read some files name from a directory and then I put these name in a
list. I will check whether it is empty or not, and I would do it with
an exception. With if statement it is very simple:

If list_of_files != ""  :# this can be if list_of_files !=
[]:
  get the files
elas:
   there is no file

But with exception, I can write something as:

try:
   list_of_files != []
   get the files
except ValueError:
Print " there is no file"

What can the first statement be inside 'try' if I don't want to use if
statement?
Maybe my understandig of exception is enough to got it.

Would somebody explain me about this?

Regards,
Nader


try and except   in a dircMaybe this quetion will be simple enough for
you.

Thank you! It is the anwser which I was looking for. [(k,v) for k,v
in  d.items() if v is pattern].
But I don't understand what tou mean of "reverse look-up a lot"! I
have to read some informations inclusive (latitudes and longitudes)
form a file and after some processing to save part of this information
to other file.
Why do I make a new dictionary?

Thank for your type about the syntax error. This an example example,
the keys of my dictionary are tuples:
d = {(37.75, 42.22): 1 , (37.51, 40.02): 3 (45.55, 24.27): 4 (47.08,
30.99) : 1}

But what I will is to get all keys which has the same valus. And not
the keys that have value more than 1!

Is it niet possible with one or two statement, maybe with list
comprehension. For exmple:

l = [(k,v) for k in d.keys() for v in d.values() | en here we need
some extra logic (v = 1)]

I don;t konw how we can define a logic statement in a list
comprehension.
It will be very compact, if it would possible.

get keys with the same values

[Nader]

Hello,

I have a dictionary and will get all keys which have the same values.

d = {('a' : 1), ('b' : 3), ('c' : 2),('d' : 3),('e' : 1),('f' : 4)}

I will something as :

d.keys(where their values are the same)

With this statement I can get two lists for this example:
l1= ['a','e']
l2=['b','d']

Would somebody tell me how I can do it?

If I do the next :

 t1 = [(round(float(x),1), round(float(y),2)) for x, y in t]

I get the long float as :

[(35.797, -0.23999), (33.297,
-2.71), (33.601,-2.4199)]

But I would have a float with 2 decimal numbers.

str to float (rounded)

[Nader]

Hello,

I have a list of tuple with strin elements. These elements are number,
but they are save as string. Now I will change the string to number
which will be rounded. An example will make it more clear.

t = [('35.757', '-0.239'), ('33.332', '-2.707'), ('33.640', '-2.423')]

And I will have the next list:

t = [(35.76, -2.24), (33.33, -2.71), (33.64, -2.42)]

The elements of tuple are not more as string.

Would somebody tell me how I can do that?

lists to save in a tuple

[Nader]

Hello,

I have two lists and would save them in a tuple.

a = [1,2,3]
b = ['a','b','c']

with the next statement I can do that:

t = [(x,y), for x in a for y in b]

This gives the next list:

[(1,'a'),(1,'b'),(1,'c'), (2,'a'),(2,'b'),(2,'c'), (3,'a'),(3,'b'),
(3,'c')]

But I want the next list:

[(1,'a'),(2,'b'),(3,'c')]

Would somebody tell me how I can solve this problem?

Hello Paul,

I have returnd to the begining and have installed everthing again.
Fortunately now I have the 'pysqlite2' module, because the test.test()
workd after importing of 'pysqlite2'

 >>> from pysqlite2 import test
>>> test.test

>>> test.test()
.
--
Ran 173 tests in 0.585s

OK
>>>

And the result of running of 'ldd' is :
[EMAIL PROTECTED]:~> ldd lib/python2.4/site-packages/pysqlite2/_sqlite.so
linux-gate.so.1 =>  (0xe000)
libsqlite3.so.0 => /usr/people/emami/lib/libsqlite3.so.0
(0x4001)
libpthread.so.0 => /lib/tls/libpthread.so.0 (0x40096000)
libc.so.6 => /lib/tls/libc.so.6 (0x400a7000)

Now I can ggo on with TurboGears! I have at home a Laptop and I have
installed the 'gentoo' on it, and have no problem. But I would like to
experiment with TurboGears at my work and It was a problem that I had
no 'root' password.
However I appreciate well your help in this case. I you like Indian or

Hello

I have expanded the LD_LIBRARY_PATH to my home lib (export
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/people/emami/lib).
I have built and installed the 'pysqlite-2.3.3' with the next
'setup.cfg' :

[build_ext]
define=
include_dirs=/usr/people/emami/include
library_dirs=/usr/people/emami/lib
#libraries=/usr/people/emami/lib/libsqlite3.so  (this line as a
comment)

The resutl of this process was:

running install_lib
copying build/lib.linux-i686-2.4/pysqlite2/_sqlite.so -> /usr/people/
emami/lib/python2.4/site-packages/pysqlite2
running install_data

This message had given after installing. I have controll the '/usr/
people/emami/lib/python2.4/site-packages/pysqlite2' whether the
'_sqlite.so' has copied there. Yes it has. Okay!
I go to python and I give the next command:
>>> from pysqlite import test

and Unfortunately I get the next error message:

Traceback (most recent call last):
  File "", line 1, in ?
  File "/usr/people/emami/lib/python2.4/site-packages/pysqlite2/test/
__init__.py", line 25, in ?

transactions,\
  File "/usr/people/emami/lib/python2.4/site-packages/pysqlite2/test/

from pysqlite2._sqlite import *

Do you know what option I have to give to if I want to use the

%easy_install pysqlite (with some optione with which it cab find the

Hello,

I am back with another problem. I suppose that I can tell it!
I have installed both, 'sqlite' and 'pysqlite' without any problem. But 
If I try to test whether the 'pysqlite' interface works, I get the next 
error message:

 >>>from pysqlite2 import dbapi2 as sqlite
Traceback (most recent call last):
   File "", line 1, in ?
   File 
"/usr/people/emami/lib/python2.4/site-packages/pysqlite2/dbapi2.py", 
line 27, in ?
 from pysqlite2._sqlite import *
ImportError: 
/usr/people/emami/lib/python2.4/site-packages/pysqlite2/_sqlite.so: 
undefined symbol: sqlite3_set_authorizer

I don't understand it. Could you tell me how I can solve this last 
point? I hope so!

With regards,

Nader

I have first installed "sqlite" and then I have configure the 
"setup.cfg" file of "pysqlite" package. I had to do two things in
'pysqlite' directory:
1- python setup.py build
2- python setup.py install

It has done without any error. I suppose that the installation is well 
done, but I haven't yet test whether I can import the 'pysqlite' module 
in python. But how you mean about "PYTHONPATH"? If I do "echo 
$PYTHONPAT" i get an empty string. That meant that I don't have any 
"PYTHONPATH". How can I assign a correct "path" to this variable?

Thank for your reaction. I don't know also how the interaction sith
'easy_install' is. I think that I have to install 'pysqlite' from
source code also, because i can change ther the 'setup.cfg' file and I
can give there where the 'libsqlie3' is.

compile python with sqlite3

[Nader Emami]

L.S.,

I have to compile (install) locally Python 2.5, because I don't have 
'root' permission. Besides I would use 'sqlite3' as a database for 
TurboGears/Django. I have installed 'sqlite3' somewhere on my Linux 
(/path/to/sqlite'). What do I have to do if I want to compile 'Python' 
with 'sqlite3'? I would appreciate if somebody tells me to solve this 
problem.

L.S.,

I have read your replay about web development with python. I would agree
with you that web design is depends on specific requirements. I would

but I do not which of them I can choose for my application.
I will appreciate you if you would give me some advice in this case.

I have a long command in Unix and I have to use os.system(cmd)

cmd = '%s/mos user wmarch, cd /fa/wm/%s/%s, mkdir %s, put %s, chmod 644 
%s' % (mosbin, jaar, filetype, filetype)
status = os.system(cmd)

This is not very clear, and I have to break this long line in two 
segment by means of the next character '\' :
cmd = '%s/mos user wmarch, cd /fa/wm/%s/%s, mkdir %s, put %s, \
   chmod 644 %s' % (mosbin, jaar, filetype, filetype)

But in this case I get a syntax error! I don't know how I can solve this
