[Tutor] can't install
ive struggled all day to install pip on ubuntu 12.04 for python 3.3 . The only pip in the apt-get cache is for python 2. i tried to download pip from source but setuptools is missing when it tries to import it. This made me download setuptools with apt-get but the version there is only for python 3.2 I've also download the distribute_setup.py file to get pip through easy_install but it returns errors when it uses urllib.request. Something to do with https, although the same distribute_setup.py worked perfectly when i used it on windows for 3.1 and 3.3. This all started because i wanted to use virtualenv. After installing it i couldn't use it cos it needed zlib which i didn't have. apt-get only has zlib for python 2.7. I'm now at my wit's end. Life was great using windows. Everyone told me try ubuntu, now life is so stressful, even on christmas eve:( Any ideas on how to solve this issue would be appreciated:(___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

[Tutor] cant autoincrement
I'm doing a test database with sqlite and have run into some problems. in my 1st table i have an id field: id INTERGER Primary Key the database has a few more fields, but when i insert into it, i leave the id field empty as it should be done automatically, but sql complains with an error that i have left the field blank. If i manually put the ids in, everything works, but from my understanding this should be done automatically, aswell as it auto incrementing? i have two tables table1 (id, field 2, field 3, field 4) table2 (id, field 2, field 3, FOREIGN KEY (field 3) REFERENCES table1(id)) i initially had a problem as foreign keys is not enabled by default but as my auto increment isnt working, can i just ask what does sql insert into field 3 of table2 as its a foreign key. Does it automatically insert the correspond id of table1, or is it up to me to manually insert the correct data into table2 that match with the keys on table1? I ask only because i havent had a chance to try it myself as i still have a problem with the keys, and strangely enough if i put random text into the foreign key of table 2 that didnt reference any ids on table1, sqlite still inserts them with no errors when they clearly ignore the instructions given.___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] cant autoincrement
what does your insert statement look like? According to the documentation (http://www.sqlite.org/faq.html#q1): whenever you insert a NULL into that column of the table, the NULL is automatically converted into (1 + the highest value). The insert statement should look like: INSERT INTO t1 VALUES(NULL,123); i included the null, my results are: cursor.execute(INSERT into person VALUES(NULL, arg1, arg2)) my result is: (None, value1, value2) #the key being None :( also thanks for the link___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

The dot (.) command is used to source a file, It executes Unix like commands
in bin/activate. Not relevant when you're on windows. Is there a .bat or

i looked at the activate file which doesnt have an extension. the code is not
in python so im trying to figure out code i have no clue where its from. that
line where the error is contains the javascript like braces after functions {}
maybe thats it but it seems this tutorial doesnt want me to study it:(

there:

You can use bytes() function:

Re: [Tutor] mysqlite
I finished the tutorial and must say i am very happy. Ill probably go over it again while writing some test dbs.

You need to open a CMD shell window and cd to your SQL database folder (E:\PROJECTS\SQL in the example above) and then run sqlite3. sqlite3 employee.db my main questions are it possible to use the command line without cursor() and connect() in python 3 No only from the sqlite command line. I can only find an sqlite3 folder in my Python installation folder. Python\Lib\sqlite3 the command line command doesnt work from inside this folder, but i am guessing this isnt where im supposed to do it from. Is there a sqlite program i am supposed to install that is separate from the one that came with Python?

[Tutor] mysqlite
im working through alan's sql tutorial. i have a few questions from there but
1st i wanted to try out an example in Core python's sql example.
import sqlite3
cxn = sqlite3.connect('sqlite_test/test')
cur = cxn.cursor()
after this i created a table called users and inserted some data. then i did:
cur.execute('SELECT * from users')
for user in cur.fetchall():
print(user)
i got the results of all data i gave the table. then did
cur.close()
cxn.commit()
cxn.close()
i then closed this interactive IDLE session. i reopened another session and
simply did
import sqlite3
cxn = sqlite3.connect('sqlite_test/test')
cur = cxn.cursor()
for user in cur.fetchall():
print(user)
but this time no data was printed back to me, even though the database file
'test' already existed from the previous session. Why did this happen, cant i
just connect and my data is still intact? or do i have to always re enter data
from the previously saved session?
My questions about http://www.alan-g.me.uk/tutor/tutdbms.htm is to open a
database it uses the command line directly and doesnt creat cursor() or
connect() objects e.g.
E:\PROJECTS\SQL sqlite3 employee.db
sqlite create table Employee
... (EmpID,Name,HireDate,Grade,ManagerID);
sqlite insert into Employee (EmpID, Name, HireDate, Grade, ManagerID)
... values ('1020304','John Brown','20030623','Foreman','1020311');
i tried this in my command line but got :
python.exe: can't open file 'sqlite': [Errno 2] No
such file or directory
i tried creating the a folder called test and doing: test employee.db
but no test.db was created.
my main questions are it possible to use the command line without cursor() and
connect() in python 3 or is it only for python 2. is it better from the command
line or in a .py file. And also my previous question i had about having to re
enter previously stored data

Re: [Tutor] mysqlite

guys i still cant use the command line. but i guess i dont really mind as i
can just make a .py file...
i am having a lot of fun reading through alan's tutorial, everything is
becoming very clear but can someone please explain this to me.
update Employee
set ManagerID = (Select EmpID
from Employee
where Name = 'John Brown')
where Name = 'Fred Smith' OR
Name = 'Anne Jones';
this is saying set the managerID of 'Fred Smith' or 'Jane Brown' to the ID
returned in the nested select statement?
and this:
drop table author;
create table author (
ID Integer PRIMARY KEY,
Name String NOT NULL
);
drop table book;
create table book (
ID Integer PRIMARY KEY,
Title String NOT NULL
);
drop table book_author;
create table book_author (
bookID Integer NOT NULL,
authorID Integer NOT NULL
);
sqlite SELECT title from book, book_author ... where book_author.bookID =
book.ID ... and book_author.authorID = (select ID from author ...
where name = Jane Austin);
maybe its simple but because its more complex im finding it hard to read. we
want a title from book,
which is the field that will be returned, but why is book_author also in the
select statement when it isnt
being returned? or are we actually returning every single field from book
author?
so if the author.bookID is equal to book.ID, also check that this ID from
author matches the authorID from
book_author.authorID ? after comprehending this im lost in my thoughts. can
someone tell me how these are
linked. so the whole output is really dependent on the answer from the 2nd
condition after the and?:
... and book_author.authorID = (select ID from author
where name = Jane Austin);

Im on Windows, and my main worry is confusing my PC and making it get the versions mixed up. i also want to leave room to install version 2 if i ever need to but ill cross that bridge when i get there. For now i want to know if i have to delete version 3.0 before installing 3.3? Also i want to learn web development and saw only a few modules support Python 3. As i don't know anything about this subject i just wanted to ask which is a better bet, Bottle or Cherrypy? I am not creating/managing any websites this is just to learn.

Python 3.3 will definitely install independently of 3.0 on Windows. It's only the minor versions that happen in place, like going from 3.3 to 3.3.1 If you're running your scripts explicitly, by something like: python myscript.py then you should be able to say python3.3 myscript.py or python3.0 myscript.py thanks it installed independently like you said. and those python3.3 or python3.0 in the command line seems to do the trick!___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] some web and python version questions
I don't know how that's working. There are no executables or batch files with those names in the default installations. It's always python.exe. Plus the default install options don't muck with the PATH environment variable. Did you rename (or NTFS symlink) the executables and add the install directories to your PATH? 3.3 installs py.exe to the Windows directory, which you can use like this: py -3.3 myscript.py py -3.0 myscript.py Or add a shebang to the first line of the script such as #!/usr/bin/env python3.0 Then you can simply run myscipt.py. The 3.3 installer associates the extension with py.exe, which parses the shebang line. -- no sorry i made a mistake it didnt work. i cd into the particular python version directory that i named python3.0 and python3.3. sorry that was my mistake. Once i was in the correct directory i used the command: python filename.py in cmd and the correct version was opened. Since installing 3.3 my .py files have lost their python icon, like when there is no default program to open it, looks like this: http://www.google.co.uk/imgres?imgurl=http://filext.com/images/icon_unknownassociation.gifimgrefurl=http://filext.com/faq/remove_filext_get_cknow.phph=48w=39sz=2tbnid=ARzowXfVVRzKFM:tbnh=48tbnw=39zoom=1usg=__aeaxTXEytmXEPgmJ-92PpGRrYho=docid=YuYbltBMCbahiMsa=Xei=21s1UbLjE8i0PLXqgXgved=0CFMQ9QEwAwdur=2179 im not sure what to do because on double click they still open and work fine, so the right program is still opening them.

No idea what you mean by work fine. You mean that it runs 3.0 for some scripts when you right click on the script, and 3.3 on other scripts when you right click on them? In that case, you must have the py.exe associated with the .py directory, and you must have shebang lines in your scripts. no if i double click the .py file, Python 3.3 opens all of my python 3 files. A lot of 3.0 files won't run but that's okay. Now on my command line if i enter the correct version's directory, and use: python myfile.py then the correct version's .exe opens the file.

Installing 3.3 associated .py files with %windir%\py.exe, but it seems the icon cache wasn't refreshed. You can trigger a refresh by setting any default in the Default Programs control panel applet.

Like everything in my tutorial the intention is to get you to the point where you can do the basics yourself but also read and understand the in depth tutorials when you need to go there. i read through some of your tutorial last night and its definately what i need. so i will complete it.. thanks___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] confusing installation
Welcome to the world of software development. GUIs like Windows are great for doing simple things but they can't compete with command line tools for doing powerful things quickly. So pretty much every programmer has to get used to using the command line sooner or later. If you are not used to using the Windowsc CMD program there are several short tutorials available to help you get started. so CMD has features like linux when you can download/install/build files from the command line? i didnt think this was possible easy install is a toolset for making the installation of Python modules easy. Again there are tutorials/manual pages available and the first time you use it you may want to read one of those. on a google search for easy install, easy install python was auto completed. Is this what im after or is it easy install windows? It sounds to me like finding a new tutorial that takes a slower pace might be your best option here. Do you know what you are trying to learn specifically? Or is it just the next topic in the tutorial? Do you have a specific need to use SQL Alchemy? If not maybe you can just jump over a chapter tor two... i want to learn about how to use databases and this specific chapter is meant to introduce its readers to options available (not just SQLAlchemy). It's already at a beginner's level so i might run into the same problems else where. i will look for some easy install tutorials___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] confusing installation
This should be relevant: http://www.voidspace.org.uk/python/articles/command_line.shtml in searching for command line tutorials i also came across Powershell and noticed commands that work in one don't work in the other. Would you recommend Powershell over CMD?___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] confusing installation
Since you use python 3 you will need to download the file: distribute_setup.py. To do so you will need a web browser or the command line tool curl. I use Firefox and when I click on the url you give below it immediately offers to download the required file. thanks i tried it on firefox and it did the trick He is showing you what to expect. Where ever you see a line starting with C:\ that is what he typed into the command line session, and the lines that follow is the program you are installing informing you what it is doing. (Until you get to the next C:\ or the end) thanks for this explanation, i will try and read that section a bit more carefully and do what he is typing ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

(Until you get to the next C:\ or the end) i managed to install that file but in the book it shows the file going into http://www.alchemy.org/ and installing it into site packages, my install unfortunately didnt do this very last step that involved adding sqlalchemy to easy-install.pth. not sure how to fix it thanks to every that has helped___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] confusing installation
problems else where. i will look for some easy install tutorials If you just want to know about SQL databases you could try my tutorial topic (only in the V2 version at the moment but it's nearly identical on V3) It uses SQLite which is part of standard Python, although you can also download a Windows installer for standalone use. If nothing else it will give you a quick intro to the topic and doesn't cost anything but time... It sounds like your book is covering a wider range of options than SQL but you might still find mine useful. i didnt see this Alan. my interests is only SQL but the book indicates things like ORMs are very important?.. but it doesnt cover SQL indepth, just simple examples of the same script in sqlite mysql postgresql and gadfly i think. Im definately after an indepth SQL tutorial. I'll have a look at yours now.___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
[Tutor] confusing installation
Hi all. Im working through a database tutorial in a book called Core Python Applications. On page 290 it asks of me to install something though its not clear what it is. I think it has to do with SQLAlchemy. It says if you use Python 3 you'll need to get distribute first. You'll need a web browser (or the curl if you have it). Mind you i havent a clue what it is on about.. then it goes on: And to download the installation file (available at http://python-distribute.org/distribute_setup.py), and then get SQLAlchemy with easy install. Here is what this entire process might look like on a Windows-based PC... then it proceeds to write a whole bunch of god know what. It looks similar to when you install something on linux.. Im a windows only user btw. That link i went there to download the file but if you look at that site i dont know what on earth im supposed to do to install/retrieve that file. I do not know what easy install is.What do they mean i need a web browser? doesnt every computer have a web-browser?? what is curl?? I can not proceed with this tutorial if i recieve no help... Please can anyone assist me on what i have to do to use the tools they are presenting. i use Python 3 and Windows___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
