Python Source
I am not sure whether this group is the best place to post my thought. I will ask neverthless: Is it possible to hack through the code written by Guido van Rossum that makes the python interpreter. If yes please let me know how to begin. If its not then pardon me. -- http://mail.python.org/mailman/listinfo/python-list
Where is __builtin__
Most of the other modules have an accompanying python source file. But that is not the case with __builtin__. What might be the reason? Isn't __builtin__ written in python? -- http://mail.python.org/mailman/listinfo/python-list

It is not clear whether you want to accept a list variable or an arbitrary number of values as parameter to the function. So I will explain each case. def ex(name,*items): Here name, description and items can all accept lists as arguments. Additionally items can accept arbitrary number of arguments even of different types. Ex: ex([10,12],12,13.3,'Python') > > Question 2: How do I signify to accept each item as one list?

No need u can pass a list directly into the call. -- http://mail.python.org/mailman/listinfo/python-list
I want to work on Python
Hi there, these days I am desperately searching everywhere on the Internet for part time python jobs. The reason is I want to get actively involved with python programming and get some practical exposure. Please help me in whatever way you can. -- http://mail.python.org/mailman/listinfo/python-list

The thing is that the parameter 'bar' is actually a dictionary object so the right way of calling shuf is then x,foo,bar = shuf(1,2,3,4,5,a=6,b=7,c=8) -- http://mail.python.org/mailman/listinfo/python-list

Probably the server is not executing your CGI script. If it is the
Apache web server that you are using then just ensure the following
settings in your /etc/httpd/conf/httpd.conf file is exactly like
following:
AllowOverride None
Options ExecCGI
Order allow,deny
Allow from all

Oh yes...Your script is supposed to replace apache. I tried with your
script on my pc and its working just fine. However the problem still is
that the server is taking your file to be a plain file rather than a
CGI script. Looking at CGIHTTPServer.is_cgi method might prove helpful.

Help me understand this
Hi,
Pls tell me whats going on in the code snippet below:
>>> n = 10
>>> statstr = "N = ",n
>>> type(statstr) #case1
>>> print statstr
('N = ', 10)
>>> print "N = ",n #case 2
N = 10
In the first case the result is printed as a tuple and in the second
it appears as an ordinary string.
