Hi,
I have the following simple code:
r = {}
r[1] = [0.00]
r_new = {}
print r[1][0]
r_new[1] = r[1]
r_new[1][0] = r[1][0] + 0.02
print r[1][0]
It outputs:
0.0
0.02
it is something strange to me since in the first and second case I
output the same variable (r[1][0]) and it the two cases it

I don't think so. There is no sqlite module in
Hi,
I have the following small problem. I run Python interactively. In the
beginning of the run I import many functions from many modules. Than I
execute some commands and notice that one of the imported functions
contains a mistake. I open another terminal in which I open the file

I try to build and install pysqlite? After I type python setup.py
build I get a lot of error messages? The first error is src/

I assume that the absence of the sqlite3.h is the origin of the
problem.

Hi,
I would like to import a function from a file which is located not in
the same directory as the main program (from which the function needed
to be imported).
Could anybody pleas tell me how to do that?
Thank you in advance.

Hi,
I would like to declare a global variable, which is seen to a
particular function. If I do as the following it works:
x = 1
def test():
global x
print x
return 1
However, it does not helps since my function is in a separate file. In
other words I have a main program which has the
Hi,
Does Python have a free source community for the numerical problems
coding? I mean, are there some web-sites where I could find a free
code for such problems like calculation of eigenvectors and
eigenvalues of matrices?
Thank you!

Hi,
I am totaly newbie in the Python's web programming. So, I dont even
know the basic conceptions (but I have ideas about php-web-
programming). Does it work in a similar way? First, I have to install
a Python-server?
On the server where I have my web site (it runs under Linux) if I type
python
1. On my server (in my directory) I found cgi-bin subdirectory.
2. In the cgi-bin I have created a file test.py.
3. In that file I put:
#!/usr/bin/python2.4 python
print Hello, World!
(I have checked, I have /usr/bin/python2.4 directory.)
4. I give the following permissions to the test.py:
Hi,
I have a class called vector. And I would like to define a function
dot which would return a dot product of any two vectors. I want
to call this function as follow: dot(x,y).
Well, I can define a functions dot outside the class and it works
exactly as I want. However, the problem is that

Hi,
I start to learn the object oriented programing in Python. As far as I
understood, every class has a set of corresponding methods and
variables. For me it is easy to understand a method as a one-argument
function associated with a class. For example, if I call x.calc and
y.calc and if x and y
Hi,
I just started to learn Python. I understood how one can create a
class and define a method related with that class. According to my
understanding every call of a methods is related with a specific
object. For example, we have a method length, than we call this
method as the following
Hi,
I found one example which defines the addition of two vectors as a
method of a class. It looks like that:
class Vector:

for j in range(len(self.data)):
data.append(self.data[j] + other.data[j])
return Vector(data)

I would like to know what are advantages of Python in comparison with C
++? In which cases and why Python can be a better tool than C++?
Thank you!
