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 ha

I have the following small problem. I run Python interactively. In the

execute some commands and notice that one of the imported functions
contains a mistake. I open another terminal in which I open the file

Hi,
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/
connection.h:33:21: error: sqlite3.h: No such file or directory". So,
I assume that the absence of the "sqlite3.h" is the origin of the
problem.
I found on th
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,
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 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 follo

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
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"

Hi,
I found one example which defines the addition of two vectors as a
method of a class. It looks like that:
class Vector:
def __add__(self, other):
data = []
for j in range(len(self.data)):
data.append(self.data[j] + other.data[j])
return Vector(data)

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 "x.len
