I have to say this and other answers in this thread seem not that friendly to
me.
The OP said it's a newbie question, we should be more welcoming to newcomers.

Yeah! And I'm surprised no one came up with:

>>> sum(takewhile((100).__gt__, filter((2).__rmod__, m

Hi
I am a newbie to python and am trying to write a program that does a
sum of squares of numbers whose squares are odd.
For example, for x from 1 to 100, it generates 165 as an output (sum
of 1,9,25,49,81)

No, python doesn't pass variable either by value or by reference. The

These statements are both wrong. Function argument objects or objects
derived therefrom are bound to function parameter names

One of the many lovely things about programming in the
Python style is that very few things need to be global.

Python does not use "call by value" or "call by reference" semantics.
Instead, python's model is "call by object". See this writeup for
some

When you call c3.createJoe(c1.fred), you are passing a copy of the
value stored in c1.fred to your function. Python passes function
parameters by value. The function will not destructively modify its
arguments; you must expliticly state your intention to modify an
object:

In Python, there are names which are bound to objects. Doing "foo = bar"
and then "foo = s
Why can I not the change the value of a variable in another class,
when I have passed it via a parameter list.
I am sure I am being stupid, but I thought passed objects were Read/

eg
#!/usr/bin/python
class one(): #my Global Var
In short input runs an eval on the text before it passes it! So input like
ord('a') will work fine because it will run that code!
