Hi, I have problems using characters from the Swedish language. I tried
the
following in IDLE under MacOS X leopard (running Python 2.5.1) :
S='?'
Displaying error message: "unsupported characters in input".
To use non-ascii characters in Python code you have to declare the
encoding of the source file with a comment such as
# coding=UTF-8
See http://python.org/dev/peps/pep-0263/

Thanks for taking you time with this. Yes, that works. I know that you can
declare the encoding for a script in that way but there is still a problem
when I use the shell as input device. There are options for encoding in the
menu for IDLE but changing them doesn't help at all. I've tried two versions
of IDLE but both seem to be a bit buggy (scrolling doesn?t work, etc). If
there are any Mac users who read this, which editor would you recommend for
Mac?

I dont think that this program uses the gaussian function, am I in the right
wavelength?
from __future__ import division
import math
a=raw_input("What is the value of xmin?")
b=raw_input("What is the value of dx?")
c=raw_input("What is the value of nx?")
xmin=float(a)
dx=float(b)
nx=int(c)
n=int(c)
l=[]
for x in range(0.00,n):
print xmin+x*dx
def line(n):
s=''
i=raw_input("Please choose a scale for your plot")
n=int(i)
for j in range(0.00,n):
s= s+ "***" + "\n"
print s
return s
def gauss(x):
gaussa=math.pi(2)
gaussb=math.sqrt(gaussa)
gaussc=1/gaussb
gaussd=math.exp(-0.5*-2.00**2)
gausse= gaussc*gaussd
print gausse

Hey. Is there anyone who can give me some help?
Below is the question I was set.
This sounds like a homework assignment. We don't write programs for
assignments. We offer help after you give it your best effort.
I am having trouble with the gaussian function and don't really know
where
to start.
It sounds like you are having trouble with programming, not with the
gaussian function. Did you run the following code? Did it give you any
useful results? (I expect it to raise an exception.) At least run it and
see what happens. How does it contribute to the overall result?
s=''
for n in range (0,100):
s=s+ '*'
print s
Can you at least outline the program or algorithm as a starting place.
"Write a program which asks the user for values
of xmin, dx and nx. The program should then
output a plot of the gaussian function
at the following series of values of x:
xmin, xmin+dx, xmin+2*dx, xmin+3*dx, : : :,
xmin+(nx-1)*dx. e.g. the following output
should result if xmin = 2:5, dx = 0:5 and
nx = 11.
-2.50 *
-2.00 ***
-1.50 ******
-1.00 ************
-0.50 ******************
0.00 ********************
0.50 ******************
1.00 ************
1.50 ******
2.00 ***
2.50 *
The program should contain and make full use
of the following functions:
gauss(x) - Returns the value of the Gaussian
function
line(n) - Prints a line of n asterisks followed
by a newline character.
You will need to choose a scale for your plot;
in the example shown the number of asterisks
is 50 * gauss(x).
Should I start with a program like this?
s=''
for n in range (0,100):
s=s+ '*'
print s
Thanks for any help received. :confused:

hello, guys:
Sorry to ask a question not related to python, but to the mail list.
That is i use thundbird to read the list, just find when a post with
many threads is clustered and unfriendly to me. My question is there a
way to read messages sorted by thread ( just like in web version
http://mail.python.org/pipermail/ ) but in thunderbird or other mail
applications, or other way better ?
thks
