[Tutor] Gaussian function

[optimum]

SOrry, just started python programming. I have so much to learn still.
My output was 
What is the value of xmin?-2.5
What is the value of dx?0.5
What is the value of nx?11
-2.5
-2.0
-1.5
-1.0
-0.5
0.0
0.5
1.0
1.5
2.0
2.5
Please choose a scale for your plot50

I think I called the functions now...but I don't get the desired output, is
it my gaussian function which is wrong?
We had a lecture on "def" function, but wasn't really told how to do this
program. 

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
    return gausse
    print gausse

    
    
line(gauss)
