including array in structured module

[coolindienc]

I got the program below and now I want to put this in a structured module. Andy suggestions?

from numarray import *
 
n=input("Enter number of elements: ")
x=zeros(n,Int)
for i in range(0,n):
    print "Enter the value for x subscript ",i
    x[i]=input()
 
    print x
 
print "The final output is a List of n elements where n is:",n
raw_input("Press enter to exit.")

from numpy import *
 
def InitArray(n):    # this is a comment. below is a docstring (self documenting code is a very good habit to get into)
    """Given the number of elements (n), return a 1d array"""
    return zeros(n, int16)
 
def GetInput():
    return input("Enter number of elements: ")
 
def FillArray(xArray, nElems):
    for i in range(nElems):
        print "Enter the value for x subscript ",i
        xArray[i]=input()
 
        print xArray
 
if __name__ == "__main__":
    n = GetInput()
    myArray = InitArray(n)
    FillArray(myArray, n)
    print "The final output is an Array of %d elements is:" %n
    print myArray
    for x in myArray:
        print x
    raw_input("Press enter to exit.")
 

I don't have numarray module. numpy is more up to date and complete. You can change it back to numarray, but this is tested.

This shows how mutable objects get passed by reference and can be change in a fuction without a need for returning the reference. This is advanced stuff to use, but a basic concept that needs to be understood early in your education.
