Concatanating array by While on Python

Question

I had some question on python,

I am trying to write something, where after each raw-input , I should input into program some data (with array form). Then this data (arrays 2 dimensioanl ) should be added to the other 2 D array Full of zeros. Then when I input the second data (it should be again changed to 2 D array) and must be added to array Which already contain the array with Zeros and array from input). And so , after each input , array should be added already created arrays. Here is the code.

from numpy import *

var=zeros(shape=(1,11)) #making 2D array with zeros

while True: 

    file=raw_input("write data file name or path")

    c=open(file, 'r')
    ArrayStr=loadtxt(c, dtype='S',) #making array

    var=vstack((ArrayStr, var)) # concatantaing array 
print var

So finally I am getting array, which have only 2 arrays concatanatted (arrays with zeros and last inputted data array)

Thanks for attention and help

Code

import numpy

zeros = numpy.zeros(shape=(1,11)) #making 2D array with zeros

var = None

for i in range(1, 3):
    i1 = open("in" + str(i) + ".txt")

    a = numpy.loadtxt(i1, dtype='S')

    if var is None:
        var = numpy.vstack((a, zeros))
    else:
        var = numpy.vstack((var, a, zeros))

print var

Output
