Joining data from three different files to be written into three Columns

[Dawn Abbott]

I have three files of binary data.  I want to write the three binary data
files to one file.  I want the old files to each have their own column in
the new file.  This is what I have,

f=open('relative_x.INT32','rb')
a=array('l')
a.fromfile(f,10)
g=open('relative_y.INT32','rb')
b=array('l')
b.fromfile(g,10)
data=zip(a,b)
for datum in data:
...    print ' '.join(datum)
...


the error I get is expected string, found int
I figure that the joint is for strings only does anyone know of a way were I
could join the data that would be for ints.
Thanks
Dawn
