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

No, two of the binary data files are integers and the third file is a
float.  The data is large and the binary saves time and space.

Do you want to write a TEXT representing the binary values?

for datum in data:
 print ' '.join(map(str,datum))

Everything works in my program except for when it prints out the number is
surrounded by brackets but I need to print the number without the brackets.
Does anyone know an easy way to do this?
#!/usr/bin/env python
import array
fin = open('relative_x.INT32','rb')
fin1=open('relative_y.INT32','rb')
fin2=open('income.INT32','rb')
outfile=open('test.txt','w')

data=[]
data1=[]
data2=[]
while True:
   try:
   myInts=array.array('l')
   myInts.fromfile(fin,1)
   data.append(myInts.tolist())
   myInts1=array.array('l')
   myInts1.fromfile(fin1,1)
   data1.append(myInts1.tolist())
   myInts2=array.array('l')
   myInts2.fromfile(fin2,1)
   data2.append(myInts2.tolist())
   data3=zip(data,data1,data2)
   except EOFError:
   break

   for record in data:
   print record[0],record[1],record[2]
