How to write integers to a file?

[Steven Sartorius]

I'm trying to write a series of whitespace delimited integers to a file.
The 'write' method only accepts strings and using arrays produces binary
data when I open the file with less.  What I want is somehting like
printf for python.  Is there any easy way to do this?  (there must
be...this is python!)

Any help much appreciated...

Thanks,
