Many thanks for pointing out File.softspace attribute.  However, I get mixed
results when using it.  I am sure there is some logic to it somewhere.  It
does not appear to control the end of line.  The online doc says that it
controls putting a space -before- another value.  The File.softspace.__doc__
string appears to need review also.  I think I am ready to use File.write()
and move on.

C:\src\projects\test1>type eoltest.py
#!/usr/bin/env python
import sys
print 'here', 'and'
sys.stdout.softspace = False
print 'here', 'and'
sys.stdout.softspace = True
print 'here', 'and'
sys.stdout.softspace = False
print 'there',

int(x[, base]) -> integer

Convert a string or number to an integer, if possible.  A floating point
argument will be truncated towards zero (this does not include a string
representation of a floating point number!)  When converting a string, use
the optional base.  It is an error to supply a base when converting a
non-string. If the argument is outside the integer range a long object
will be returned instead.
