Easiest way I know of goes something like this:

for line in myfile:
   newline = '\t'.join(line.split())

Consider:

In [16]: x = 'the quick brown    fox   ate   some   spam and     eggs'

In [17]: x.split()
Out[17]: ['the', 'quick', 'brown', 'fox', 'ate', 'some', 'spam', 'and',
'eggs']

In [18]: '\t'.join(x.split())
Out[18]: 'the\tquick\tbrown\tfox\tate\tsome\tspam\tand\teggs'

In [19]: print '\t'.join(x.split())
the     quick   brown   fox     ate     some    spam    and     eggs
