Make an assignment to a str object:

>>> pri={2000:{0.233:0,0.444:0}}
>>> s = "%s %s" % (pri.keys()[0], " ".join(map(str, sorted(pri[pri.keys()[0]]))))
>>> s
'2000 0.233 0.444'
>>>

In case pri has more than one key:

>>> pri={2000:{0.233:0,0.444:0}, 2001:{0.234:0,0.445:0}}
>>> s = "\n".join([" ".join(map(str, [subkey]+sorted(pri[subkey].keys()))) for subkey in pri.keys()])
>>> print s
2000 0.233 0.444
2001 0.234 0.445
>>>
