Sounds like homework. Here some suggestions:
- for each file, create a dictionary (see help(dict)
in the python shell for details) and populate it with
the values, so that e.g.
d1['def'] = 'abc def hij'
(help("".split), perhaps help("".strip))
- for each key in the first dictionary, look whether
it exists in the second, if not, write the value (the
line extracted in the first step) out.
(help(dict.iteritems), help(dict.has_key))
(Note that for
if a_dict.has_key("def"): pass
one can also write
if "def" in a_dict: pass
but you won't find this in the simple on-line help,
at least in my version)
