CONTEST - What is the (best) solution?

[python at hope.cz]

In a file there can be several dictionaries like this
{Key11: Value11
Key12: Value12
Key13: Value13,
...
...
Key1n:Value1n}
{Key21: Value21
Key22: Value22
Key23: Value23,
...
...
Key2n:Value2n}
{Key31: Value31
Key32: Value32
Key33: Value33,
...
...
Key3n:Value3n}
....
....
....
{Keyn1: Valuen1
Keyn2: Valuen2
Keyn3: Value3,
...
...
Keynn:Valuenn}

Each pair in a dictionary is separated by CRLF and in each dictionary
numbers of pairs can be different.
I need to read only the the first and the last dictionaries.What is a
best solution?
Thanks
