There's no need to parse the solution gotten from gambit as a string,
because it returns a list of strategy profiles (which itself is kind of a
list). Also, parsing the output as a string causes errors when the solver
returns a Rational output.
{{{
#!python
sage: import gambit
sage: from sage.game_theory.parser import Parser
sage: g = gambit.Game.new_table([2,2])
sage: solver = gambit.nash.ExternalLCPSolver()
sage: p = Parser(solver.solve(g, rational=True))
sage: s = p.format_LCP(g)
}}}
{{{
309 nice_stuff = []
310 for gambitstrategy in self.raw_string:
--> 311 gambitstrategy =
eval(str(gambitstrategy)[str(gambitstrategy).index("["):
str(gambitstrategy).index("]") + 1])
312 profile =
[tuple(gambitstrategy[:len(gambit_game.players[int(0)].strategies)])]
313 for player in list(gambit_game.players)[1:]:
NameError: name 'Fraction' is not defined
}}}
Also, all output generated by the gambit python interface uses the same
format, so a general name 'format_gambit' fits more than 'format_LCP'.
