Thanks again, i thought so, and tried that, too.

.. but it still won't run.
I get an Unbound Local error at the first imported function..

Here is the error, and the relevant code, if anyone can help...

here is the part that chokes:


--------:file:profile_soko.py:-----------

import sokoban
import sys, time
import profile

filename = sys.argv[1]  <= not the problem, arg is passing ok..

def solve_problem():
    print 'you chose: ', filename     <= works during profile run...

    solv = sokoban.solver_class(filename)   <= chokes here, caused by
imported sokoban.py

    start_time = time.time()
    solution = solv.find_solution()
    elapsed_time = time.time()-start_time

    print filename
    print elapsed_time, 'seconds'
    print solution



print 'direct:'
solve_problem()

import __main__
__main__.solve_problem = solve_problem

print 'profiled:'
profile.run('solve_problem()')


--------------::file sokoban.py::-------------------------------
...

def load_soko(file_name):

    file = open(file_name,'r')    <== line 358: Unbound Local error:
'file_name'
    lines = file.readlines()                ( what's up with that???)
    file.close()

    ... more stuff..


class solver_class:
    def __init__(self,filename):

        self.board, blocks, soko  = load_soko(filename)

        ...more stuff...


It also still works if I call exec('solve_problem()'),
but not if call profile.run('solve_problem()').
