[問題] 取值問題

[zxc1660 (對的人)]

底下是我的簡易程式碼
def main():
    done_jobs = {}
    result_file = open(out_filename,'w',0)
    db = []
    best_mape = 100000000

    for line in jobs:
        for (c,g,p) in line:
            while not done_jobs.has_key((c,g,p)):
                (worker,c1,g1,p1,mape) = result_queue.get()
                done_jobs[(c1,g1,p1)] = mape
                result_file.write('%s %s %s %s\n' %(c1,g1,p1,mape))
                result_file.flush()
                print "[%s] %s %s %s %s" % (worker,c1,g1,p1,mape),
                if mape < best_mape:
                    best_mape = mape
                    best_c = 2.0**c1
                    best_g = 2.0**g1
                    best_p = 2.0**p1
                print " (best c=%s, g=%s, p=%s, MAPE=%s)" % \
                    (best_c, best_g, best_p, best_mape)

main()

如果我要取main中的mape值，我該如何取阿?試好久都試不出來 @@""
先謝謝高手的解答

推 Leland:考不考慮把 mape 變成 global？或是寫成 class？
