在學(xué)習(xí)決策樹(shù)時(shí)运杭，對(duì)決策樹(shù)的存儲(chǔ)使用了這樣一段代碼
def storeTree(inputTree,filename):
import pickle
fw = open(filename,'w')
pickle.dump(inputTree,fw)
fw.close()
def grabTree(filename):
import pickle
fr = open(filename)
return pickle.load(fr)
于是可以看出Pickle模塊是用來(lái)進(jìn)行數(shù)據(jù)的本地存儲(chǔ)的瘟滨，其用法如下
