Python中，對(duì)象也可以按文本方式存儲(chǔ)到文件中，對(duì)應(yīng)包為pickle

#encoding:utf8
import pickle

class Test(object):
    a = 1

# 實(shí)例化對(duì)象，并進(jìn)行存儲(chǔ)
mTest = Test()
pickleStr = pickle.dumps(mTest)
f = open("file.txt","w")
f.write(pickleStr)

# 從文件中取出對(duì)象
f = open("file.txt","r")
str = f.read()    
mTest = pickle.  loads(str)

存儲(chǔ)也可以采用dump方法，免去了寫(xiě)這一行代碼

mTest = Test()
f = open("file.txt","w")
pickle.dump(mTest,f)

同樣，讀取可采用load方法

f = open("file.txt","r")
mTest = pickle.  loads(f)

還有一個(gè)包 cPickle，使用方法和pickle一樣，速度比 pickle快1000倍。導(dǎo)包時(shí)，只需使用import cPickle as pickle即可
