python使用cPickle模块序列化实例

import cPickledata1 = ['abc',12,23]  #几个测试数据data2 = {1:'aaa',"b":'dad'}data3 = (1,2,4)output_file = open("a.txt",'w')cPickle.dump(data1,output_file)cPickle.dump(data2,output_file)cPickle.dump(data3,output_file)output_file.close()input_file = open('a.txt','rb')#data1 = []data1 = cPickle.load(input_file)data2 = cPickle.load(input_file)data3 = cPickle.load(input_file)print data1print data2print data3outstring = cPickle.dumps(data1)open('out.txt','wb').write(outstring)file_data = open('out.txt','rb').read()real_data = cPickle.loads(file_data)print real_data

['abc', 12L, 23L]{1L: 'aaa', 'b': 'dad'}(1L, 2L, 4L)['abc', 12L, 23L]
