# coding = utf-8
import pickle
#定義一個boy類
class boy():
def __init__(self,name,age):
self.name = name
self.age = age
self.gf_dic = {}
#創建實例對象
b = boy('李明',23)
f = open("a.text",'wb')
pickle.dump(b,f)
b1 = pickle.load(open("a.text",'rb'))
print(b1.gf_dic)
b1.gf_dic[1] = {b:'秀秀'}
b1.gf_dic[2] = {b:'麗麗'}
pickle.dump(b1,f)
解決：（分段執行）
1 # coding = utf-8 2 import pickle 3 #定義一個boy類 4 class boy(): 5 def __init__(self,name,age): 6 self.name = name 7 self.age = age 8 self.gf_dic = {} 9 #創建實例對象 10 b = boy('李明',23) 11 # f = open("a.text",'wb') 12 # pickle.dump(b,f) 13 # f.close() 14 print(b.gf_dic) 15 16 f1 = open("a.text",'rb') 17 b1 = pickle.load(f1) 18 f1.close() 19 print(b1.gf_dic) 20 # b1.gf_dic[1] = {b:'秀秀'} 21 # b1.gf_dic[2] = {b:'麗麗'} 22 # f2 = open("a.text",'wb') 23 # pickle.dump(b1,f2) 24 # f2.close()
結果：
