python保存多变量至本地二进制文件

导入pickle包

import pickle
data={"aaa":1,"bbb":2,"ccc":[1,2,3]}
data2={"aaa":1,"bbb":2,"ccc":[2,2,3]}

两个变量相继存入文件中

save_file=open("save.bin","wb")
pickle.dump(data,save_file)#顺序存入变量
pickle.dump(data2,save_file)
save_file.close()

然后顺序读出两个变量，多变量存入的时候，dump顺序与load顺序一致

load_file=open("save.bin","rb")
data3=pickle.load(load_file)#顺序导出变量
data4=pickle.load(load_file)
print(data3,data4)
