#----------------------------Serialization
import json
 
dic={'name':'alvin','age':23,'sex':'male'}
print(type(dic))#<class 'dict'>
 
j=json.dumps(dic)
print(type(j))#<class 'str'>
 
 
f=open('Serialized object','w')
f.write(j) #-------------------equivalent to json.dump(dic,f)
f.close()
#-----------------------------Deserialization<br>
import json
f=open('serialize object')
data=json.loads(f.read())# is equivalent to data=json.load(f)

 

import json
#dct="{'1':111}"#json does not recognize single quotes
#dct=str({"1":111})#Error, because the generated data is still single quotes: {'one': 1}

dct='{"1":"111"}'
print(json.loads(dct))

#conclusion:
# No matter how the data is created, as long as it meets the json format, it can be json.loads out, not necessarily the data of dumps to load
