import json

name_emb = {'a': '1111', 'b': '2222', 'c': '3333', 'd': '4444'}

jsDumps = json.dumps(name_emb)
jsLoads = json.loads(jsDumps)

print(name_emb)
print(jsDumps)
print(jsLoads)

print(type(name_emb))
print(type(jsDumps))
print(type(jsLoads))

print("=================================================")

emb_filename = ('emb_json.json')
# solution 1
jsObj = json.dumps(name_emb)
with open(emb_filename, "w") as f:
    f.write(jsObj)
    f.close()
# solution 2
json.dump(name_emb, open(emb_filename, "w"))


jsObj = json.load(open(emb_filename))
print(jsObj)
print(type(jsObj))
for key in jsObj.keys():
    print('key: %s  value: %s' % (key, jsObj.get(key)))
