使用python的json包保存加载json

import json

# save json
f = open('aa.json', 'w')
data1 = {'name':'john', "age":12}
data1["num"] = 1
data2 = {'name':'merry', "age":13}
data = [data1, data2]
print(data)
json.dump(data, f, ensure_ascii=False)
f.close()

# load json
print "----------"
f = open('aa.json', 'r')
s = json.load(f)
print "s:           ", s
print "s[0]:        ", s[0]
print 's[0]["name"]:', s[0]["name"]
