userdata = { "data":[]}
def fil_userdata():
for i in xrange(0,5):
user = {}
user["name"]=...
user["age"]=...
user["country"]=...
add_user(user)
def add_user(user):
userdata["data"].append(user)
或更短：
def gen_user():
return {"name":"foo", "age":22}
userdata = {"data": [gen_user() for i in xrange(0,5)]}
# or fill separated from declaration so you can fill later
userdata ={"data":None} # None: not initialized
userdata["data"]=[gen_user() for i in xrange(0,5)]
