JSON, Javascript Object Notation is a widely used file format for data exchange all across the web thanks to the prevalence of Javascript frameworks.

So to search for a key, how do you select how "load/loads" will read the json file? i.e. how do you select it whether it reads it as a python string, dictionary, or list?

Do you have any recommendations on searching for a particular key, say a name in a contact list, and then if found, return the email or phone number for that name?

I'm getting confused, as I see things like :
for elem in
or
for elem in jdata:
if elem['symbol'] == "usd":
pprint (elem)

Or via recursive/generator functions?
def findall(v, k):

if type(v) == type({}):
for k1 in v:
if k1 == k:
print v[k1]
findall(v[k1], k)

findall(json.loads(a), 'P1')

Or via regular expression?
rex1 = \")[a-zA-Z_\- ]+(?=\")')
rex2 = rex1.findall(JSON)

Or xml's parseString?
