Add a # to beginning of each key in Json Python2.7 - json

Question

I'm trying to add a "#" at the beginning to each key of a Json object (got it from RabbitMQ api calls)
here is my attempt :
#!/bin/python
# Libraries import
import requests
import json
import sys
import os
# Define URLs
overview="/api/overview"
nodes="/api/nodes"
queues="/api/queues"
# Get credentials from file
with open('/credentials') as json_file:
data = json.load(json_file)
user = data['user']
passwd = data['pass']
# Test which URL we want to call
if ''.join(sys.argv[1]) == "overview":
commande=overview
if ''.join(sys.argv[1]) == "queues":
commande=queues
if ''.join(sys.argv[1]) == "nodes":
commande=nodes
def append(mydict):
return dict(map(lambda (key, value): ("#"+str(key), value), mydict.items()))
def transform(multileveldict):
new = append(multileveldict)
for key, value in new.items():
if isinstance(value, dict):
new[key] = transform(value)
return new
def upper_keys(x):
if isinstance(x, list):
return [upper_keys(v) for v in x]
elif isinstance(x, dict):
return dict((k.upper(), upper_keys(v)) for k, v in x.iteritems())
else:
return x
# Main
response = requests.get("http://localhost:15672" + commande, auth=(user, passwd))
if(response.ok):
json_data = json.loads(response.content)
json = json.dumps(upper_keys(json_data), indent=4)
print(json)
Here is the JSON that I get in "response.content" :

Here, I made every key in uppercase and can display it has JSON but can't find anything to add this "#" to the beginning of each key
PS : I'm new to Python development
Thank you very much

Answer 1

Since you mentioned that you have successfully converted every keys in a dictionary into upper case keys, why don't you reuse the method and change the part where you do upper case into prepending "#"
# the one you provided
def upper_keys(x):
if isinstance(x, list):
return [upper_keys(v) for v in x]
elif isinstance(x, dict):
return dict((k.upper(), upper_keys(v)) for k, v in x.iteritems())
else:
return x
# the modified method
def prepend_hash_keys(x):
if isinstance(x, list):
return [prepend_hash_keys(v) for v in x]
elif isinstance(x, dict):
# this part from k.upper() to "#" + k
return dict(("#" + k, prepend_hash_keys(v)) for k, v in x.iteritems())
else:
return x

Your transform function actually works fine (for Python 2), you just forgot to actually call it! Instead, you call only upper_keys, but not transform:
json = json.dumps(upper_keys(json_data), indent=4) # where's transform?
If you use both one after the other (order does not matter) it should work:
json = {"nested": {"dict": {"with": {"lowercase": "keys"}}}}
print(transform(upper_keys(json)))
# {'#NESTED': {'#DICT': {'#WITH': {'#LOWERCASE': 'keys'}}}}
However, both transform and upper_keys can be simplified a lot using dictionary comprehensions (also available in Python 2), and you can combine both in one function:
def transform_upper(d):
if isinstance(d, dict):
return {"#" + k.upper(): transform_upper(v) for k, v in d.items()}
else:
return d
print(transform_upper(json))
# {'#NESTED': {'#DICT': {'#WITH': {'#LOWERCASE': 'keys'}}}}

Answer 3

From the look of it you already tried something like that in append() function.
If you modify that a bit to have something like this, it may do what you are looking for:
mydict = {
'name':1,
'surname':2
}
def append(mydict):
new_dict = {}
for key, val in mydict.items():
new_dict['#'+key]=val
return new_dict
print(append(mydict))
