Awesome! Thank you!!

I am trying to add a key value pair of ("Priority":"1") to queue1, ("Priority":"2") to queue2, and
("Priority":"3") to queue3.
When I just add ("Priority":"1") to queue1, it works.
But when I run the above code, ("Priority":"3") is being added to all the
queues.
This looks trivial and I don't understand why this is happening. Is there
something wrong with what I am doing?
json_split = {}
value = {"Status": "Submitted", "m_Controller": "Python"}
a = range(31)
del a[0]
That's better as:
a = range(1, 31)
for i in a:
json_split[i] = value
Here the key will be whatever 'i' refers to (1..30) and the value will
be the dict referred to by 'value'.
Try adding the line:
print json_split[1] is json_split[2]
It'll print out 'True'; it's saying that they are the same dict.
You want the values of json_split to be _separate_ dicts.
The fix is simple. Just make a copy of the dict for each one:
for i in a:
json_split[i] = dict(value)

Problem adding a Key Value pair
I am trying to add a key value pair of ("Priority":"1") to queue1,
("Priority":"2") to queue2, and ("Priority":"3") to queue3.
When I just add ("Priority":"1") to queue1, it works.
But when I run the above code, ("Priority":"3") is being added to all the
queues.
This looks trivial and I don't understand why this is happening. Is there
something wrong with what I am doing?
json_split = {}
value = {"Status": "Submitted", "m_Controller": "Python"}
a = range(31)
del a[0]
for i in a:
json_split[i] = value
keys = json_split.keys()
order = list(keys)
q1 = int(round(len(keys)*0.2))
q2 = int(round(len(keys)*0.3))
q3 = int(round(len(keys)*0.5))
b = [q1,q2,q3]
n=0
threedicts = []
for i in b:
queues = order[n:n+i]
n = n+i
lists = [(queues[j], json_split.get(queues[j])) for j in
range(len(queues))]
onedict = {}
for q in queues:
onedict[q] = json_split[q]
threedicts.append (onedict)
queue1, queue2, queue3 = threedicts
keys1 = queue1.keys()
for i in keys1:
queue1[i]['Priority'] = ['1']
keys2 = queue2.keys()
for j in keys2:
queue2[j]['Priority'] = ['2']
keys3 = queue3.keys()
for z in keys3:
queue3[z]['Priority'] = ['3']
