converting dictionary within a list to JSON format using python

Question

I have a dictionary within a list as below

b = [
    {
        "ServiceLevel": {
            "S": "AA"
        },
        "ReadyTime": {
            "S": "2020-01-31T12:00:00"
        },
        "DeliveryDate": {
            "S": "2020-02-15T12:00:00"
        }
    }
]

I am trying to access the elements within that inner dictionary and convert them to JSON format: My try:

a = b[0]
for key, value in sorted(a.items()):
    a1 = print(key, value)

for i in a1:
    b1 = a1[i]
    print(b1)

I am trying to get this output:

b = {   
        "ServiceLevel": "AA",
        "ReadyTime": "2020-01-31T12:00:00",
        "ReadyDate": "2020-01-31T12:00:00",    
}

ERROR : TypeError: 'NoneType' object is not callable

Answer 1

You are assigning print() method to a variable, here is the NoneType error

a1 = print(key, value) # variable a1 is NoneType
for i in a1: # error because variable a1 is not iterable

Use :

b1 = {}
for key, value in b[0].items():
    b1[key] = value['S']
print(b1)
