PROBLEM STATEMENT

x is an input list of dictionaries which needs to be formatted to y which is also a list of dictionaries , but in this case the key is pickupAddress and the sub dictionary consist of { zipcode,lat,long}

so basically , i want to transform x to y

Approach taken

1. have used tuples to store the values and then inserted to a list

code screenshot

deliveryAddress={}
pickupAddress={}
l1=[]
l2=[]
l1_del=[]
l2_pick=[]
for i in range(len(x)):
    k1=('zipcode',x[i]['delivery_zip'])
    l1.append(k1)
    k2=('longitude',x[i]['delivery_lng'])
    l1.append(k2)
    k3=('latitude',x[i]['delivery_lat'])
    l1.append(k3)
    
    k4=('zipcode',x[i]['latitude'])
    l2.append(k4)
    k5=('longitude',x[i]['longitude'])
    l2.append(k5)
    k6=('latitude',x[i]['zipcode'])
    l2.append(k6)
    
    t1=("pickupAddress",l1)
    t2=("deliveryAddress",l2)
    
    print(l1)
    print(l2)
    if i < len(x):
        print(len(x))
        l1_del.append(t1)
        l2_pick.append(t2)
        del l1
        del l2 
        
        l1=[]
        l2=[]

CodePudding user response：

To transform one list into another list, use a list comprehension:

y = [
        {
            "pickupAddress": { "zipcode": obj['zipcode'], "latitude": obj['latitude'], "longitude": obj['longitude']},
            "deliveryAddress": {"zipcode": obj['delivery_zip'], "latitude": obj['delivery_lat'], "longitude": obj['delivery_lng'] }
        }
        for obj in x
    ]
