When appending dictionary to a list, dict. not on a new line each time

问题

I have this function that pushes a dictionary created by another function, to a list. The problem I'm having with my code is that multiple pushes do not show up in the list each in a new line. I've tried many ways, but none have given me the desired results.

This is the line the pushes the created dictionary:

Database.xoomDatabase.append(ordenOrganiz)

This function creates the dictionary:

def orderZoom(self):
        nombre = contents1
        nicenum = orderResult
        email = contents2
        num = contents3
        fechaentrega = contents5

        global ordenOrganiz
        ordenOrganiz = {"Num Orden": nicenum,
                        "Nombre": nombre, 
                        "Email": email,
                        "Num Tel/Cel": num,
                        "Fecha de Entrega": fechaentrega}
        return ordenOrganiz

Any ideas on getting this done?

Sounds like your problem is not the inserts but rather the "pretty print" that you want to apply, check out the following example that uses json.dumps:

import json

ordenOrganiz = {"Num Orden": 1,
                "Nombre": 2, 
                "Email": 3,
                "Num Tel/Cel": 4,
                "Fecha de Entrega": 5}
lst = []
lst.append(ordenOrganiz)                
lst.append(ordenOrganiz)                

print json.dumps(lst, indent=4, separators=(',', ': '))

OUTPUT

[
    {
        "Fecha de Entrega": 5,
        "Nombre": 2,
        "Num Tel/Cel": 4,
        "Num Orden": 1,
        "Email": 3
    },
    {
        "Fecha de Entrega": 5,
        "Nombre": 2,
        "Num Tel/Cel": 4,
        "Num Orden": 1,
        "Email": 3
    }
]
