如何在输出随机json的代码中添加循环并将其保存在本地？

Question

wrote a code using faker library in python that generates random json strings. how to add another loop in it so ids will loop in ids place

import json 
from faker import Faker
import random
from random import randint

ids=(1,2,3,4,5,6)

print('{"data": [')
fake = Faker('en_US')
for _ in range(10):
    sms =  {
      "pid": "ABs-1cd",
      "body": fake.text(),
      "mime": fake.ean(),
      "hashed": fake.ean(),
      "celus": fake.ean(),
      "ids": "1", 
      "dev": "465p"
   }
    print(",")
    print(json.dumps(sms))

print('],"ids": "1"}') 

and save the json according to user id like in case 1.json,2.json,3.json,4.json

Answer 1

I think this is what you are looking for:

ids= (1, 2, 3, 4, 5, 6)

fake = Faker('en_US')

for ind in ids:
    cont = []
    for idx in range(10):
        sms =  {
            "pid": "ABs-1cd",
            "body": fake.text(),
            "mime": fake.ean(),
            "hashed": fake.ean(),
            "celus": fake.ean(),
            "ids": ind, 
            "dev": "465p"
        }
        cont.append(sms)

    f_name = '{}.json'.format(ind)
    with open(f_name, 'w') as fp:
        json.dump(cont, fp, indent=4)
        print('saved {}'.format(f_name))

The outer loop iterates over the numbers 1 until 6, where each outer-loop iteration generates <id_number>.json . The inner-loop creates 10 python dictionaries and saves them in a list called cont , which is emptied at the beginning of the outer loop.

Answer 2

To begin with, instead of the two print statement, you can append all dictionaries to a list, and then create your overall dictionary,

Also you can add another outer loop which loops through the indexes and picks id accordingly

import json 
from faker import Faker
import random
from random import randint

ids=[1,2,3,4,5,6]

data = {}
li = []

fake = Faker('en_US')
for idx in range(400):
    #Loop through id in ids
    id = ids[int(idx%6)]
    sms =  {
      "pid": "ABs-1cd",
      "body": fake.text(),
      "mime": fake.ean(),
      "hashed": fake.ean(),
      "celus": fake.ean(),
      "ids": id,
      "dev": "465p"
   }
    li.append(sms)

data['data'] = li
print(data)

The output will be
