如何在循环的开头和结尾添加两个字符串而不循环它们
代码：

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

ids= (1, 2)

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))

如何首先添加

 ('{"first":')

最后是

('{",user_id":ids}')

无需在循环中循环这两个字符串。

Answer 1

使用first和user_ids键制作一个整体字典，并使用该字典将cont列表保存到第一键，并将ind保存到user_ids键

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

ids= (1, 2)

fake = Faker('en_US')

for ind in ids:
    cont = []
    #Overall dictionary with first and user_ids
    dct = {}
    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)
    #Use a dictionary to save cont list to first key, and ind to user_ids key
    dct['first'] = cont
    dct['user_ids'] = ind
    print(dct)
    f_name = '{}.json'.format(ind)
    with open(f_name, 'w') as fp:
        #Save the dictionary
        json.dump(dct, fp, indent=4)
        print('saved {}'.format(f_name))

输出将为
