如何保存使用子进程循环python脚本的脚本的输出？

Question

如何保存循环python脚本的python脚本的输出

from datetime import datetime
import faker
import json
from faker import Faker
import random
from random import randint
import subprocess
import json
import os
from pprint import pprint
import subprocess
import sys


for i in range(20):
    subprocess.call(['python','curlloop1.py'])

此代码循环生成随机 json 文件的 python 脚本。每次循环时我都需要保存输出..

curl.py 代码生成随机 json 并将输出保存到 json 文件

import faker
import json
from faker import Faker
import random
from random import randint
import subprocess
import json
import os
#subprocess.call([""])
from pprint import pprint

ids= ('5cda','7f36')

fake = Faker('en_US')

for ind in ids:
    cont = []
    #Overall dictionary with first and user_ids
    dct = {}
    for idx in range(20):


        sms =  {
            "id":"AB-Iasd",
            "body": fake.sentence(),
            "reae": fake.ean(),
            "ashe": fake.ean(),
            "id2": fake.ean(),
            "user_id": ind,
            "pid": fake.sentence()
        }
        cont.append(sms)
    #Use a dictionary to save cont list to first key, and ind to user_ids key
    dct['messages'] = cont
    dct['user_id'] = 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))

除了在另一个文件中循环外部文件curlloop1.py，您只需添加一个运行 20 次的整体 for 循环，将所有字典收集到一个列表中，然后将该列表作为字典保存在单个文件中

import faker
import json
from faker import Faker
import random
from random import randint
import subprocess
import json
import os
#subprocess.call([""])
from pprint import pprint

ids= ('5cda','7f36')

fake = Faker('en_US')

msg_list = []

#Overall loop to run inner loop 20 times
for _ in range(20):
    #Loop to generate messages
    for ind in ids:
        cont = []
        #Overall dictionary with first and user_ids
        dct = {}
        for idx in range(20):


            sms =  {
                "id":"AB-Iasd",
                "body": fake.sentence(),
                "reae": fake.ean(),
                "ashe": fake.ean(),
                "id2": fake.ean(),
                "user_id": ind,
                "pid": fake.sentence()
            }
            cont.append(sms)
        #Use a dictionary to save cont list to first key, and ind to user_ids key
        dct['messages'] = cont
        dct['user_id'] = ind
        msg_list.append(dct)


#Saving overall data to a single dictionary and to a file
data = {"data":msg_list}

f_name = 'data.json'
with open(f_name, 'w') as fp:
    #Save the dictionary
    json.dump(data, fp, indent=4)
    print('saved {}'.format(f_name))

data.json 看起来像

{
    "data": [
        {
            "messages": [
                {
                    "id": "AB-Iasd",
                    "body": "Up west accept third success bad.",
                    "reae": "0181541986524",
                    "ashe": "1490107025812",
                    "id2": "4087146706078",
                    "user_id": "5cda",
                    "pid": "Color wish method population affect."
                },
                {
                    "id": "AB-Iasd",
                    "body": "Human expect news son room recognize beautiful.",
                    "reae": "9417635708941",
                    "ashe": "0920108608482",
                    "id2": "8218562976929",
