序言

写在前面

实现结果

1 数据拉取

import json
import requests


def request_get(url, param):
    fails = 0
    while True:
        try:
            if fails >= 20:
                break

            ret = requests.get(url=url, params=param, timeout=10)

            if ret.status_code == 200:
                text = json.loads(ret.text)
            else:
                continue
        except:
            fails += 1
            print('网络连接出现问题, 正在尝试再次请求: ', fails)
        else:
            break
    return text


def request_post(url, param):
    fails = 0
    while True:
        try:
            if fails >= 20:
                break

            # headers = {'content-type': 'application/json'}
            ret = requests.post(url, json=param, timeout=10)

            if ret.status_code == 200:
                text = json.loads(ret.text)
            else:
                continue
        except:
            fails += 1
            print('网络连接出现问题, 正在尝试再次请求: ', fails)
        else:
            break
    return text

2 数据清洗、去重


import json

def getData():
    with open("data.json", 'r') as f:
        temp = json.loads(f.read())

        templist = temp['data']['list']
        user = []
        for i in templist:
            temp={
                'nickName':i['info']['nickName'],
                'avatar':i['info']['avatar']

            }
            user.append(temp)

        result = [dict(t) for t in set([tuple(d.items()) for d in user])]
        print(result)
        print(len(result))
        return result


if __name__ == '__main__':
    getData()

 result = [dict(t) for t in set([tuple(d.items()) for d in user])]

3 中奖数据抽取

import random

from giftchoose.userData import getdata


def getgift():
    num = getdata() # 用于存放抽奖用户信息
    print("欢迎来到抽奖小程序！")
    print("参与抽奖的用户如下：")
    for i in num:
        print(i)
    usernum = len(num)
    reward = 2
    usernum = int(usernum)
    reward = int(reward)

    resultList = []                         # 用于存放随机数结果
    def generateRand(counter):
        tempInt = random.randint(0, usernum-1)     # 生成一个范围内的临时随机数
        if(counter <= reward):                   # 先看随机数的总个数是不是够了，如果不够
            if(tempInt not in resultList):  # 再检查当前已经生成的临时随机数是不是已经存在
                resultList.append(tempInt)  # 如果不存在，则将其追加到结果resultList中
                counter += 1                # 然后将表示有效结果的个数加1
            generateRand(counter)           # 不管上面的if是否成立，都要递归。
    generateRand(1)                    # 调用递归函数，并给当前要生成的有效随机数的个序号置为1

    prize = []                              # 用于存放中奖号码
    # 将中奖号码添加到结果prize中
    for j in range(reward):
        prize.append(num[resultList[j]])
    print("\n中奖用户：")           # 输出中奖结果
    for k in range(reward):
        print(prize[k], end="\n")

if __name__ == '__main__':
    getgift()
