1.提取data.json中的数据，将每条数据中的name、text、love和comment信息。并且保存到另外一个json文件中

•  import json
  with open('.\data.json','r',encoding='utf-8') as f:
      con = json.load(f)
  new = []
  a = {}
  for x in con['data']:
      a = {'name': x['name'], 'text': x['text'], 'love': x['love'], 'comment':                                             x['comment']}
      new.append(a)
  
  
  with open('.\json1.json', 'w', encoding='utf-8') as c:
      json.dump(new,c)
  

2. 统计data.json中comment数量超过1000的个数和它们的和

• import json
  with open('.\data.json','r',encoding='utf-8') as f:
      con = json.load(f)
  y = 0
  comment0 = 0
  for x in con['data']:
      y += int(x['comment'])
      if int(x['comment']) > 1000:
          comment0 += 1
  print('超过1000：',comment0)
  print('和： ',y)
  

将data.json文件中所有点赞数(love)对应的值超出1000的用k来表示，例如1000修改为1k, 1345修改为1.3k

• import json
  with open('.\data.json','r',encoding='utf-8') as f:
        con = json.load(f)
    love1 = 0
  for x in con['data']:
      if int(x['love']) >=1000:
          love1 = int(x['love']) / 1000
          wee=str('%.1fk'%(love1))
          x['love'] = wee
          print(wee)
  
  with open('.\data1.json','w',encoding='utf-8') as fd:
      json.dump(con,fd)
