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('./data1/data.json', encoding='utf-8') as f:
    a = json.load(f)   # a为data.json中的内容
    value1 = a['data']     # value1为a中'data'对应的value值为列表，里面有多个字典
    list1 = []
    dict2 = {}
    for dict1 in value1:    # 遍历value1中的每个字典出来
        for key1 in dict1:
            if key1 == 'name':
                # dict2 = dict1.pop(key1)
                dict2[key1] = dict1[key1]
                list1.append(dict2)
            elif key1 == 'text':
                dict2[key1] = dict1[key1]
                list1.append(dict2)
            elif key1 == 'love':
                dict2[key1] = dict1[key1]
                list1.append(dict2)
            elif key1 == 'comment':
                dict2[key1] = dict1[key1]
                list1.append(dict2)
    print(list1)
with open('./data1/new_data.json', 'w', encoding='utf-8') as g:
    json.dump(list1, g)
    print(g)

2. 统计data.json中comment数量超过1000的个数

import json
with open('./data1/data.json', encoding='utf-8') as f:
    a = json.load(f)   # a为data.json中的内容
    value1 = a['data']     # value1为a中'data'对应的value值为列表，里面有多个字典
    num1 = 0
    for dict1 in value1:
        if dict1['comment'] >= '1000':
           num1 += 1
    print(num1)

3. 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

with open('./data1/data.json', encoding='utf-8') as f:
    a = json.load(f)   # a为data.json中的内容
    value1 = a['data']     # value1为a中'data'对应的value值为列表，里面有多个字典
    for dict1 in value1:
        if dict1['love'] >= '1000':
            print(dict1['love'])

4. 写猜数字游戏，如果输入有误，提示重新输入，直达输入正确为止。比如：输入数字的时候没有按要求输入，提示重新输入

while True:
    try:
        num1 = int(input('请输入数字：'))
    except:
        input('重新输入')
