Python办公自动化之JSOM数据处理与SQL Server数据库操作

import json

# JSON字符串
json_data = '{"name": "John", "age": 30, "city": "New York"}'

# 解析JSON数据
data = json.loads(json_data)

# 访问数据
print(data["name"]) # 输出：John
print(data["age"]) # 输出：30

import json

# Python字典
data = {
	"name": "John",
	"age": 30,
	"city": "New York"
	}
	
# 将数据转换为JSON字符串
json_data = json.dumps(data)

# 输出JSON字符串
print(json_data) # 输出：{"name": "John", "age": 30, "city": "New York"}

import json

# 从JSON⽂件读取数据
with open("data.json", "r") as json_file:
	data = json.load(json_file)

# 访问数据
print(data["name"])

import json

# Python字典
data = {
	"name": "John",
	"age": 30,
	"city": "New York"
	}

# 将数据写⼊JSON⽂件
with open("data.json", "w") as json_file:
	json.dump(data, json_file)

import json

# 嵌套的JSON数据
json_data = '{"person": {"name": "John", "age": 30}}'

# 解析JSON数据
data = json.loads(json_data)

# 访问嵌套数据
print(data["person"]["name"]) # 输出：John
