如何显示JSON数据中匹配字符串的长度？

{
  "name": "John",
  "age": 30,
  "city": "New York",
  "skills": ["Python", "JavaScript", "SQL"]
}

import json

# JSON字符串
json_data = '{"name": "John", "age": 30, "city": "New York", "skills": ["Python", "JavaScript", "SQL"]}'

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

# 查找字符串"John"的长度
name_length = len(data["name"])

print(f"The length of the name '{data['name']}' is {name_length}.")

try:
    data = json.loads(json_data)
    if "name" in data:
        name_length = len(data["name"])
        print(f"The length of the name '{data['name']}' is {name_length}.")
    else:
        print("Key 'name' not found in JSON data.")
except json.JSONDecodeError as e:
    print(f"Failed to decode JSON: {e}")
