如何从文本字段中获取值

import json

json_str = '{"name": "John", "age": 30, "city": "New York"}'
data = json.loads(json_str)

name = data["name"]
age = data["age"]
city = data["city"]

print(name, age, city)

import xml.etree.ElementTree as ET

xml_str = '<person><name>John</name><age>30</age><city>New York</city></person>'
root = ET.fromstring(xml_str)

name = root.find("name").text
age = root.find("age").text
city = root.find("city").text

print(name, age, city)

import csv
from io import StringIO

csv_str = 'name,age,city\nJohn,30,New York'
csv_file = StringIO(csv_str)

reader = csv.DictReader(csv_file)
for row in reader:
    name = row["name"]
    age = row["age"]
    city = row["city"]

    print(name, age, city)

text = "name: John, age: 30, city: New York"

name = text.split(",")[0].split(":")[1].strip()
age = text.split(",")[1].split(":")[1].strip()
city = text.split(",")[2].split(":")[1].strip()

print(name, age, city)
