使用RegEx拆分字符串，将子字符串存储在映射中的分隔符内，以创建键值对

import re

def split_string(string):
    pattern = r'([^:]+):([^:]+)'
    matches = re.findall(pattern, string)
    result = {}
    for match in matches:
        key = match[0]
        value = match[1]
        result[key] = value
    return result

# 示例用法
string = "name:John age:25 city:New York"
result = split_string(string)
print(result)

{'name': 'John', 'age': '25', 'city': 'New York'}
