对字段中的拆分字符串使用正则表达式，然后根据布尔结果使用case条件的问题

import re

def process_data(data):
    # 使用正则表达式拆分字符串
    pattern = r'(\w+):(\w+)'
    matches = re.findall(pattern, data)
    
    result = {}
    for key, value in matches:
        # 根据键的值应用CASE条件
        if key == 'key1':
            if value == 'value1':
                result[key] = 'Condition A met'
            else:
                result[key] = 'Condition A not met'
        elif key == 'key2':
            if value == 'value2':
                result[key] = 'Condition B met'
            else:
                result[key] = 'Condition B not met'
        else:
            result[key] = 'Unknown key'
    
    return result

# 测试数据
data = "key1:value1,key2:value2,key3:value3"
print(process_data(data))
