如何在字典和google protobuf枚举中使用类型提示？

from typing import Dict

def process_data(data: Dict[str, int]) -> None:
    for key, value in data.items():
        print(f"Key: {key}, Value: {value}")

// example.proto
enum Color {
    RED = 0;
    GREEN = 1;
    BLUE = 2;
}

message ExampleMessage {
    Color color = 1;
}

from enum import Enum

class Color(Enum):
    RED = 0
    GREEN = 1
    BLUE = 2

class ExampleMessage:
    def __init__(self, color: Color):
        self.color = color

from typing import Dict, List, Tuple

def process_nested_data(data: Dict[str, List[Tuple[int, str]]]) -> None:
    for key, values in data.items():
        for value in values:
            print(f"Key: {key}, Value: {value}")

from enum import Enum

class CustomEnum(Enum):
    VALUE1 = "value1"
    VALUE2 = "value2"

// example.proto
enum CustomEnum {
    VALUE1 = 0;
    VALUE2 = 1;
}

message ExampleMessage {
    CustomEnum custom_enum = 1;
}
