避免重复性的泛化函数

from abc import ABC, abstractmethod

    @abstractmethod
    def print_data(self, data):
        pass

class StringPrinter(Printer):

class IntegerPrinter(Printer):
    def print_data(self, data):

def print通用函数(printer, data):
    printer.print_data(data)

# 使用示例
string_printer = StringPrinter()

print通用函数(string_printer, "Hello World")
print通用函数(integer_printer, 123)

        else:
            raise ValueError("Unsupported data type")

# 使用示例
print通用函数_v2("Hello World")
