在 Python 中,虽然没有像 TypeScript 或其他语言中的显式泛型支持,但可以通过使用"类型提示"和"typevar"来实现类似的泛型行为。下面是一个使用类型提示和"typevar"的示例:
from typing import TypeVar, List
T = TypeVar('T') # 定义一个泛型类型变量
def reverse_list(lst: List[T]) -> List[T]:
return lst[::-1]
# 使用泛型函数
numbers = [1, 2, 3, 4, 5]
reversed_numbers = reverse_list(numbers)
print(reversed_numbers) # 输出: [5, 4, 3, 2, 1]
names = ["Alice", "Bob", "Charlie"]
reversed_names = reverse_list(names)
print(reversed_names) # 输出: ["Charlie", "Bob", "Alice"]
在上面的示例中,T = TypeVar('T')创建了一个泛型类型变量T。然后,我们定义了一个名为reverse_list的函数,它接受一个列表(List)类型的参数lst,并返回一个相同类型的列表。函数内部使用[::-1]语法来反转列表的顺序。
通过将List[T]作为函数参数的类型提示,我们表明lst参数可以是任意类型的列表。这样,我们可以在函数调用时传递不同类型的列表,并得到正确的结果。
在上面的示例中,我们分别传递了一个整数列表和一个字符串列表,并成功地得到了反转后的列表。这展示了使用类型提示和"typevar"实现泛型函数的能力。
