从作为字符串传递的值中获取数据类型

def get_data_type(value):
    if isinstance(value, int):
        return "整数"
    elif isinstance(value, float):
        return "浮点数"
    elif isinstance(value, str):
        return "字符串"
    elif isinstance(value, bool):
        return "布尔值"
    else:
        return "未知数据类型"

value = "123"
print(get_data_type(value))  # 输出：字符串
