上述代码的输入输出应为>>> chocola = NoisyCat('Chocola', 'Minazuki Kashou') >>> isinstance(chocola, Cat) # check if chocola is an instance of Cat. True >>> chocola.talk() Chocola says meow! Chocola says meow!

Yes, that's correct! Here's how the input-output interaction would look like:
```
>>> chocola = NoisyCat('Chocola', 'Minazuki Kashou')
>>> isinstance(chocola, Cat) # check if chocola is an instance of Cat.
True
>>> chocola.talk()
Chocola says meow! Chocola says meow!
```
As you can see, the `NoisyCat` class is an instance of `Cat` (since it inherits from it), and the `talk` method of `NoisyCat` talks twice as much as the `talk` method of `Cat`.

## Problem 3: Noisy Cat More cats! Fill in this implemention of a class called `NoisyCat`, which is just like a normal `Cat`. However, `NoisyCat` talks a lot -- twice as much as a regular `Cat`! We may change the implementation of `Pet` and `Cat` while testing your code, so make sure you use inheritance correctly. ```python class NoisyCat: # Dose this line need to change? """A Cat that repeats things twice. >>> chocola = NoisyCat('Chocola', 'Minazuki Kashou') >>> isinstance(chocola, Cat) # check if chocola is an instance of Cat. True >>> chocola.talk() Chocola says meow! Chocola says meow! """ def __init__(self, name, owner, lives=9): # Is this method necessary? If not, feel free to remove it. "*** YOUR CODE HERE ***" def talk(self): """Talks twice as much as a regular cat. """ "*** YOUR CODE HERE ***" ``` ##
To create a `NoisyCat` class that inherits from `Cat` and talks twice as much as a regular `Cat`, we can simply override the `talk` method in `Cat` as follows:
```python
class NoisyCat(Cat):
def talk(self):
"""Talks twice as much as a regular cat.
"""
super().talk()
super().talk()
```
Here, we first call the `talk` method of the parent class `Cat` using `super().talk()`, and then call it again to make the `NoisyCat` talk twice as much as a regular `Cat`.
We can then test the implementation as follows:
```python
>>> chocola = NoisyCat('Chocola', 'Minazuki Kashou')
>>> isinstance(chocola, Cat)
True
>>> chocola.talk()
Chocola says meow!
Chocola says meow!

pycharm控制台中文显示unicode \xe6\x9d\x8e\xe7\x99\xbd\xe9\xa3\x9e码问题
当在PyCharm控制台中打印中文时,有时会出现Unicode编码的问题,导致中文无法正常显示。解决这个问题的方法有很多种,以下是其中一种方法:
在PyCharm的控制台中,可以使用`sys.stdout.encoding`命令来查看当前控制台的编码格式。如果编码格式为`UTF-8`,则可以使用以下代码解决中文显示问题:
```python
import sys
sys.stdout.reconfigure(encoding='utf-8')
```
如果编码格式为`GBK`或`GB2312`,则可以使用以下代码解决中文显示问题:
```python
import sys
sys.stdout.reconfigure(encoding='gbk')
```
```python
import sys
sys.stdout.reconfigure(encoding='gb2312')
```
如果以上方法无法解决问题,可以尝试使用以下代码:
```python
import io
import sys
sys.stdout = io.TextIOWrapper(sys.stdout.buffer, encoding='utf-8')
```
以上代码将标准输出流的编码格式设置为`UTF-8`,可以解决中文显示问题。
