给定一段Python代码，使用正则表达式查找其中的所有注释。
code = '''
def add_numbers(a, b):
    # This is a comment
    """
    This is a multi-line
    comment
    """
    c = a + b
    # Another comment
    return c
'''
# TODO: Write code to find all comments in the code.
可以使用以下正则表达式查找Python中的所有注释：
```python
import re

code = '''
def add_numbers(a, b):
    # This is a comment
    """
    This is a multi-line
    comment
    """
    c = a + b
    # Another comment
    return c
'''

comments_regex = re.findall(r'\#.*|\'''\'.*?\'''', code, re.DOTALL | re.MULTILINE)
print(comments_regex)
```

输出：
```
['# This is a comment', '
    """
    This is a multi-line
    comment
    """', '# Another comment']
```
