Implement about, which takes a list of topic words. It returns a function that can be passed to choose as the select argument. The returned function takes a paragraph and returns a boolean indicating whether that paragraph contains any of the words in topic. To make this comparison accurately, you will need to ignore case (that is, assume that uppercase and lowercase letters don't change what word it is) and punctuation. Assume that all words in the topic list are already lowercased and do not contain punctuation.

Sure, I can help you with that.
Here's an implementation of the `about` function you described:
```python
import string
def about(topic):
def contains_topic_word(paragraph):
# Remove punctuation from paragraph
paragraph = paragraph.translate(str.maketrans('', '', string.punctuation))
# Convert paragraph to lowercase
paragraph = paragraph.lower()
# Check if any word in the paragraph is in the topic list
for word in paragraph.split():
if word in topic:
return True
return False
return contains_topic_word
```
This function takes a list of topic words and returns a function that can be passed to the `choose` function's `select` argument. The returned function takes a paragraph and returns a boolean indicating whether that paragraph contains any of the words in the topic list. It removes punctuation from the paragraph, converts it to lowercase, and checks if any word in the paragraph is in the topic list.
Here's an example usage of this function:
```python
topic = ['python', 'programming', 'language']
contains_topic_word = about(topic)
paragraph = "Python is a high-level programming language. It is widely used for web development, scientific computing, data analysis, artificial intelligence, and more."
if contains_topic_word(paragraph):
print("This paragraph is about Python programming language.")
else:
print("This paragraph is not about Python programming language.")
```
Output:
```
This paragraph is about Python programming language.
```
I hope this helps! Let me know if you have any questions.
