Write a function called `match` in Python that uses a regex to find any word repeated 5 times or more. Return that word. If no word is repeated 5 times or more, return an empty string.
Here's a Python function called `match` that uses regular expressions (regex) to find any word repeated 5 times or more in a given text. If no word is repeated 5 times or more, the function returns an empty string.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | import re from collections import Counter def match(text): # Use regex to find all words in the text words = re.findall(r'\b\w+\b', text) # Count occurrences of each word word_count = Counter(words) # Find the first word that is repeated 5 times or more for word, count in word_count.items(): if count >= 5: return word # If no word is repeated 5 times or more, return an empty string return '' # Example usage text = "This is a test. This test is only a test. In the event of an actual emergency, the test word will be repeated test test test test test." print(match(text)) # Output: 'test' |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | import re from collections import Counter def match(text): # Use regex to find all words in the text words = re.findall(r'\b\w+\b', text) # Count occurrences of each word word_count = Counter(words) # Find the first word that is repeated 5 times or more for word, count in word_count.items(): if count >= 5: return word # If no word is repeated 5 times or more, return an empty string return '' # Example usage text = "This is a test. This test is only a test. In the event of an actual emergency, the test word will be repeated test test test test test." print(match(text)) # Output: 'test' |

Write a function called `match` in Python that uses a regex to find any word repeated 5 times or more. Return that word. If no word is repeated 5 times or more, return an empty string.
Certainly! To implement the `match` function in Python that uses regular expressions to find any word repeated 5 times or more, you can use the `re` module, which provides support for working with regular expressions. Here's a step-by-step implementation: 1. Import the `re` module. 2. Use a regular expression pattern to find words. 3. Count the occurrences of each word. 4. Return the word if it appears 5 times or more. Here's the code for the `match` function:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | import re from collections import Counter def match(text): # Define the regex pattern to find words pattern = r'\b\w+\b' # Find all words in the text words = re.findall(pattern, text) # Count the occurrences of each word word_counts = Counter(words) # Find any word repeated 5 times or more for word, count in word_counts.items(): if count >= 5: return word # If no word is repeated 5 times or more, return an empty string return "" # Example usage: text = "This is a test. This test is only a test. In the event of an actual emergency, the test would be followed by actual instructions. This test is a test." print(match(text)) # Output will depend on the input text |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | import re from collections import Counter def match(text): # Define the regex pattern to find words pattern = r'\b\w+\b' # Find all words in the text words = re.findall(pattern, text) # Count the occurrences of each word word_counts = Counter(words) # Find any word repeated 5 times or more for word, count in word_counts.items(): if count >= 5: return word # If no word is repeated 5 times or more, return an empty string return "" # Example usage: text = "This is a test. This test is only a test. In the event of an actual emergency, the test would be followed by actual instructions. This test is a test." print(match(text)) # Output will depend on the input text |
