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.
To find a word that is repeated 5 times or more in a given string using regular expressions in Python, you can use the `re` module. Below is a function called `match` that implements this logic:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | import re def match(text): # Regex pattern to match any word repeatedly 5 or more times pattern = r'\b(\w+)\b(?=.*\b\1\b.*\b\1\b.*\b\1\b.*\b\1\b)' # Search for all matches in the text matches = re.findall(pattern, text) # Use a set to avoid duplicates and return only the first match if exists unique_matches = set(matches) if unique_matches: # Return the first matched word that meets the criteria return next(iter(unique_matches)) return '' # Example usage: input_text = "hello world hello hello hello hello hello" print(match(input_text)) # Output: 'hello' |
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 def match(text): # Regex pattern to match any word repeatedly 5 or more times pattern = r'\b(\w+)\b(?=.*\b\1\b.*\b\1\b.*\b\1\b.*\b\1\b)' # Search for all matches in the text matches = re.findall(pattern, text) # Use a set to avoid duplicates and return only the first match if exists unique_matches = set(matches) if unique_matches: # Return the first matched word that meets the criteria return next(iter(unique_matches)) return '' # Example usage: input_text = "hello world hello hello hello hello hello" print(match(input_text)) # Output: 'hello' |
Running the following program:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 | import re def match(text): # Regex pattern to match any word repeatedly 5 or more times pattern = r'\b(\w+)\b(?=.*\b\1\b.*\b\1\b.*\b\1\b.*\b\1\b)' # Search for all matches in the text matches = re.findall(pattern, text) # Use a set to avoid duplicates and return only the first match if exists unique_matches = set(matches) if unique_matches: # Return the first matched word that meets the criteria return next(iter(unique_matches)) return '' # Example usage: input_text = "hello world hello hello hello hello hello" print(match(input_text)) # Output: 'hello' answer = match('hi hi hi hi hi') expected = "hi" assert answer == expected, f'Wrong answer; got {answer} instead of {expected}' answer = match('hi hi hi hi') expected = "" assert answer == expected, f'Wrong answer; got {answer} instead of {expected}' answer = match('hello this is is is is is a test') expected = "is" assert answer == expected, f'Wrong answer; got {answer} instead of {expected}' print('All tests passed') |

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.
You can achieve this by using Python's `re` module, which provides support for regular expressions. Below is a function `match` that uses a regex pattern to find any word that is repeated 5 times or more in a given string. If such a word is found, it returns that word; otherwise, it returns an empty string. Here's how you can implement this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | import re def match(text): # Regex pattern to find words that are repeated 5 or more times pattern = r'\b(\w+)\b(?=.*\b\1\b.*\b\1\b.*\b\1\b.*\b\1\b)' # Find all matches in the text matches = re.findall(pattern, text) # Use a set to eliminate duplicates and check for any match unique_matches = set(matches) # Return the first match found, or empty string if none found return unique_matches.pop() if unique_matches else '' # Example usage: text = "hello hello hello hello hello world world world" result = match(text) print(result) # Output: hello |
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 | import re def match(text): # Regex pattern to find words that are repeated 5 or more times pattern = r'\b(\w+)\b(?=.*\b\1\b.*\b\1\b.*\b\1\b.*\b\1\b)' # Find all matches in the text matches = re.findall(pattern, text) # Use a set to eliminate duplicates and check for any match unique_matches = set(matches) # Return the first match found, or empty string if none found return unique_matches.pop() if unique_matches else '' # Example usage: text = "hello hello hello hello hello world world world" result = match(text) print(result) # Output: hello |
Running the following program:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 | import re def match(text): # Regex pattern to find words that are repeated 5 or more times pattern = r'\b(\w+)\b(?=.*\b\1\b.*\b\1\b.*\b\1\b.*\b\1\b)' # Find all matches in the text matches = re.findall(pattern, text) # Use a set to eliminate duplicates and check for any match unique_matches = set(matches) # Return the first match found, or empty string if none found return unique_matches.pop() if unique_matches else '' # Example usage: text = "hello hello hello hello hello world world world" result = match(text) print(result) # Output: hello answer = match('hi hi hi hi hi') expected = "hi" assert answer == expected, f'Wrong answer; got {answer} instead of {expected}' answer = match('hi hi hi hi') expected = "" assert answer == expected, f'Wrong answer; got {answer} instead of {expected}' answer = match('hello this is is is is is a test') expected = "is" assert answer == expected, f'Wrong answer; got {answer} instead of {expected}' print('All tests passed') |
