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.
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 use the `re` module in Python to work with regular expressions. Here's how you could write the `match` function:
1 2 3 4 5 6 7 8 | import re def match(text): words = re.findall(r'\b\w+\b', text) # Find all words for word in set(words): # Iterate over unique words if words.count(word) >= 5: # If a word is repeated 5 times or more return word return '' # If no word is repeated 5 times or more |
1 2 3 4 | def match(text): text = text.lower() words = re.findall(r'\b\w+\b', text) # ... rest of the function ... |
1 2 3 4 5 | import re def match(text): words = re.findall(r'\b[a-z]+\b', text, re.IGNORECASE) # ... rest of the function ... |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 | import re def match(text): words = re.findall(r'\b\w+\b', text) # Find all words for word in set(words): # Iterate over unique words if words.count(word) >= 5: # If a word is repeated 5 times or more return word return '' # If no word is repeated 5 times or more |
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 | import re def match(text): words = re.findall(r'\b\w+\b', text) # Find all words for word in set(words): # Iterate over unique words if words.count(word) >= 5: # If a word is repeated 5 times or more return word return '' # If no word is repeated 5 times or more 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.
Here is a possible solution using the `re` module for regex in Python:
1 2 3 4 5 6 7 8 | import re def match(text): words = re.findall(r'\b\w+\b', text) # find all words in the text for word in set(words): # for each unique word if words.count(word) >= 5: # if it appears 5 or more times return word # return that word return "" # if no such word is found, return an empty string |
1 2 3 4 5 6 | >>> match("The quick brown fox jumps over the lazy dog.") '' >>> match("I love love love love love programming.") 'love' >>> match("To be or not to be, that is the question.") '' |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 | import re def match(text): words = re.findall(r'\b\w+\b', text) # find all words in the text for word in set(words): # for each unique word if words.count(word) >= 5: # if it appears 5 or more times return word # return that word return "" # if no such word is found, return an empty string |
