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.
Here's a Python function that finds words repeated 5 or more times using regex:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | import re def match(text): # Convert text to lowercase to make matching case-insensitive text = text.lower() # Find all words in the text words = re.findall(r'\b\w+\b', text) # Count occurrences of each word word_count = {} for word in words: word_count[word] = word_count.get(word, 0) + 1 # Check if any word appears 5 or more times for word, count in word_count.items(): if count >= 5: return word return "" |
1 2 3 4 5 6 7 8 | # Should return "the" print(match("The the the the the cat sat on the mat")) # Should return "dog" print(match("dog dog dog Dog DOG cat cat")) # Should return "" print(match("no words repeated five times here")) |
1 2 3 4 5 6 7 8 9 | from collections import Counter import re def match(text): words = re.findall(r'\b\w+\b', text.lower()) for word, count in Counter(words).items(): if count >= 5: return word return "" |
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 | import re def match(text): # Convert text to lowercase to make matching case-insensitive text = text.lower() # Find all words in the text words = re.findall(r'\b\w+\b', text) # Count occurrences of each word word_count = {} for word in words: word_count[word] = word_count.get(word, 0) + 1 # Check if any word appears 5 or more times for word, count in word_count.items(): if count >= 5: return word return "" |
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 | import re def match(text): # Convert text to lowercase to make matching case-insensitive text = text.lower() # Find all words in the text words = re.findall(r'\b\w+\b', text) # Count occurrences of each word word_count = {} for word in words: word_count[word] = word_count.get(word, 0) + 1 # Check if any word appears 5 or more times for word, count in word_count.items(): if count >= 5: return word return "" 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') |
