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.

Output

Certainly! Below is the Python function `match` that utilizes a regular expression to identify any word repeated five times or more consecutively in a given string. If such a word is found, the function returns that word; otherwise, it returns an empty string.

    # Regular expression pattern:
    # \b(\w+)\b - captures a whole word and stores it in group 1
    # (?:\s+\1\b){4,} - matches the same word preceded by whitespace, four or more times
    pattern = r'\b(\w+)\b(?:\s+\1\b){4,}'
    
    # Search for the pattern in the input string
    match = re.search(pattern, s)
    
    # If a match is found, return the captured word; otherwise, return an empty string
    return match.group(1) if match else ''

# Example usage:
# print(match("This is a test test test test test string"))  # Output: "test"
# print(match("No repetitions here"))                       # Output: ""
### How It Works: 1. **Pattern Explanation**: - `\b(\w+)\b`: This part captures a whole word and stores it in the first capturing group `(\w+)`. The `\b` ensures word boundaries, so partial matches are avoided. - `(?:\s+\1\b){4,}`: This non-capturing group looks for the same word captured in group 1 (`\1`) preceded by one or more whitespace characters (`\s+`). The `{4,}` quantifier ensures that this pattern repeats at least four more times, making it a total of five consecutive repetitions. 2. **Function Workflow**: - The `re.search()` function scans through the input string `s` looking for the first location where the regex pattern produces a match. - If a match is found, `match.group(1)` retrieves the repeated word. - If no match is found, the function returns an empty string. ### Example Cases: - **Case 1**: 
1
2
    print(match("hello hello hello hello hello"))  # Output: "hello"
The word "hello" is repeated five times consecutively. - **Case 2**: 
1
2
    print(match("This is a test test test test test string"))  # Output: "test"
The word "test" is repeated five times consecutively. - **Case 3**: 
1
2
    print(match("No repetitions here"))  # Output: ""
There are no words repeated five times consecutively. ### Notes: - The function is case-sensitive. If you want to make it case-insensitive (e.g., treating "Test" and "test" as the same word), you can modify the `re.search` call by adding the `re.IGNORECASE` flag: 
1
2
    match = re.search(pattern, s, re.IGNORECASE)
- The regex assumes that words are separated by whitespace characters like spaces, tabs, or newlines. Adjust the `\s+` part of the pattern if your definition of word separation differs.

Query

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.

Output

Certainly! Below is a Python function named `match` that utilizes regular expressions (regex) to identify and return any word repeated **five times or more consecutively** in a given string. If no such repetition is found, it returns an empty string. ### Function Explanation 1. **Import the `re` Module**: This module provides support for regular expressions in Python. 2. **Define the Regex Pattern**: - `\b`: Word boundary to ensure we're matching whole words. - `(\w+)`: Capturing group that matches one or more word characters (i.e., the word itself). - `(?:\s+\1){4,}`: A non-capturing group that looks for the same word (`\1` refers back to the first capturing group) preceded by one or more whitespace characters. `{4,}` specifies that this pattern should repeat **at least four more times**, making it five occurrences in total. 3. **Use `re.search`**: This function scans through the string, looking for the first location where the regex pattern produces a match. 4. **Return the Matched Word or an Empty String**: If a match is found, return the captured word; otherwise, return `""`. ### Code Implementation

# Example Usage:

Matched Word: 'test'

Input: No repetition here.
Matched Word: ''

Input: word word word word word word
Matched Word: 'word'

Input: Repeat repeat RePeat repeat repeat
Matched Word: 'Repeat'
### Notes - **Case Insensitivity**: The `re.IGNORECASE` flag allows the regex to match words irrespective of their case (e.g., "Repeat" and "repeat" are considered the same). - **Word Boundary (`\b`)**: Ensures that the pattern matches whole words and doesn't get confused by substrings within longer words. - **Adjusting the Pattern**: If you want to match words that are not necessarily consecutive but appear five times anywhere in the text, you'll need a different approach, possibly iterating through word counts instead of using a single regex pattern. Feel free to integrate and modify this function based on your specific requirements!
