How to Parse and Clean Text in Python

This code defines three helper functions to parse text into lowercase words, count unique word frequencies, and clean text by removing punctuation and extra whitespace.

text parsing string cleaning word frequency
Python 
def extract_words(text: str) -> list[str]:
    """Return a list of lowercase words from the given text."""
    return [word.lower() for word in text.split() if word.isalpha()]


def count_unique_words(text: str) -> dict[str, int]:
    """Return a dictionary with unique words and their frequencies."""
    words = extra…

    """Split a string by a delimiter and return a list of parts."""
    return text.split(delimiter)

    lines = text.splitlines()
    items = []
    
    for line in lines:
        stripped = line.strip()
        if stripped.startswith("- ") or stripped.startswith("* "):
