How to build a text helper in Python for beginners
This code provides easy-to-use functions for cleaning text, removing punctuation, counting word frequencies, and summarizing strings — perfect for beginners.
def clean_text(text: str) -> str:
"""Clean and normalize a text string."""
text = text.strip()
text = text.replace(" ", " ")
text = text.capitalize()
text = text.replace(".", ".")
return text

"""Remove common punctuation marks from a string."""
…How to wrap long text to a specified width in Python
Uses Python's textwrap.fill to wrap a long string to a specified width at word boundaries, preserving readability in console output or logs.
import textwrap
text = """This is a long piece of text that definitely exceeds the width limit
if we try to print it on a single line without any wrapping applied."""
wrapped = textwrap.fill(text, width=40)
print(wrapped)Python String Helper Functions for Beginners
A set of beginner-friendly Python functions that count words, reverse text, convert to title case, strip punctuation, and compute character frequency from a string.
def count_words(text):
"""Count the number of words in a string."""
return len(text.split())
def reverse_text(text):
"""Reverse the entire string."""
return text[::-1]
def title_case(text):
"""Capitalize the first letter of each word."""
return text.title()

…Reverse Words in a Sentence While Keeping Punctuation in Python
Reverses the order of words in a sentence while leaving punctuation and spaces in their original positions using Python's re module.
def reverse_words_preserving_punctuation(sentence: str) -> str:
import re
# Split into words and punctuation tokens
tokens = re.findall(r'\w+|[^\w\s]|\s+', sentence)
words = [t for t in tokens if re.fullmatch(r'\w+', t)]
words.reverse()
result_parts = []
word_index = 0
