Strings & text
Format, split, join, parse, and clean text — everyday Python string patterns.
How to parse key=value pairs in Python
Parse a single line of key=value pairs separated by a delimiter into a Python dictionary.
def parse_key_value_pairs(line: str, delimiter: str = "&") -> dict:
"""Parse a single line of key=value pairs into a dictionary."""
pairs = {}
for token in line.split(delimiter):
if not token.strip():
continue
key, _, value = token.partition("=")
pairs[key.strip()] = val…How to remove punctuation from a string in Python
Remove all punctuation characters from a string using the str.translate method and string.punctuation from the standard library.
import string
def remove_punctuation(text: str) -> str:
return text.translate(str.maketrans("", "", string.punctuation))
if __name__ == "__main__":
sample = "Hello, world! It's a test... (with punctuation) - done?"
cleaned = remove_punctuation(sample)
print(f"Original: {sample}")
print(f"Cleaned:…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)Normalize unicode accents to ASCII in Python
This code converts accented Unicode characters to ASCII equivalents using the standard library's unicodedata module.
import unicodedata
def normalize_accents(text: str) -> str:
"""Convert accented unicode characters to ASCII equivalents."""
decomposed = unicodedata.normalize('NFD', text)
ascii_text = ''.join(
char for char in decomposed
if unicodedata.category(char) != 'Mn'
)
return unicodedata.n…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()
def remove_punctuation(text):
…Python: Replace Spaces with Hyphens for Slug
Transform a string by stripping surrounding whitespace and replacing each space with a hyphen to create a simple slug.
def slugify(text):
return text.strip().replace(" ", "-")
if __name__ == "__main__":
title = "Hello World Python Example"
result = slugify(title)
print(result)Remove Substring Occurrences Case-Insensitively in Python
This code removes every case-insensitive occurrence of a given substring from a text string using a simple looping approach.
def remove_occurrences_ci(text: str, substring: str) -> str:
"""Remove all case-insensitive occurrences of substring from text."""
if not substring:
return text
result = []
i = 0
lower_text = text.lower()
lower_sub = substring.lower()
sub_len = len(substring)
while i <…String helpers in Python: stats, reverse, and remove vowels
Three beginner-friendly Python functions compute text statistics, reverse word order, and strip vowels from a string.
def text_stats(text: str) -> dict:
"""Return basic statistics for a given text string."""
words = text.split()
return {
"characters": len(text),
"words": len(words),
"sentences": text.count(".") + text.count("!") + text.count("?"),
"uppercase": sum(1 for c in text if c.isupp…Text Processor Functions for Beginners in Python
Demonstrates simple text-processing utilities: word counting, word reversal, whitespace normalization, and lowercase conversion using basic string methods.
def count_words(text):
"""Return the number of words in a string."""
return len(text.split())
def reverse_words(text):
"""Return the text with words in reverse order."""
return ' '.join(text.split()[::-1])
