Installation

You can install FunStrings directly from PyPI:

pip install funstrings

Or install from source:

pip install git+https://github.com/nilkanth02/funstrings.git

Quick Start

import funstrings

# Basic operations
text = "Hello, World!"
print(funstrings.reverse_string(text))  # !dlroW ,olleH
print(funstrings.count_vowels(text))    # 3

# Text analysis
sentence = "The quick brown fox jumps over the lazy dog"
print(funstrings.is_pangram(sentence))  # True
print(funstrings.longest_word(sentence))  # quick

# Transformations
snake = "hello_world_example"
print(funstrings.snake_to_camel(snake))  # helloWorldExample

# Pattern-based
text_with_emails = "Contact us at [email protected] or [email protected]"
print(funstrings.extract_emails(text_with_emails))  # ['[email protected]', '[email protected]']

# Data cleaning
html_text = "<p>Hello <b>World</b></p>"
print(funstrings.remove_html_tags(html_text))  # Hello World
print(funstrings.expand_contractions("I don't know"))  # I do not know

# Text analysis helpers
print(funstrings.sentence_count("Hello! How are you? I'm fine."))  # 3
print(funstrings.most_common_word("hello world hello python"))  # hello

# ML/NLP preprocessing
print(funstrings.generate_ngrams("hello", 2))  # ['he', 'el', 'll', 'lo']
print(funstrings.strip_accents("café"))  # cafe

# Validation
print(funstrings.is_valid_email("[email protected]"))  # True
print(funstrings.is_valid_url("https://example.com"))  # True
