{"id":5442,"library":"python-string-utils","title":"Python String Utilities","description":"python-string-utils is a small utility library (version 1.0.0, last updated March 2020) that provides functions for string validation and manipulation. It aims to be simple, 'pythonic', fast (using compiled regex), and free from external dependencies, with 100% code coverage. Its release cadence has been infrequent, with the last major update in March 2020.","status":"maintenance","version":"1.0.0","language":"en","source_language":"en","source_url":"https://github.com/daveoncode/python-string-utils","tags":["string","utilities","validation","manipulation","regex"],"install":[{"cmd":"pip install python-string-utils","lang":"bash","label":"Install stable version"}],"dependencies":[],"imports":[{"note":"While importing from submodules like `string_utils.validation` works, the library makes all public API functions directly importable from the top-level `string_utils` package for convenience.","wrong":"from string_utils.validation import is_email","symbol":"is_email","correct":"from string_utils import is_email"},{"note":"Functions for string manipulation are available directly from the top-level package.","symbol":"prettify","correct":"from string_utils import prettify"}],"quickstart":{"code":"from string_utils import is_email, prettify, is_full_string\n\n# Example 1: Validate an email address\nemail = \"test@example.com\"\nprint(f\"'{email}' is a valid email: {is_email(email)}\")\n\n# Example 2: Prettify a string\nunprettified_string = \"  unprettified string ,, like this one,will be\\\"prettified\\\" . it' s awesome! \"\nprettified_string = prettify(unprettified_string)\nprint(f\"Original: '{unprettified_string}'\")\nprint(f\"Prettified: '{prettified_string}'\")\n\n# Example 3: Check for non-empty string\nempty_string = \"\"\nnon_empty_string = \"hello\"\nprint(f\"'{empty_string}' is a full string: {is_full_string(empty_string)}\")\nprint(f\"'{non_empty_string}' is a full string: {is_full_string(non_empty_string)}\")","lang":"python","description":"The quickstart demonstrates importing and using core validation and manipulation functions like `is_email`, `prettify`, and `is_full_string`.

Prioritize standard library solutions where they meet requirements for better maintainability and fewer external dependencies.","message":"Many string manipulation and validation tasks can now be handled efficiently and often more 'pythonically' using built-in Python features such as f-strings for formatting, the `re` module for complex regex patterns, and `pathlib` for robust path operations. Relying heavily on older utility libraries for these tasks might introduce unnecessary dependencies or overlook more idiomatic Python solutions.","severity":"gotcha","affected_versions":"All versions"},{"fix":"Be explicit about the string type you are expecting. If byte strings are a possibility, check `isinstance(obj, (str, bytes))` or convert byte strings to `str` before validation, e.g., `obj.decode('utf-8')`.","message":"The `is_string` function specifically checks if an object is of type `str` and returns `False` for byte strings (`bytes`).
