morebuiltins 1.2.3

Expanding Python's built-in functionalities to enable richer and more versatile work scenarios.

morebuiltins

Project Overview:

This project enhances Python’s built-ins with extra functionality, prioritizing no third-party dependencies, performance, reusability, and MIT Licensing for flexible use.

• Minimal Dependencies: Designed to avoid third-party libraries for seamless integration, conflict prevention, and easy packaging via zipapp for pyz distribution.
• Performance-Driven: It prioritizes efficiency, ensuring enhanced built-ins maintain Python's performance standards.
• Self-Contained Modules: Functions and modules are standalone for simple reuse without dependencies.
• MIT Licensed: The open-source code is freely usable, modifiable, and distributable.
• Enhanced Built-ins: The project adds tools to Python's core functionality, simplifying and accelerating development.

1. morebuiltins.utils

1.1 ttime - Converts a timestamp to a human-readable timestring formatted as %Y-%m-%d %H:%M:%S.

1.2 ptime - Converts a timestring formatted as %Y-%m-%d %H:%M:%S back into a timestamp.

1.3 slice_into_pieces - Divides a sequence into “n” segments, returning a generator that yields “n” pieces.

1.4 slice_by_size - Slices a sequence into chunks of a specified “size”, returning a generator that produces tuples of chunks.

1.5 unique - Removes duplicate elements from a sequence while preserving the original order efficiently.

1.6 retry - A decorator that retries the decorated function up to “tries” times if the specified exceptions are raised.

1.7 guess_interval - Analyzes a sequence of numbers and returns the median, calculating intervals only if they are greater than or equal to the specified accuracy.

1.8 get_hash - Generates a hash string from the given input string.

1.12 read_time - Converts seconds into a more readable time duration string.

1.13 Validator - Validator for dataclasses.

1.14 stagger_sort - Ensures that identical groups are ordered and evenly distributed, mitigating data skew. The function does not alter the original list and returns a generator.

1.15 default_dict - Initializes a dictionary with default zero values based on a subclass of TypedDict.

1.16 always_return_value - Got a function always return the given value.

1.17 format_error - Extracts frame information from an exception, with an option to filter out “-packages” details by default. To shorten your exception message.

1.18 Trie - Transforms a standard dictionary into a trie structure that supports prefix matching.

1.19 GuessExt - Determines whether the input bytes of a file prefix indicate a compressed file format.

1.20 xor_encode_decode - Perform XOR encryption or decryption on the given data using a provided key.

1.21 is_running - Check if the given process ID is running.

1.22 set_pid_file - Sets a PID file to prevent multiple instances of a script or process from running concurrently.

1.23 get_paste - This module offers a simple utility for retrieving text from the system clipboard with tkinter.

1.24 set_clip - Copies the given text to the clipboard using a temporary file in a Windows environment.

1.25 switch_flush_print - Set builtins.print default flush=True.

1.26 unix_rlimit - Unix only. RLIMIT_RSS, RLIMIT_FSIZE to limit the max_memory and max_file_size

1.27 SimpleFilter - Simple dup-filter with pickle file.

1.28 FileDict - A dict that can be saved to a file.

1.29 PathLock - A Lock/asyncio.Lock of a path, and the child-path lock will block the parent-path.

1.30 i2b - Convert an int to bytes of a specified length, commonly used in TCP communication.

1.31 b2i - Convert a byte sequence to an integer.

1.32 get_hash_int - Generates a int hash(like docid) from the given input bytes.

1.33 iter_weights - Generates an element sequence based on weights.
