eapy

A Python utility library that extends the standard library with math, algebra, data structures, and everyday tools.

Features

Math & Algebra

• numericalIntegral(f, a, b) — Simpson's rule integration

Utility & Decorators

• Timer — simple stopwatch timer
• clamp, lerp, mapRange — numeric helpers
• flatten, chunk, deepGet, uniqueId — data helpers
• @retry, @memoize, @deprecated, @singleton — decorators

• getPath — interactive file/directory picker
• repeatUntilSecond, repeatUntilSecondOrBool, repeatUntilValueChange — loop helpers

Broadcast / Messaging

• whenGetMessage, broadcast, broadcastWithData — simple event system

Installation

pip install -i https://test.pypi.org/simple/ eapyTool

Quick Start

from eapy.core import Var, Polynomial, Vector3D, mean

# Symbolic algebra
x = Var('x')
expr = (x + 2) * (x + 3)
print(expr.evaluate(x=5))  # 56.0

# Polynomial
p = Polynomial([1, -3, 2])  # 1 - 3x + 2x^2
print(p.derivative())        # -3 + 4*x
print(p(10))                 # 171.0

# Vector
v = Vector3D(1, 2, 3)
print(v.abs())               # 3.7416...

# Statistics
print(mean([4, 8, 15, 16, 23, 42]))  # 18.0
