Manipulating lists, basic mathematical functions and LaTeX-like writing

Rathureqpy - A Python Utility Library

Rathureqpy is a Python library that provides a set of useful functions for a variety of tasks including list manipulation, mathematical operations, logical operations, statistical measures, and more.

Installation

You can install Rathureqpy by running:

bash pip install rathureqpy

Features

List Operations

• zero(number): Returns a list of zeros with the specified length.

• prod(L, a): Returns a new list with each element of L multiplied by a.

• addl(*args): Adds corresponding elements from multiple lists of equal length.

• linespace(start, end, step): Generates a list of evenly spaced values between start and end with a given step.

• array(start, end, n): Generates an array of n evenly spaced values between start and end.

• uni(*lists): Flattens multiple lists into a single list.

• uniwd(*lists): Flattens multiple lists into a single list and removes duplicates.

• inter(*lists): Returns the intersection of multiple lists.

• uniq(L): Returns a list with unique elements from L.

• moy(L): Returns the mean of a list L.

• sum_int(start, end): Returns the sum of integers between start and end.

• randl(min, max, n): Generates a list of n random integers between min and max.

• shuffle_list(L): Returns a shuffled version of L.

• filtrer(L, condition): Filters L based on a condition.

• chunk(L, n): Splits L into chunks of size n.

• partition(L, condition): Partitions L into two lists based on a condition.

Logical Operations

• binr(n): Converts an integer n to its binary representation as a string.

• change_base(value, inp_base, out_base): Converts value from inp_base to out_base.

• divisor_list(n): Returns a list of divisors of n.

• dicho(start, end, f, eps): Performs binary search to find the root of the function f in the interval [start, end] with an error tolerance eps.

• size(point_A, point_B): Calculates the distance between two points A and B in a 2D space.

Constants

• pi: Returns the constant \u03C0.

• e: Returns the constant e.

• tau: Returns the constant \u03C4 (2\u03C0).

Mathematical Operations

• abs(x): Returns the absolute value of x.

• cos(x): Returns the cosine of x.

• sin(x): Returns the sine of x.

• log(x, base=e()): Returns the logarithm of x to the specified base.

• exp(x): Returns the exponential of x.

• sqrt(x): Returns the square root of x.

• facto(n): Returns the factorial of n.

• floor(x): Returns the largest integer less than or equal to x.

• ceil(x): Returns the smallest integer greater than or equal to x.

• rint(x): Returns the integer closest to x (rounding halfway cases away from zero).

• gcd(a, b): Returns the greatest common divisor of a and b.

• lcm(a, b): Returns the least common multiple of a and b.

• is_prime(n): Checks if n is a prime number.

• integ(f, a, b, N) : Calculates the integral of f from a to b using the trapezoidal rule, with a sign adjustment if a > b

Statistical Measures

• variance(L): Returns the variance of the list L.

• ecart_type(L): Returns the standard deviation of the list L.

• mediane(L): Returns the median of the list L.

• decomp(n): Returns the prime factorization of n as a list of tuples.

• list_prime(n): Returns a list of all prime numbers up to n.

• pascal_row(n): Returns the n-th row of Pascal's Triangle.

Mathematical Language LaTeX-like

• lat(expr): Converts a simple LaTeX-like string expr into Unicode math characters. Supports: exponents (^), indices (_), square roots (sqrt(...)), sums (sum{...}^...), products (prod{...}^...), integrals (int), and fractions (frac{...}{...}).

• symbol(sym): Returns the Unicode math symbol corresponding to the LaTeX command sym. If the command is unknown, returns [unknown: sym].

• dot(text): Returns the input string text with a dot placed above each character.

• vec(text): Returns the input string text with a bar placed above each character.

• greek(expr): Converts the Greek letter name expr into its corresponding Unicode symbol. Returns an empty string if the name is not recognized.

• italic(text): Converts the input string text to italic Unicode mathematical characters. Only English letters (a-z, A-Z) are transformed.

• bold(text): Converts the input string text to bold Unicode mathematical characters. Only English letters (a-z, A-Z) are transformed.

• mathbb(text): Converts the input string text to double-struck (blackboard bold) Unicode characters. Only English letters (a-z, A-Z) are transformed.

• cursive(text): Converts the input string text to cursive (script) Unicode characters. Only English letters (a-z, A-Z) are transformed.
