ToTemp

ToTemp is a temperature conversion package with Celsius, Delisle, Fahrenheit, Kelvin, Rankine, Réaumur, Newton and Rømer scales.

For more information read the docs.

This package aims to bring the simple and straight to the point, but precise, Object Oriented experience of working with temperature scale data types.

Usage

First of all, install the package:

pip install totemp

or, to have an example in poetry environments:

poetry add totemp

For more information, read the docs: [ToTemp Docs]('insert link here')

The instances:

from totemp import Celsius, Fahrenheit

if __name__ == '__main__':
    temps: list = [Celsius(12), Celsius(25), Celsius(50)]
    print(temps[0])  # '12 ºC'
    print(temps)  # [Celsius(12), Celsius(25), Celsius(50)]

    temps = list(map(Celsius.to_fahrenheit, temps))
    print(temps[0])  # '53.6 ºF'
    print(temps)  # [Fahrenheit(53.6), Fahrenheit(77.0), Fahrenheit(122.0)]

It's representations and properties:

Property symbol is read-only.

from totemp import Fahrenheit

if __name__ == '__main__':
    temp0 = Fahrenheit(53.6)
    print(temp0.__repr__())  # 'Fahrenheit(53.6)'
    print(temp0.__str__())  # '53.6 ºF'
    print(temp0.symbol)  # 'ºF'
    print(temp0.value)  # 53.6

Comparision operations ('==', '!=', '>', '>=', '<',...):

The comparision/arithmetic implementation attempts to convert the value of other (if it is a temperature instance) and then evaluate the expression.

import totemp as tp

if __name__ == '__main__':
    temp0, temp1 = tp.Celsius(0), tp.Fahrenheit(32)

    print(f'temp0: {repr(temp0)}')  # Celsius(0)
    print(f'temp1: {repr(temp1.to_celsius())}')  # Celsius(0.0)

    print(temp0 != temp1)  # False

    print(temp0 > temp1)  # False

    print(temp0 < temp1)  # False

    print(temp0 >= temp1)  # True

    print(temp0 <= temp1)  # True

    print(temp0 == temp1)  # True

Arithmetic operations ('+', '-', '*', '**', '/', '//', '%', ...):

from totemp import Newton, Rankine

if __name__ == '__main__':
    temp0 = Newton(33)
    temp1 = Rankine(671.67)

    temp2 = temp0 + temp1

    print('temp2:', temp2)  # temp2: 65.99999999999999 ºN
    print('temp2:', repr(temp2))  # temp2: Newton(65.99999999999999)
    print('temp2:', temp2.value, temp2.symbol)  # temp2: 65.99999999999999 ºN

    print((temp0 + temp1).rounded())  # 66 ºN
    print(repr((temp0 + temp1).rounded()))  # Newton(66)

    print(temp2 + 12.55)  # 78.54999999999998 ºN
    print((12 + temp2.rounded()))  # 78 ºN

ToTemp classes can work with many built-in Python functions:

from math import floor, ceil, trunc

from totemp import Reaumur

if __name__ == '__main__':
    temp = Reaumur(100.4)

    float(temp)  # 100.4
    int(temp)  # 100
    round(temp)  # Reaumur(100)
    abs(temp)  # Reaumur(100)
    floor(temp)  # Reaumur(100)
    ceil(temp)  # Reaumur(101)
    trunc(temp)  # Reaumur(100)
    divmod(temp, temp0 := Reaumur(25.1))  # (Reaumur(4.0), Reaumur(0.0))

Temperature Instance Conversions:

import totemp

if __name__ == '__main__':
    temp = totemp.Fahrenheit(32)

    print(temp.to_celsius())  # 0.0 ºC
    print(temp.to_fahrenheit())  # 32 ºF
    print(temp.to_delisle())  # 150.0 ºDe
    print(temp.to_kelvin())  # 273.15 K
    print(temp.to_newton())  # 0.0 ºN
    print(temp.to_rankine())  # 491.67 ºR
    print(temp.to_reaumur())  # 0.0 ºRé
    print(temp.to_romer())  # 7.5 ºRø
