# PyTomUtil
A collection of helpful utilties in Python.
Similar to the `tecoradors-elunico` package I have but that is just for useful decorators. This is any useful utility: function or class or other
## PyPI
Not yet published to PyPI but coming soon.
## Content
`frange` class works like `range` but allows floating point values. Requires `start`, `stop`, and `step` to always be specified
```python
class frange:
def __init__(self, start: float, stop: float, step: float) -> None:
...
def __iter__(self):
...
def __next__(self):
...
```
---
`lerp` is a function for linearly interpolating between two values according to a percentage between 0.0 and 1.0.
[Linear Interpolation in Wikipedia](https://en.wikipedia.org/wiki/Linear_interpolation)
```python
def lerp(a: float, b: float, t: float) -> float:
return (1 - t) * a + t * b
```
---
`SRGBColor` is a class for managing colors in SRGB color space. Works with linear interpolation between colors and `luminance` values. The class accepts r, g, b and optionally an alpha channel in the range 0.0 to 1.0.
```python
class SRGBColor:
def __init__(self, r: float, g: float, b: float, a: float = 1.0):
...
def lerp(self, other: "SRGBColor", percent: float) -> "SRGBColor":
...
@property
def luminance(self) -> float:
"""Given an sRGB color as 3 RGB values between 0 and 1, return their relative luminance"""
...
```
