Ele
Overview
Element is an extremely lightweight package that defines the elements of the periodic table and allows them to be accessed by symbol, name, atomic number, or mass. It has zero dependencies outside of the Python Standard Library.
Warning
Ele is still in early development (0.x releases). The API may change unexpectedly.
Usage
Ele only supports a few modes of use. You can retrieve an element from the symbol, the name, the atomic number, or the mass (in amu):
import ele
na = ele.element_from_symbol("Na")
na = ele.element_from_name("sodium")
na = ele.element_from_atomic_number(11)
na = ele.element_from_mass(22.990)
The mass is rounded to a single decimal before comparison. If you wish to
retrieve the element with the mass closest to the specified value you
may use the exact=False
keyword.
Each Element
has four attributes which can be accessed
(as demonstrated below for na
):
na.name
na.symbol
na.atomic_number
na.mass
The elements can also be accessed by symbol as follows:
import ele
na = ele.Elements.Na
Installation
Install via pip:
pip install ele
or conda:
conda install -c conda-forge ele
Installation from source is also an option:
git clone git@github.com/rsdefever/ele.git
cd ele
pip install .
