BioSimSpace.Types.Energy¶

class BioSimSpace.Types.Energy(*args)[source]¶

An energy type.

__init__(*args)[source]¶

Constructor.

*args can be a value and unit, or a string representation of the energy, e.g. “78.4 kcal/mol”.

Parameters:

value (float) – The value.
unit (str) – The unit.
string (str) – A string representation of the energy.

Examples

Create an object representing an energy of -1038 kilo calories per mol and print the energy in kilo joules per mol.

>>> import BioSimSpace as BSS
>>> energy = BSS.Types.Energy(-1038, "kcal/mol")
>>> print(energy.kj_per_mol())

The same as above, except passing a string representation of the energy to the constructor.

>>> import BioSimSpace as BSS
>>> energy = BSS.Types.Energy("-1038 kcal/mol")
>>> print(energy.kj_per_mol())

The string matching is extremeley flexible, so all of the following would be valid arguments: “-1038 kcal/mol”, “-1.038e3 kcal/mol”, “-1038 kilo cal per mol”.
