BioSimSpace.Types.Charge¶

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

A charge type.

__init__(*args)[source]¶

Constructor.

*args can be a value and unit, or a string representation of the charge, e.g. “0.2 e”.

Parameters:

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

Examples

Create an object representing a charge of 27.8 electron charge print the charge in Coulomb.

>>> import BioSimSpace as BSS
>>> charge = BSS.Types.Charge(27.8, "e")
>>> print(charge.coulomb())

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

>>> import BioSimSpace as BSS
>>> charge = BSS.Types.Charge("3.1 atm")
>>> print(charge.coulomb())

The string matching is extremeley flexible, so all of the following would be valid arguments: “27.8 e”, “27.8 electron charge”, “2.78e1 e”.
