BioSimSpace.Types.Length¶

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

A length type.

__init__(*args)[source]¶

Constructor.

*args can be a value and unit, or a string representation of the length, e.g. “12 Angstrom”.

Parameters:

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

Examples

Create an object representing a length of 148.6 Angstrom then print the length in nanometers.

>>> import BioSimSpace as BSS
>>> length = BSS.Types.Length(148.6, "A")
>>> print(length.nanometers())

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

>>> import BioSimSpace as BSS
>>> length = BSS.Types.Length("148.6 A")
>>> print(length.nanometers())

The string matching is extremeley flexible, so all of the following would be valid arguments: “148.6 A”, “148.6 angstrom”, “1.48e2 Angstrom”.
