class hapsira.bodies.Body¶

Bases: namedtuple('_Body', ['parent', 'k', 'name', 'symbol', 'R', 'R_polar', 'R_mean', 'rotational_period', 'J2', 'J3', 'mass', 'mean_a'])

Built-in immutable sequence.

If no argument is given, the constructor returns an empty tuple. If iterable is specified the tuple is initialized from iterable’s items.

If the argument is a tuple, the return value is the same object.

property angular_velocity¶

__slots__ = ()¶

__str__()¶: Return str(self).

__reduce__()¶: Helper for pickle.

__repr__()¶: Return repr(self).

classmethod from_parameters(parent, k, name, symbol, R, **kwargs)¶

classmethod from_relative(reference, parent, k, name, symbol=None, R=0, **kwargs)¶

__add__()¶: Return self+value.

__contains__()¶: Return key in self.

__delattr__()¶: Implement delattr(self, name).

__dir__()¶: Default dir() implementation.

__eq__()¶: Return self==value.

__format__()¶: Default object formatter.

__ge__()¶: Return self>=value.

__getattribute__()¶: Return getattr(self, name).

__getitem__()¶: Return self[key].

__getnewargs__()¶

__gt__()¶: Return self>value.

__hash__()¶: Return hash(self).

__iter__()¶: Implement iter(self).

__le__()¶: Return self<=value.

__len__()¶: Return len(self).

__lt__()¶: Return self<value.

__mul__()¶: Return self*value.

__ne__()¶: Return self!=value.

__reduce_ex__()¶: Helper for pickle.

__rmul__()¶: Return value*self.

__setattr__()¶: Implement setattr(self, name, value).

__sizeof__()¶: Size of object in memory, in bytes.

__subclasshook__()¶

Abstract classes can override this to customize issubclass().

This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached).

count()¶: Return number of occurrences of value.

index()¶

Return first index of value.

Raises ValueError if the value is not present.
