pylhe.LHEEventInfo

class pylhe.LHEEventInfo(nparticles: int, pid: int, weight: float, scale: float, aqed: float, aqcd: float)

Bases: DictCompatibility

Store the event information in the LHE format.

__init__(nparticles: int, pid: int, weight: float, scale: float, aqed: float, aqcd: float) → None

Methods

__init__(nparticles, pid, weight, scale, ...)
clear()
fromstring(string)	Create an LHEEventInfo instance from a string in LHE format.
get(k[,d])
items()
keys()
pop(k[,d])	If key is not found, d is returned if given, otherwise KeyError is raised.
popitem()	as a 2-tuple; but raise KeyError if D is empty.
setdefault(k[,d])
tolhe()	Return the event info as a string in LHE format.
update([E, ]**F)	If E present and has a .keys() method, does: for k in E.keys(): D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v
values()

Attributes

fieldnames	Return the fieldnames.
nparticles	Number of particles in the event
pid	Process ID for the event
weight	Event weight
scale	Energy scale of the event
aqed	QED coupling constant alpha_QED
aqcd	QCD coupling constant alpha_QCD

aqcd: float

QCD coupling constant alpha_QCD

aqed: float

QED coupling constant alpha_QED

clear() → None.  Remove all items from D.

property fieldnames: list[str]

Return the fieldnames.

For backward compatibility with versions < 1.0.0.

Deprecated since version 1.0.0: Listing fieldnames via object.fieldnames is deprecated and will be removed in a future version.

classmethod fromstring(string: str) → LHEEventInfo

Create an LHEEventInfo instance from a string in LHE format.

get(k[, d]) → D[k] if k in D, else d.  d defaults to None.

items() → a set-like object providing a view on D's items

keys() → a set-like object providing a view on D's keys

nparticles: int

Number of particles in the event

pid: int

Process ID for the event

pop(k[, d]) → v, remove specified key and return the corresponding value.

If key is not found, d is returned if given, otherwise KeyError is raised.

popitem() → (k, v), remove and return some (key, value) pair

as a 2-tuple; but raise KeyError if D is empty.

scale: float

Energy scale of the event

setdefault(k[, d]) → D.get(k,d), also set D[k]=d if k not in D

tolhe() → str

Return the event info as a string in LHE format.

Returns:

str: The event info as a string in LHE format.

update([E, ]**F) → None.  Update D from mapping/iterable E and F.

If E present and has a .keys() method, does: for k in E.keys(): D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v

values() → an object providing a view on D's values

weight: float

Event weight
