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

()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
Return the fieldnames.
Number of particles in the event
Process ID for the event
Event weight
Energy scale of the event
QED coupling constant alpha_QED
QCD coupling constant alpha_QCD
- aqcd: float

- 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 [source]
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 [source]
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
