Python interface to read Les Houches Event (LHE) files.

Functions

read_lhe(filepath)	Read and yield the events in the LHE file.
read_lhe_file(filepath[, with_attributes])	Read an LHE file and return an LHEFile object.
read_lhe_init(filepath)	Read and return the init blocks.
read_lhe_with_attributes(filepath)	Iterate through file, similar to read_lhe but also set weights and attributes.
read_num_events(filepath)	Moderately efficient way to get the number of events stored in a file.
write_lhe_file(lheinit, lheevents, filepath)	Write the LHE file.
write_lhe_file_path(lhefile, filepath[, gz, ...])	Write the LHE file.
write_lhe_file_string(lhefile[, rwgt, weights])	Return the LHE file as a string.
write_lhe_string(lheinit, lheevents[, rwgt, ...])	Return the LHE file as a string.

Classes

LHEEvent(eventinfo, particles[, weights, ...])	Store a single event in the LHE format.
LHEEventInfo(nparticles, pid, weight, scale, ...)	Store the event information in the LHE format.
LHEFile(init[, events])	Represents an LHE file as a dataclass.
LHEInit(initInfo, procInfo, weightgroup, ...)	Store the <init> block as a dataclass.
LHEInitInfo(beamA, beamB, energyA, energyB, ...)	Store the first line of the <init> block as a dataclass.
LHEParticle(id, status, mother1, mother2, ...)	Represents a single particle in the LHE format.
LHEProcInfo(xSection, error, unitWeight, procId)	Store the process info block as a dataclass.
LHEWeightGroup(attrib, weights)	Information about a weight group.
LHEWeightInfo(attrib, name, index)	Information about a single weight in a weight group.
