import FWCore.ParameterSet.Config as cms myParams = cms.PSet( name = cms.string("John"), age = cms.int32(30), isMarried = cms.bool(True) )
import FWCore.ParameterSet.Config as cms process = cms.Process("myProcess") process.load("myConfigFile_cff") # access parameters in the imported file myParams = process.myConfigFile.myParams
import FWCore.ParameterSet.Config as cms myParams = cms.PSet( name = cms.string("John"), age = cms.int32(30), isMarried = cms.bool(True) ) # modify a parameter myParams.isMarried = cms.bool(False) # add a new parameter myParams.height = cms.double(1.8)In this example, we modify an existing parameter set by changing the value of one key and adding a new key-value pair. This allows us to easily tweak configurations and explore different scenarios without having to rewrite everything from scratch. Overall, FWCore.ParameterSet Config is a powerful tool for managing configuration data in complex scientific applications, particularly in the field of High Energy Physics. With its modular and hierarchical structure, it allows researchers and developers to more easily manage their workflows and ensure the integrity of their data.
