3. Simple Integration into Existing Applications¶
The rootpy.ROOT
module is intended to be a drop-in replacement for
ordinary PyROOT imports by mimicking PyROOT’s interface. Both ROOT and rootpy
classes can be accessed in a harmonized way through this module. This means you
can take advantage of rootpy classes automatically by replacing import ROOT
with import rootpy.ROOT as ROOT
or from rootpy import ROOT
in your code,
while maintaining backward compatibility with existing use of ROOT’s classes.
Under rootpy.ROOT
, classes are automatically “asrootpy’d” after the
ROOT constructor has been called:
>>> import rootpy.ROOT as ROOT
>>> ROOT.TH1F('name', 'title', 10, 0, 1)
Hist('name')
Access rootpy classes under rootpy.ROOT
without needing to remember
where to import them from in rootpy:
>>> import rootpy.ROOT as ROOT
>>> ROOT.Hist(10, 0, 1, name='name', type='F')
Hist('name')
