class snapshot(timepoints=None, *args, die=True, **kwargs)[source]#

Bases: Analyzer

Analyzer that takes a “snapshot” of the sim.people array at specified points in time, and saves them to itself. To retrieve them, you can either access the dictionary directly, or use the get() method.

  • timepoints (list) – list of ints/strings/date objects, the days on which to take the snapshot

  • die (bool) – whether or not to raise an exception if a date is not found (default true)

  • kwargs (dict) – passed to Analyzer


sim = hpv.Sim(analyzers=hpv.snapshot('2015.4', '2020'))
snapshot = sim['analyzers'][0]
people = snapshot.snapshots[0]            # Option 1
people = snapshot.snapshots['2020']       # Option 2
people = snapshot.get('2020')             # Option 3
people = snapshot.get(34)                 # Option 4
people = snapshot.get()                   # Option 5



Retrieve a snapshot from the given key (int, str, or date)
