The Python Shell Gramplet brings up an interactive Python Shell for interpreting python expressions.
Options
You can type most any (single line) Python expression.
In addition, the environment has been populated with some useful variables, including
- self - (this Python gramplet)
- Date - a date object constructor, that can be used for date arithmetic.
- db - Interact with the Database
- dbstate - Information about the Database
- gc - the Python "garbage collector" preloaded with the same flags as the Debug Tool.
- uistate - Interact with the GUI
When the Python Shell Gramplet is detached you can select the Help button to see this page.
Examples
The Date entry is a date object constructor, and can be used for date arithmetic. For example, you might be interested in questions like:
What was the date 56 years before a given date:
> Date(2007, 12, 31) - 56 1951-12-31
How old was someone on Sept 3, 1955 who was born on June 7, 1922:
> Date(1955, 9, 3) - Date(1922, 5, 7) 33 years, 3 months
When did they turn 21 years old?
> Date(1922, 5, 7) + 21 1943-05-07
You can also add years, months, and days:
> Date(1980) + (0, 0, 25) 1980-01-26
You can convert one date into another calendar, which returns a new date object:
> Date(1703, 6, 1).to_calendar("hebrew") 5463-10-17 (Hebrew)
Developers
Another use for this Gramplet is for debugging. This gramplet makes a nice interface to the running Gramps system. You can inspect, and alter the system by entering Python commands. As a simple example, you can:
> self.clear_text() # clear the text in this window > self.set_wrap(False) # turn word wrap off > self.set_wrap(True) # turn word wrap on
The Python Gramplet also has the Python "garbage collector" preloaded with the same flags as the Debug Tool. To use:
> gc.collect() 23 > gc.garbage[0] <cell at 0x9f9089c: function object at 0x9f89dbc> > gc.get_referents(self) [...] > gc.get_referrers(self) [...]

You can use the Python Shell to interact with people from your database and test Gramps functions:
Gramps 3.x | > person = db.get_person_from_gramps_id("I01284") > from Utils import probably_alive > probably_alive(person, db, Date(1776, 7, 4)) |
---|---|
Gramps 4.x | > person = db.get_person_from_gramps_id("I01284") > from gen.utils.alive import probably_alive > probably_alive(person, db, Date(1776, 7, 4)) |
You can also interact with the GUI:
This following returns the Gtk Frame of the first Gramplet in the first column.

Gramps 4.x |
This following returns a reference to a loaded Gramplet object on the Event view - useful when developing Gramplets. Note that the Events view must be navigated first, as main views are lazy loading in Gramps 4.
Gramps 4.x | > evtview = uistate.viewmanager.pages[uistate.viewmanager.page_lookup.get((5,0))] > # list all TabGramplet objects loaded for Events view > [child.get_title() for child in evtview.bottombar.get_children()] ['Gallery', 'Citations', 'Notes', 'Attributes', 'References', 'Event PlaceTitle Compare Gramplet'] > # get a reference to my custom Gramplet object > eptcGramplet = evtview.bottombar.get_children()[5].pui |
