FYI:

Hamilton Python Meetup (New Zealand Python Users' Group)
Monday, September 12, 2022 at 7:00 PM to 9:00 PM NZST (0700~0900 UTC)

Lawrence D'Oliveiro will introduce the *"ast" module* (part of the
standard library) for abstract syntax trees, which can be used for
parsing Python files and retrieve information like doc strings, imports,
functions. etc.

Under traffic light setting Orange, the meeting will be a mix of
in-person (requirements: mask, social distancing) and virtual. Under
Red, it will be virtual only.
The in-person meeting part will take place in MS4.G.02:

The URL for the virtual meeting part will be made available to those who
RSVP.

NB I am not one of the group's organisers, but meetings are usually
recorded. More info from PeterR (via the Meetup page).
The time-zone 'works' for late-owls on the US West Coast, folk all
around the Pacific Rim, and covering the day all the way west around the
globe to Europeans and Brits enjoying their breakfast.
"traffic light setting Orange...red" are levels of COVID-response, and
irrelevant to those of us 'beaming-in' virtually.
