Really nice ideas in @_inesmontani's #PyConIndia keynote: Let Them Code!

Some highlights:

* Multiprocessing shared memory
* The walrus operator :=
* The = format specifier for f-strings
* Much faster variable access for: globals, builtins, named tuples, class variables, and C function calls
* Beefed-up math and statistics modules

#Python tip: None and NotImplemented are singletons.

PEP 8 advises that comparisons for singletons should always be done with "is" or "is not", never the equality operators.

Are you applying multiple aggregations after a groupby? Try "named aggregation":

✅ Allows you to name the output columns
❌ Avoids a column MultiIndex

New in pandas 0.25! See example 👇
