I tried to read this. I love Python, and am thrilled to see the language evolve.

This page has a massive sidebar, another massive sidebar that scrolls with the content, and another sidebar. The content for my screen had about 1" width to read.

The various sidebars inexplicable start and stop scrolling as I scrolled down, meaning I got through 1/4 and closed the tab.

Atrocious and anti-user.

The examples were good, so it's worse than just "yet another python page filled with ads". But I'll summarize them:

* First example, merge with update:

    # d1 and d2 being dicts
    d3 = d1.copy()
    d3.update(**d2)

* Second example, using dict():

    d3 = dict(d1, **d2)

* Third example (3.9 onwards):

    d3 = d1 | d2
    # or
    d3 = d1.copy()
    d3 |= d2

The examples also show how each operation works (tl;dr: last value assigned to a key "wins").
