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").
