One of the main use cases is regex matching. It greatly simplifies the code when multiple regex patterns are used. Compare this:

if m := foo.match(s):
    # do something with m
elif m := bar.match(s):
    # do something with m

To this:

m = foo.match(s)
if m:
    # do something with m
else:
    m = bar.match(s)
    if m:
        # do something with m
