Some Python functional tests still use plain `assert x == y`. The earlier commits convert the ambiguous assert patterns by hand, so this commit can rewrite the remaining safe cases mechanically. The verify script excludes `wallet_bumpfee.py`, `test_framework/netutil.py`, and `test_framework/authproxy.py`, which still contain assert forms that the plain line-based substitution would misidentify. -BEGIN VERIFY SCRIPT- perl -pi -e 's/^(\s*)assert (.+?) == ([^,#]+?)$/\1assert_equal(\2, \3)/' $(git ls-files -- 'test/functional' \ ':(exclude)test/functional/wallet_bumpfee.py' ':(exclude)test/functional/test_framework/netutil.py' ':(exclude)test/functional/test_framework/authproxy.py') -END VERIFY SCRIPT-
