ここを書かなくてもwhileがskipされてTrueが返りますが、あってもいいとも思います。

return alphanumerics == list(reversed(alphanumerics)) で良い気がします。
あと、list(reversed(alphanumerics)) は alphanumerics[::-1] と書くこともできますね。

そうですね。
return alphanumerics == list(reversed(alphanumerics))
の方が簡潔でよさそうです
list(reversed(alphanumerics)) は alphanumerics[::-1] と書くこともできますね。
ですね。自分はreverseが文字にはいっていて意図が伝わりやすいと思っているので, 今のやり方を使うことが多いです
