dog.instance_count?=?dog.instance_count+1 實(shí)際上不是在操作類屬性 而是在dog實(shí)例上新增了一個(gè) instance_count屬性，然后你再次訪問(wèn)的時(shí)候因?yàn)閮?yōu)先級(jí) 你訪問(wèn)不到類上的屬性了? 所以操作類屬性最好使用Animal.instance_count

z=y()? 調(diào)用的 最里面的h()函數(shù)，該函數(shù)沒(méi)有返回值，所以z是Nonedef?h():? ? ? ? ? ?print('call h()...')

上面寫的seek的函數(shù)用法是錯(cuò)的，。他那參數(shù)代表的是偏移量，1就是在一個(gè)字符后，2就是兩個(gè)字符后。。。。。。

?r1?=?Rational(1,?2)?這里是調(diào)用了Rational類的__init__方法創(chuàng)建了一個(gè)實(shí)例，然后將這個(gè)實(shí)例賦予給了r1；<...code...>這是調(diào)用了r1這個(gè)實(shí)例的__add__方法，self是指實(shí)例本身也就是r1，而r這個(gè)參數(shù)就是指代r2，下文兩個(gè)語(yǔ)句是等價(jià)的<...code...>從這地方引申出來(lái)，假設(shè)還有一個(gè)r3，那程序是怎么跑的呢<...code...>程序會(huì)先算r1+r2，然后再用這個(gè)算出的結(jié)果x去+r3
