Aug 07, 2025 pm 07:14 PM使用defaultdict而不是普通dict的原因是它能自動(dòng)為不存在的鍵提供默認(rèn)值,避免KeyError并減少初始化檢查的代碼量;1.使用list作為默認(rèn)工廠可方便地對(duì)元素進(jìn)行分組;2.使用int可簡(jiǎn)化計(jì)數(shù)操作,新鍵默認(rèn)值為0;3.使用set可確保集合內(nèi)元素唯一,自動(dòng)去重;4.使用lambda等自定義函數(shù)可創(chuàng)建復(fù)雜結(jié)構(gòu)如嵌套字典;需注意默認(rèn)工廠僅在訪問(wèn)缺失鍵時(shí)觸發(fā),且必須是可調(diào)用對(duì)象,不能為None,合理使用可顯著提升代碼簡(jiǎn)潔性與健壯性。
