在Python中,set是一種無序的數(shù)據(jù)類型,它存儲(chǔ)唯一的元素。當(dāng)你將一個(gè)列表轉(zhuǎn)換為集合時(shí),集合中的元素是無序的,這意味著你不能依賴于元素在集合中的特定順序。因此,當(dāng)你打印出一個(gè)集合時(shí),元素的順序可能會(huì)變化,這取決于Python的具體實(shí)現(xiàn)和你使用的Python版本。在你的代碼中,打印出的集合看起來似乎是有序的,但實(shí)際上這只是一種巧合。如果你再次運(yùn)行相同的代碼,或者在不同的Python環(huán)境中運(yùn)行,輸出的順序可能會(huì)有所不同。這是因?yàn)榧媳旧聿⒉槐WC元素的順序
