這是一種代碼簡(jiǎn)寫的方式，稱之為推導(dǎo)式，是通過一行代碼完成循環(huán)判斷，并遍歷出一系列數(shù)據(jù)的編寫代碼方式。語(yǔ)法為：成員 for 循環(huán) ... if 判斷 ...而例子中的是為推導(dǎo)式中的一種類型，為列表推導(dǎo)式，結(jié)果是一個(gè)列表：?[item for item in Iterable]所以 result = [item for item in map(lambda x: x * x, [1, 2, 3, 4, 5, 6, 7, 8, 9])] 是這一段的簡(jiǎn)寫：result = []for i in? map(lamb...
