自 Python 2.5 以後，內建 all() 與 any() 可用來判別选代子是否存有任何值為真或假。
以碼演義：
1 >>> GoodSoulsComeToRest = ['Strangefolk', ('Monkey', 'Happyfolk') ]
2 >>> all( GoodSoulsComeToRest )
3 True
4 >>> GoodSoulsComeToRest = [ 0, ('Monkey', 'as 0 appear in here...') ]
5 >>> all( GoodSoulsComeToRest )
6 False
7 >>> any( GoodSoulsComeToRest ) # Monkey strings still there
8 True
9 >>> black = 0,0,0,0,0,0
10 >>> ManInBlack = [man for man in black] # Just a 0-list clone
11 >>> any( ManInBlack )
12 False
13 >>> all( ManInBlack ) # Since no any, of course not all
14 False
