有如下 python 程序段: from random import* s='' for i in range(1,4): k=int(random( ?。?3+1) c=chr(96+k) if i%2==k%2: s=s+c else: s=c+s print(s) 若該段程序執(zhí)行以后,s 的值不可能的是( ?。?/h1>
3.有程序代碼如下,輸入某數(shù)據(jù)后,輸出結(jié)果為“B”。那么輸入的數(shù)據(jù)可能是( ) Dim score As Integer score=Val(InputBox(“score:“)) If score>89 Then Print“A“ Else If score>59 Then Print“B“ Else Print“C“ End If End If
