a=0print(a,end="")s=0while a[10: a=a+1 if a**2]50: continue s=s+aelse: print(s)
举一反三
- 【其它】写出并理解下列语句输出的结果 s = "hello" print(s[0]) print(s[4]) print(s[-1]) print(s[0:3]) print(s[0:4:2]) print(s[:]) print(s[:3]) print(s[::-1]) print(s[1:])
- 有如下程序段：s = 0For i = 1 To 10 s = s + iNext iPrint s与上述程序段输出结果相同的程序段为( )。 A: s = 0: i = 0 While i <= 10 i = i + 1 s = s + i Wend Print s B: s = 0: i = 1 While i < 10 i = i + 1 s = s + i Wend Print s C: s = 0: i = 1 Do s = s + i i = i + 1 Loop While i < 10 Print s D: s = 0: i = 1 Do s = s + i i = i + 1 Loop Until i > 10 Print s
- 下面程序计算并输出的是_______。 Private Sub Command1_Click() a=10 s=0 Do s=s+a*a*a a=a-1 Loop Until a<=0 Print s End Sub
- 16、下面程序的执行结果是______________。（1275） s = 0 for i in range(1,101): s += i if i == 50: print(s) break else: print(1)
- s = "Python", 能够显示输出Python 的选项是：（）。 A: print s[0:-1] B: print s[-1:0] C: print s[:5] D: print s[:]
