下面程序的输出结果是______s = 'abc' try: for i in range(3): s[i] = 'a' print(s) except: print('Error')[/i]
举一反三
- 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)
- 阅读程序，输出结果： s=0 for i in range(1,101): s = s + i print('1+2+3+…+100 = ', s)
- s = {1,2,3}[br][/br] for i in s: print(i,end='') print() 以上程序输出结果为（ )
- 下列程序输出结果是（ ）。 i=1 s=0 while i<=3: s=s+i i=i+1 print(s) A: 1 B: 3 C: 6 D: 9
- 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
