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)
5050
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)
- 下列程序中输出结果为5050的是 A: s=0for i in range(100,-1): s=s+iprint(s) B: s=0for i in range(100,1,-1): s=s+iprint(s) C: s=0for i in range(100): s=s+iprint(s) D: s=0for i in range(101): s=s+iprint(s)
- 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
- 执行下列程序段后，程序的运行结果为()。 s = 1 For i = 1 To 3 For j = 0 To i - 1 s = s + s * j Next j Print s; Next i
- 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]
