while语法的正确使用是（） A: whilei=（1<>10） B: while（i<=10） C: while（i<=10；i++） D: whilei=1to10

下面代码中输出结果为1,2,3三个数字的有（）。 A: i=1 whilei<3: print(i) i+=1 B: alist=[0,1,2] foriinalist: print(i+1) C: i=3 whilei>0: i=i-1 print(3-i) D: foriinrange(3): print(i)

_____ my computer whileI’m away. A: Not touch B: Don’t touch C: Not to touch

i=1whilei<3:#print(i)i=i+1print(i)输出3，对吗？

使用while循环实现计算n的阶乘。 输入样例 4 输出样例 4!=24 请将以下程序补充完整： n=【1】(input()) fact=1 i=1 whilei<=n: fact=【2】 i=【3】 print('{}!={}'.format(【4】))

下面的代码,哪些会输出1,2,3三个数字 A: foriinrange(3):print(i) B: aList=[0,1,2]foriinaList:print(i+1) C: i=1whilei<3:print(i)i+=1 D: foriinrange(5):print(i+1)

下面程序中，循环执行结束后，循环变量i的值为（）i=1whilei>=0:i-=1print(i)

下列选项中,会输出1、2、3三个数字的是()。 A: foriinrange(3):print(i) B: foriinrange(2):print(i+1) C: foriinrange(1,4):print(i) D: i=1whilei<3:print(i)i=i+1

for i in range(b.max_row): for j in range(b.max_column): print(b.cell(row=i,column=j).value)上面语句运行的结果是：__________。 A: 1 1 1 1 1 1 1 1 1 1 B: 1111111111 C: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 D: 出现异常
