语句()会输出1、2、3三个数字。
A: for a in range(3):
print(a)
B: i=1
while
i<3:
print(i)
i+=1
C: aList=[1,2,3]
for
i in range(3):
print(aList[i])
D: alist=[2,1,1,6,2,3,5,3,1,7]
for
x in alist[-3::-3]:
print(x)
A: for a in range(3):
print(a)
B: i=1
while
i<3:
print(i)
i+=1
C: aList=[1,2,3]
for
i in range(3):
print(aList[i])
D: alist=[2,1,1,6,2,3,5,3,1,7]
for
x in alist[-3::-3]:
print(x)
举一反三
- 下面代码中输出结果为1,2,3三个数字的有（）。 A: i=1 while i<3: print(i) <br> i+=1 B: i=3 while i>0: i=i-1 <br> print(3-i) C: for i in range(3): <br> print(i) D: alist=[0,1,2] for i in alist: <br> print(i+2)
- 下面的代码，哪些是输出1,2,3三个数字 ( )。 A: for i in range(3): print(i) print(i+1) B: aList = [0,1,2] for i in aList: print(i+1) C: i = 1 while i < 3: print(i) i+=1 D: for i in range(3): print(i+1)
- 下面代码中,能够输出数字1,2,3(不考虑输出格式)的是( ) A: for i in range(3):<br/>print(i) B: i=1<br/>while i<3: print(i) i=i+1 C: for i in range(3):<br/>print(i+1)
- 以下程序的输出结果是( )。[br][/br]for i in range(0,3):[br][/br]print(i,end=’ ’) A: 0 1 2 B: 1 2 C: 1 2 3 D: 0 1 2 3
- 下面代码中输出结果为1,2,3三个数字的有（）。 A: for i in range(3): print(i) B: alist=[0,1,2] for i in alist: print(i+1) C: i=1 while i<3: print(i) i+=1 D: for i in range(3,0,-1): print(i+1) E: i=3 while i>0: i=i-1 print(3-i)
