hello 对应 {0}，short 对应 {1}，python 对应 {2}。hello 对应 {0}，short 对应 {1}， python 对应 {2}你 temp3 里没有 {0}，自然就不会打印 hello，建议改成：<...code...>

L = [[1, 2, 3], [5, 3, 2], [7, 3, 2]]
s1=L[0][0]*L[0][1]*L[0][2]
print(s1)
s1=L[0][0]*L[0][1]*L[0][2]
print(s1)

参考答案有问题吧，应该是
hello='Hello'
space=' '
world='World'
print(hello+space +world)
hello='Hello'
space=' '
world='World'
print(hello+space +world)

L = ['Alice', 66, 'Bob', True, 'False', 100]
for item in L:
i=L.index(item)
if(i%2)!=0:
print(item)
for item in L:
i=L.index(item)
if(i%2)!=0:
print(item)
