python同时遍历两个或更多的序列，可以使用 zip() 组合：
questions=['name', 'question','favorite color']
answers=['lancelot', 'the holod', 'blue']
for q, a in zip(questions, answers):
print('what is your {0}? It is {1}.'.format(q, a))
oc 额，好像没有
NSArray *questions = @[@"name", @"question", @"favorite color"];
NSArray *answers = @[@"lancelot", @"the holod", @"red"];
[questions enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
NSLog(@"what is your %@? It is %@.", obj, answers[idx]);
}];
