python - Verify if a topic exists based on topic name -


i'm trying verify if topic exists based on topic name.

do know if possible?

for example want verify if topic name "test" exist.

below i'm trying doesn't work because topicslist contains topicarns , not topicnames...

topics = sns.get_all_topics()    topicslist = topics['listtopicsresponse']['listtopicsresult'['topics']  if "test" in topicslist:     print("true")

this kind of hack should work:

topics = sns.get_all_topics()    topic_list = topics['listtopicsresponse']['listtopicsresult']['topics'] topic_names = [t['topicarn'].split(':')[5] t in topic_list]  if 'test' in topic_names:    print(true)

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
