python3 problem
![画像:Problem 7 You implement your shuffling algorithm to make a playlist for a party containing n songs. You want to know what is the probability that the shuffled playlist contains at least one consecutive song (i.e. song 2 is followed by song 3). Write a function that returns True if the shuffled playlist contains such a song, and False otherwise. Example IO: consecutive song ([1,2,3]) #returns True if shuffle is [2,3,1] consecutive _song ([1 ,2 , 3]) #returns False if shuffle is [2 ,1 ,3]](https://content.bartleby.com/qna-images/question/2b8cc6d4-8603-42fd-9afc-5c52d6d32ece/2a95f64a-929f-46b4-896c-601f45e40c94/j44565h_thumbnail.png){kind=link}
